      Abstract: AbstractOBJECTIVESWe assessed the safety, effectiveness and haemodynamic performance of a new bovine stented aortic valve bioprosthesis (Avalus™).METHODSThe PERIGON Pivotal Trial is a prospective, non-randomized, multicentre study. Subjects had symptomatic moderate or severe aortic stenosis or chronic, severe aortic regurgitation. Death, valve-related adverse events (AEs), functional recovery and haemodynamic performance were assessed at discharge, 3–6 months and 1 year. The primary analysis compared ‘late’ (>30 days post-implant) linearized rates of valve-related thromboembolism, thrombosis, all and major haemorrhage, all and major paravalvular leak (PVL) and endocarditis after implantation with objective performance criteria (OPC) for AEs, in accordance with EN ISO 5840:2009. We hypothesized that the upper 95% confidence bounds of the true linearized AE rates would be ≥ 2 × OPC; rejection of the null hypothesis would demonstrate that these rates were below acceptable rates. The analysis was required to include at least 150 patients followed to 1 year and 400 valve-years. Kaplan–Meier survival analysis was also performed.RESULTSTotal number of valve-years was 459.5 (n = 686). Linearized rates were <2 × OPC for death and valve-related thromboembolism, valve thrombosis, all and major PVL, and endocarditis, but ≥2 × OPC for all and major haemorrhage. Survival at 1 year (n = 270) was 96.4%. Patients showed good functional recovery, and haemodynamic performance was within expected range.CONCLUSIONSThis analysis demonstrated a good safety profile and clinical effectiveness of the Avalus valve except for bleeding rates. The linearized rates of all and major haemorrhage may be related to long-term anticoagulation for non-valvular indications and the length of follow-up of this cohort.Trial registrationNCT02088554 (www.clinicaltrials.gov).

      Abstract: AbstractOBJECTIVESThe COMMENCE trial was conducted to evaluate the safety and effectiveness of a novel bioprosthetic tissue for surgical aortic valve replacement (AVR).METHODSPatients underwent clinically indicated surgical AVR with the Carpentier-Edwards PERIMOUNT™ Magna Ease™ aortic valve with RESILIA™ tissue (Model 11000A) in a prospective, multinational, multicentre (n = 27), single-arm, FDA Investigational Device Exemption trial. Events were adjudicated by an independent Clinical Events Committee; echocardiograms were analysed by an independent Core Laboratory.RESULTSBetween January 2013 and February 2016, 689 patients received the study valve. Mean age was 67.0 ± 11.6 years; 71.8% were male; 26.3% were New York Heart Association Class III/IV. Mean STS PROM was 2.0 ± 1.8 (0.3–17.5). Isolated AVR was performed in 59.1% of patients; others had additional concomitant procedures, usually CABG. Thirty-day outcomes for all patients included all-cause mortality 1.2%, thromboembolism 2.2%, bleeding 0.9%, major paravalvular leak 0.1% and permanent pacemaker implantation 4.7%. Median intensive care unit and hospital length of stay were 2 (range: 0.2–66) and 7 days (3.0–121.0), respectively. At 2 years, New York Heart Association class improved in 65.7%, effective orifice area was 1.6 ± 0.5 cm2; mean gradient was 10.1 ± 4.3 mmHg; and paravalvular leak was none/trivial in 94.5%, mild in 4.9%, moderate in 0.5% and severe in 0.0%. One-year actuarial freedom from all-cause mortality for isolated AVR and for all patients was 98.2% and 97.6%, respectively. Two-year actuarial freedom from mortality in these groups was 95.3% and 94.3%, respectively.CONCLUSIONSThese data demonstrate excellent early safety and effectiveness of aortic valve replacement with a novel bioprosthetic tissue (RESILIA™).Clinical trial registrationclinicaltrials.gov: NCT01757665.

      First page: 440
      Abstract: AbstractOBJECTIVESSevere calcification in the mitral valve annulus is a challenging problem during mitral valve surgery. We describe our experience with mitral valve replacement in severely calcified mitral valve without decalcification of the annulus.METHODSBetween April 2001 and July 2011, 61 patients underwent mitral valve replacement with severe mitral annulus calcification without decalcification of the annulus. This retrospective study was performed to assess the surgical and the long-term postoperative outcomes in this group.RESULTSThe mean age of the patients was 75.2 ± 9.2 years. Twenty-four patients (53%) were in New York Heart Association Class III/IV. Twenty-six patients (58%) had good left ventricular function. Mean logistic EuroSCORE was 8.75. Isolated mitral valve replacement was performed in 12 patients (27%). Coronary artery bypass grafting was done in 13 patients (29%). In-hospital mortality was 4.9% (3 patients). Postoperative morbidity included re-exploration for bleeding in 3 patients (7%) and transient renal impairment in 10 patients (22%). Three patients required intra-aortic balloon pump (7%) for low cardiac output syndrome. Seven patients (16%) required permanent pacemaker, and 1 patient (2%) had thromboembolic event. The 1-year survival was 93.3%, and the 5-year survival was 78.8%. The mean echocardiography follow-up was 40 months. There was no paravalvular leak detected in any patient in the long-term follow-up. None of the patients had valve-related reoperation.CONCLUSIONSMitral valve replacement without annular decalcification in severely calcified mitral valve annulus is a safe and an effective approach and has good long-term outcome.

      Abstract: AbstractOBJECTIVESTo examine differences among participating countries in baseline characteristics, clinical practice, medication strategies and outcomes of patients randomized to coronary artery bypass grafting and percutaneous coronary intervention in the SYNTAX trial.METHODSIn SYNTAX, centres in 18 different countries enrolled 1800 patients, of which 8 countries enrolled ≥80 patients, what was projected to be a large enough sample size to be included in the analysis. Baseline characteristics, practice patterns and clinical outcomes were compared between the USA (n = 245), the UK (n = 267), Italy (n = 197), France (n = 208), Germany (n = 179), Netherlands (n = 148), Belgium (n = 91) and Hungary (n = 83). The remaining patients from other participating countries were pooled together (n = 382).RESULTSFive-year results demonstrated significantly different outcomes between countries. After adjustment, percutaneous coronary intervention patients in France had lower rates of major adverse cardiac and cerebrovascular events [hazard ratio (HR) = 0.60, 95% confidence interval (CI) 0.37–0.98], while the incidence of repeat revascularization was higher in Hungary (HR = 1.89, 95% CI 1.14–3.42). Coronary artery bypass grafting showed the lowest rate of repeat revascularization in the UK (HR = 0.32, 95% CI 0.12–0.85). There were numerous differences in the risk profile of patients between participating countries, as well as marked differences in surgical practice across countries in the use of blood cardioplegia (range 3.1–89.0%; P < 0.001), bilateral internal mammary artery usage (range 7.8–68.2%; P < 0.001) and off-pump procedures (range 3.9–44.4%; P < 0.001). Variation was also found for percutaneous coronary intervention in the number of implanted stents (range 4.0 ± 2.3 to 6.1 ± 2.6; P < 0.001) as well as for the entire stents length (range 69.0 ± 45.1 to 124.1 ± 60.9; P < 0.001). Remarkable differences were observed in the prescription of post-coronary artery bypass grafting medication in terms of acetylsalicylic acid (range 79.6–95.0%; P = 0.004), thienopyridine (6.8–31.1%; P < 0.001) and statins (41.3–89.1%; P < 0.001).CONCLUSIONSPatient characteristics and clinical patterns are significantly different between countries, resulting in significantly different 5-year outcomes. This article presents specific data that can further improve outcomes in each country.Clinical Trials RegistryNCT00114972.

  • Impact of dual antiplatelet therapy after coronary artery bypass surgery
           on 1-year outcomes in the Arterial Revascularization Trial †
    • Authors: Benedetto U; Altman DG, Gerry S, et al.
      First page: 456
      Abstract: AbstractOBJECTIVESThere is still little evidence to boldport routine dual antiplatelet therapy (DAPT) with P2Y12 antagonists following coronary artery bypass grafting (CABG). The Arterial Revascularization Trial (ART) was designed to compare 10-year survival after bilateral versus single internal thoracic artery grafting. We aimed to get insights into the effect of DAPT (with clopidogrel) following CABG on 1-year outcomes by performing a post hoc ART analysis.METHODSAmong patients enrolled in the ART (n = 3102), 609 (21%) and 2308 (79%) were discharged on DAPT or aspirin alone, respectively. The primary end-point was the incidence of major adverse cerebrovascular and cardiac events (MACCE) at 1 year including cardiac death, myocardial infarction, cerebrovascular accident and reintervention; safety end-point was bleeding requiring hospitalization. Propensity score (PS) matching was used to create comparable groups.RESULTSAmong 609 PS-matched pairs, MACCE occurred in 34 (5.6%) and 34 (5.6%) in the DAPT and aspirin alone groups, respectively, with no significant difference between the 2 groups [hazard ratio (HR) 0.97, 95% confidence interval (CI) 0.59–1.59; P = 0.90]. Only 188 (31%) subjects completed 1 year of DAPT, and in this subgroup, MACCE rate was 5.8% (HR 1.11, 95% CI 0.53–2.30; P = 0.78). In the overall sample, bleeding rate was higher in DAPT group (2.3% vs 1.1%; P = 0.02), although this difference was no longer significant after matching (2.3% vs 1.8%; P = 0.54).CONCLUSIONSBased on these findings, when compared with aspirin alone, DAPT with clopidogrel prescribed at discharge was not associated with a significant reduction of adverse cardiac and cerebrovascular events at 1 year following CABG.

           drug-eluting stents in three-vessel coronary artery disease: a propensity
           score matched analysis †

      First page: 462
      Abstract: AbstractOBJECTIVESCompared with percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) appears to be a promising revascularization strategy for multivessel coronary disease. Trials comparing these treatments have not used second-generation drug-eluting stents (2nd DES). We conducted a retrospective evaluation of both treatments using a propensity score-matched analysis (PSMA).METHODSA total of 537 patients with three-vessel with/without left-main-trunk coronary artery disease underwent CABG (n = 239) or primary PCI using 2nd DES (298) at a single institution. PSMA resulted in 168 matched pairs. For both treatments, Kaplan–Meier analysis and Cox regression were used to compare all-cause mortality, cardiac death, myocardial infarction (MI), stroke rates and target-vessel revascularization (TVR).RESULTSThe CABG group included sicker patients with renal dysfunction, peripheral vascular disease, low ejection fraction and current smokers than those in the PCI group. After PSMA, both groups were well matched in all parameters. Mean follow-up (months) was 32 in CABG and 35 in PCI. In the unmatched patient population, there was no difference in the incidence of all-cause death, cardiac death, MI, or stroke but the incidence of TVR was significantly higher in the PCI group [hazard ratio (HR) 4.63; 95% confidence interval (95% CI) 2.43–8.82; P < 0.001] and, after PSMA, the incidence of all-cause death (HR 2.71; 95% CI 1.14–6.46; P = 0.019) and TVR (HR 9.0; 95% CI 2.73–29.67; P < 0.001) was significantly higher in the PCI group than in the CABG group.CONCLUSIONSIn patients with three-vessel coronary artery disease, CABG is associated with better survival and less revascularization than PCI using 2nd DES at mid-term results.

    • Authors: Rankin J; Lerner DJ, Braid-Forbes M, et al.
      First page: 471
      Abstract: AbstractOBJECTIVESWhile surgical ablation (SA) for persistent atrial fibrillation (AF) can reduce recurrence of AF, its impact on longitudinal survival and health-care costs remains controversial. This study defines the clinical outcomes and costs associated with SA in patients with prior AF undergoing coronary artery bypass grafting (CABG).METHODSA total of 3745 Medicare beneficiaries with prior AF who underwent CABG in 2013 were divided into 2 groups: those with and those without concomitant SA. Risk-adjusted early (0–90 days) and late (91–364 days) postoperative outcomes and inpatient costs were compared.RESULTSSA was performed in 17% of CABG patients with prior AF. Preoperative characteristics favoured patients with SA: emergent presentation (15% vs 22%), heart failure in the 2 weeks prior to CABG (31% vs 36%), chronic lung disease (27% vs 33%) and renal failure (4% vs 7%) (all P < 0.05). Risk-adjusted operative mortality and perioperative stroke rates were similar in the 2 groups. Risk-adjusted survival was similar through 90 days, but significantly better with SA after 90 days [hazard ratio (HR) = 0.58; P = 0.03]. At 1 year, the risk-adjusted incidence of cardiovascular implantable electronic device implantation was greater with SA (HR = 1.20; P = 0.01). Risk-adjusted costs for the CABG admission (HR = 1.11; P < 0.01) and inpatient care through 1 year (HR = 1.06; P = 0.02) were also greater with SA.CONCLUSIONSIn the US Medicare population, SA was performed in 17% of CABG-AF patients in 2013. Operative risks for mortality and stroke did not increase with SA but costs did. Patients receiving SA, however, had significantly better risk-adjusted late survival.

      First page: 479
      Abstract: AbstractOBJECTIVESThis study tested the hypothesis that remote perconditioning offers effective and synergistic cardioprotection to terminal warm blood cardioplegia for prompt ventricular recovery after prolonged cardioplegic arrest in an in vivo piglet model.METHODSTwenty-four piglets were subjected to 120 min of single-dose cardioplegic arrest and were divided into 4 groups according to the mode of reperfusion: control (simple aortic unclamp), remote perconditioning, terminal warm blood cardioplegia or remote perconditioning + terminal warm blood cardioplegia; remote perconditioning (4 cycles of 5-min ischaemia-reperfusion of the lower limb) was applied prior to aortic unclamping. Left ventricular systolic and diastolic functions were assessed by pressure–volume loop analysis at baseline and after 60 min of reperfusion. Biochemical injury was evaluated by plasma troponin T level.RESULTSThe control group showed decreased end-systolic elastance, preload recruitable stroke work and inverse of end-diastolic pressure–volume relationship of 51.3 ± 14.0%, 46.1 ± 22.5% and 34.8 ± 14.9%, respectively. Percentage recovery of end-systolic elastance and preload recruitable stroke work were significantly better with terminal warm blood cardioplegia (with or without remote perconditioning) (end-systolic elastance: 95% confidence interval, 38.6–84.1; preload recruitable stroke work: 95% confidence interval, 0.4–54.3). Percentage recovery of inverse of end-diastolic pressure–volume relationship was significantly better in the remote perconditioning groups (with or without terminal warm blood cardioplegia) (95% confidence interval, 1.6–41.6). No synergistic effects of remote perconditioning and terminal warm blood cardioplegia on troponin T release were noted.CONCLUSIONSRemote perconditioning offers promising synergistic cardioprotection to terminal warm blood cardioplegia, implicating potential clinical benefit by contributing to prompt left ventricular functional recovery during paediatric open-heart surgery.

  • Evaluation of conventional and frozen elephant trunk techniques on spinal
           cord blood flow in an animal model †
    • Authors: Leontyev S; Dieterlen M, Halling M, et al.
      First page: 485
      Abstract: AbstractOBJECTIVESThe treatment of patients with extensive thoracic aortic disease involving the arch and descending aorta is often performed using the frozen elephant trunk technique (FET). Spinal cord blood flow (SCBF) in cervical, thoracic and lumbar sections prior, during and after aortic arch surgery were compared in conventional elephant trunk (cET) and FET technique in a pig model.METHODSGerman Landrace pigs (75–85 kg) underwent aortic arch surgery using the FET (n = 8) or cET (n = 8) techniques. The E-vita Open hybrid stent graft was applied in all FET animals. Regional SCBF was measured 4 times: (i) before cardiopulmonary bypass, (ii) after 1 h, (iii) after 3 h, and (iv) after 6 h of reperfusion using fluorescence microspheres. Spinal cord segments were examined histopathologically and by immunohistochemistry.RESULTSSCBF in FET decreased significantly from 0.13 ± 0.03 to 0.05 ± 0.02 ml/min/g after 1 h (P = 0.047). While at 3 h of reperfusion, SCBF increased and was comparable to baseline (0.09 ± 0.01 ml/min/g), beyond this time SCBF decreased again (0.05 ± 0.02 ml/min/g). A similar trend was found for SCBF in the cET group (baseline: 0.16 ± 0.04 ml/min/g, 1 h reperfusion: 0.02 ± 0.01 ml/min/g, 3 h reperfusion: 0.03 ± 0.01 ml/min/g and 6 h reperfusion: 0.02 ± 0.01 ml/min/g, P = 0.019). Cervical, thoracic and lumbar SCBF were also comparable in both groups. Histological analyses of spinal cord showed no differences in necrosis between cET and FET, while no differences were found for hypoxia-inducible factor-1α and apoptosis-inducing factor. In contrast, oxidative stress and caspase-induced apoptosis were higher in cET versus FET.CONCLUSIONSThe SCBF changed significantly during extensive aortic arch surgery with circulatory arrest and moderate hypothermia, but such changes were comparable between the FET and cET groups. The implantation of hybrid stent graft did not influence SCBF in thoracic and lumbar segments of the spinal cord. The immunohistological examination showed no differences between cET and FET regarding ischaemic damage and hypoxia-induced effects in spinal cord segments.

      Abstract: AbstractOBJECTIVESHypothermic circulatory arrest is essential to aortic arch surgery, although consensus regarding optimal cerebral protection strategy remains lacking. We evaluated the current use and comparative effectiveness of hypothermia/cerebral perfusion (CP) strategies in aortic arch surgery.METHODSUsing the Society of Thoracic Surgeons Database, cases of aortic arch surgery with hypothermic circulatory arrest from 2011 to 2014 were categorized by hypothermia strategy—deep/profound (D/P; ≤20°C), low–moderate (L-M; 20.1–24°C), and high–moderate (H-M; 24.1–28°C)—and CP strategy—no CP, antegrade (ACP), retrograde (RCP) or both ACP/RCP. After adjusting for potential confounders, strategies were compared by composite end-point (operative mortality or neurologic complication).RESULTSOf the 12 521 aortic arch repairs with hypothermic circulatory arrest, the most common combined strategies were straight D/P without CP (25%), D/P + RCP (16%) and D/P + ACP (14%). Overall rates of the primary end-point, operative mortality and stroke were 23%, 12% and 8%, respectively. Among the 7 most common strategies, the 2 not utilizing CP (straight D/P and straight L-M) appeared inferior, associated with significantly higher risk of the composite end-point (odds ratio: 1.6; P < 0.01); there was no significant difference in composite outcome between the remaining strategies (D/P + ACP, D/P + RCP, L-M + ACP, L-M + RCP and H-M + ACP).CONCLUSIONSIn a comparative effectiveness study of cerebral protection strategies for aortic arch repair, strategies without adjunctive CP, including the most commonly utilized strategy of straight D/P hypothermia, appeared inferior to those utilizing CP. There was no clearly superior strategy among remaining techniques, and randomized trials are needed to define best practice.

      Abstract: AbstractOBJECTIVESTo evaluate the results of reoperation on descending thoracic and thoracoabdominal aneurysms.METHODSSixty-nine consecutive patients undergoing reoperative aneurysm repair (20 descending thoracic and 49 thoracoabdominal) were compared to 602 contemporary primary repairs. Propensity matching was used to reduce observable differences in preoperative characteristics.RESULTSThe reoperation group was younger (60.2 vs 65.3 years, P = 0.005) and less were extent I or II (28.6% vs 76%, P < 0.001). In the reoperation group, 82.6% were repaired with clamp-and-sew, 14.5% circulatory arrest and 2.9% partial bypass versus the primary surgery group 62.1%, 8.1% and 29.7%, respectively (P < 0.001). In the reoperation versus primary surgery group, respectively, spinal drainage was used in 73.9% vs 83.7% (P = 0.05), intercostal reimplantation in 11.6% vs 44.2% (P < 0.001), and cold renal perfusion in 36.2% vs 19.8% (P = 0.001). Operative mortality was comparable (8.7% vs 5.3% primary, P = 0.25) but the reoperative extent I subgroup had higher mortality (20% vs 3.1%; P = 0.04). Incidence of major complications was comparable (stroke 0 vs 0.9%, tracheostomy 5.8% vs 8%, renal failure 7.2% vs 5%, spinal cord injury 4.3% vs 2.7%; P > 0.05 for all variables), with the exception of myocardial infarction (2.9% vs 0.5%, P = 0.028). Five-year survival was 57.6% in reoperations and 58% in the primary surgery group (P = 0.878). No differences in the in-hospital and follow-up outcomes were found in the propensity matched comparison.CONCLUSIONSReoperative repair of descending thoracic and thoracoabdominal aneurysms can be safely performed with reasonable in-hospital and follow-up outcomes compared to primary aneurysm repair.

      First page: 508
      Abstract: AbstractOBJECTIVESIn DeBakey Type I acute aortic dissection, the frozen elephant trunk technique is used for the combined treatment of both the proximal and distal thoracic aorta. Anatomical characteristics of the distal aorta and their impact on false lumen (FL) thrombosis and aortic remodelling were analysed in this study.METHODSSufficient pre-, postoperative, and at least one 1-year follow-up computed tomography data sets were available for 63 of 94 patients treated with the frozen elephant trunk for Type I acute aortic dissection between March 2005 and March 2015. Aortic remodelling and FL thrombosis quotients were calculated volumetrically at the stent graft level (A), from A to the coeliac trunk (B) and from B to the bifurcation (C) and were correlated with the number and size of entry tears and aortic branches arising from the FL (exits) in each segment.RESULTSPositive or stable remodelling was found in Segments A (94%), B (64%) and C (54%), and the FL thrombosis quotient was 98% in A, 68% in B and 39% in C within the first year. FL thrombosis correlated negatively with the total size of the entry (P<0.001) and the number of exits (P<0.001) and positively with the number of true-lumen branches (P<0.001). The exit number was a risk factor for FL patency and a predictor of negative remodelling.CONCLUSIONSUsing frozen elephant trunk technique to treat Type I acute aortic dissection facilitates positive or stable remodelling in nearly all patients at the stent graft level and distally in two-thirds of the patients. FL thrombosis and aortic remodelling are negatively influenced by the number of exits. New endovascular concepts aiming at reducing the number of exits may prevent negative remodelling.

      Abstract: AbstractOBJECTIVESVideo-assisted thoracoscopic sublobar resection of ultra-small, non-visible and non-palpable pulmonary lesions is challenging. The purpose of this study was to explore an alternative and efficient method for the localization of pulmonary lesions using electromagnetic navigation bronchoscopy (ENB).METHODSBetween May 2015 and April 2016, 24 consecutive patients with 30 pulmonary peripheral lesions underwent video-assisted thoracoscopic surgery for sublobar resection in our hospital. ENB was performed before surgery to guide a catheter adjacent to the target lesion, and fibrin sealant mixed with methylene blue was injected.RESULTSAll patients underwent ENB with pleural dye marking followed immediately by surgery. No surgical complications occurred. The median size of the nodules was 11.0 mm (range, 6–19 mm). The median navigation time was 18.0 min (range, 13 to 120 min), and the average interval between dye marking and thoracic surgery was 22.1 min (range, 15–40 min). In all cases, the target pulmonary parenchyma was stained and had tactile sense with few complications. All lesions were fully excised, and pathological examination confirmed the accuracy of the dye staining.CONCLUSIONSFibrin sealant mixed with methylene blue injection with ENB guidance is a new effective approach to localize even ultra-small and non-palpable pulmonary lesions. The visible staining and tactile sensation of this method may allow more rapid intraoperative identification of lesions.

      Abstract: AbstractOBJECTIVESSince survival after postoperative non-small-cell lung cancer (NSCLC) recurrence is extremely poor, the long-term post-recurrence outcomes are not well understood. The purpose of this study was to evaluate the long-term post-recurrence outcomes and clarify who are possibly ‘cured’ in recent clinical practice.METHODSWe reviewed the medical records of 635 patients who developed postoperative recurrence until 2012 after R0 resection for pathological Stage IA–IIIA NSCLC between 1993 and 2006. Factors associated with post-recurrence survival (PRS) and the characteristics of the long-term (≥5 years) survivors were analysed retrospectively.RESULTSThe 5-year PRS rate of all 635 patients was 13%. Multivariable analysis revealed that female [hazard ratio (HR) = 0.78], adenocarcinoma (HR = 0.77), locoregional (only) recurrence (HR = 0.59) and longer recurrence-free survival (HR = 0.99) were favourably associated with PRS. A total of 51 patients achieved 5-year PRS; however, 32 (63%) were cancer-bearing patients in their fifth post-recurrent year who were mainly treated by epidermal growth factor receptor–tyrosine kinase inhibitor (EGFR-TKI). Subsequent PRS curves for cancer-controlled and cancer-bearing groups were different (8-year PRS: 94% vs 31%, P = 0.003). Among 19 cancer-controlled patients in their fifth post-recurrent year, 17 (89%) patients initially received radical local therapy for their recurrence.CONCLUSIONSTwo-thirds of 5-year survivors after postoperative NSCLC recurrence had a cancer-bearing status and showed deteriorated subsequent survival. Curability of postoperative NSCLC recurrence should be evaluated in terms of the ‘cancer-controlled’ status, and ‘cured’ population is included in the patients who are ‘cancer controlled’ at the fifth post-recurrent year.

  • Relationship between onset of spontaneous pneumothorax and weather
           conditions
    • Authors: Mishina T; Watanabe A, Miyajima M, et al.
      First page: 529
      Abstract: AbstractOBJECTIVESSpontaneous pneumothorax (SP) results from the rupture of blebs or bullae. It has been suggested that changes in weather conditions may trigger the onset of SP. Our aim was to examine the association between the onset of primary SP with weather changes in the general population in Sapporo, Japan.METHODSFrom January 2008 through September 2013, 345 consecutive cases with a diagnosis of primary SP were reviewed. All cases of primary SP developed in the area within 40 km from the Sapporo District Meteorological Observatory. Climatic measurements were obtained from the Observatory, which included 1-h readings of weather conditions. Logistic regression model was used to obtain predicted risks for the onset of SP with respect to weather conditions.RESULTSSP occurred significantly when the atmospheric pressure decreased by − 18 hPa or less during 96 h before the survey date (odds ratio = 1.379, P = 0.026), when the pressure increased by 15 hPa or more during 72 h before the survey date (odds ratio = 1.095, P = 0.007) and when maximum fluctuation in atmospheric pressure over 22 hPa was observed during 96 h before the survey date (odds ratio = 1.519, P = 0.001). Other weather conditions, including the presence of thunderstorms, were not significantly correlated with the onset of pneumothorax.CONCLUSIONSChanges in atmospheric pressure influence the onset of SP. Future studies on the relationship between the onset of SP and weather conditions on days other than before the onset and with large number of patients may enable us to predict the onset of SP in various regions and weather conditions.

  • Comparison of plethysmographic and helium dilution lung volumes in
           patients with a giant emphysematous bulla as selection criteria for
           endobronchial valve implant †
    • Authors: Fiorelli A; Scaramuzzi R, Pierdiluca M, et al.
      First page: 534
      Abstract: AbstractOBJECTIVESTo assess whether the difference in lung volume measured with plethysmography and with the helium dilution technique could differentiate an open from a closed bulla in patients with a giant emphysematous bulla and could be used as a selection criterion for the positioning of an endobronchial valve.METHODSWe reviewed the data of 27 consecutive patients with a giant emphysematous bulla undergoing treatment with an endobronchial valve. In addition to standard functional and radiological examinations, total lung capacity and residual volume were measured with the plethysmographic and helium dilution technique. We divided the patients into 2 groups, the collapse or the no-collapse group, depending on whether the bulla collapsed or not after the valves were put in position. We statistically evaluated the intergroup differences in lung volume and outcome.RESULTSIn the no-collapse group (n = 6), the baseline plethysmographic values were significantly higher than the helium dilution volumes, including total lung capacity (188 ± 14 vs 145 ± 13, P = 0.0007) and residual volume (156 ± 156 vs 115 ± 15, P = 0.001). In the collapse group, there was no significant difference in lung volumes measured with the 2 methods. A difference in total lung capacity of ≤ 13% and in residual volume of ≤ 25% measured with the 2 methods predicted the collapse of the bulla with a success rate of 83% and 84%, respectively. Only the collapse group showed significant improvement in functional data.CONCLUSIONSSimilar values in lung volumes measured with the 2 methods support the hypothesis that the bulla communicates with the airway (open bulla) and thus is likely to collapse when the endobronchial valve is implanted. Further studies are needed to validate our model.

  • Surgical resection after neoadjuvant chemoradiation for oesophageal
           adenocarcinoma: what is the optimal timing'
    • Authors: Ranney DN; Mulvihill MS, Yerokun BA, et al.
      First page: 543
      Abstract: AbstractOBJECTIVESThe purpose of this study was to determine the optimal timing of surgical resection of oesophageal adenocarcinoma following neoadjuvant chemoradiotherapy (nCRT).METHODSnCRT before resection of oesophageal adenocarcinoma yields improved overall and progression-free survival. Despite the wide acceptance of tri-modal therapy, the optimal timing of surgical resection after nCRT is not well defined and existing studies are limited. Adults with Stage II/III oesophageal adenocarcinoma undergoing nCRT before surgery were identified from the National Cancer Database. Multivariable analysis using restricted cubic splines was used to identify an inflection point in clinical outcomes as a function of time between nCRT and surgery, dividing the cohort into short- and long-interval treatment groups, which were then compared. Adjusted rates of survival and margin status were compared between groups using multivariable analysis.RESULTSAmong 2444 patients, restricted cubic splines identified an inflection point at 56 days, dividing our cohort into 1533 short-interval and 911 long-interval patients. Long-interval patients had a higher adjusted incidence of pathologic downstaging (odds ratio 1.38, confidence interval 1.02–1.85, P = 0.04) but no difference in margin positivity compared with short-interval patients (odds ratio 0.91, confidence interval 0.56–1.47, P = 0.69). Worse overall survival was noted in the long-interval subgroup (hazard ratio 1.44, confidence interval 1.22–1.71, P < 0.001), but 30-day postoperative mortality was not statistically different (odds ratio 1.56, confidence interval 0.9–2.72, P = 0.12).CONCLUSIONSRestricted cubic splines provides an objective mechanism to more accurately delineate optimum timing between nCRT and surgical resection. A time interval of 56 days represents an interval where increased pathologic downstaging is balanced by decreased overall survival.

  • The use of extracorporeal membrane oxygenation in neonates with severe
           congenital diaphragmatic hernia: a 26-year experience from a tertiary
           centre †
    • Authors: Vaja R; Bakr A, Sharkey A, et al.
      First page: 552
      Abstract: AbstractOBJECTIVESNeonates with severe congenital diaphragmatic hernia requiring extracorporeal membrane oxygenation (ECMO) have a high rate of mortality. There is controversy regarding optimal time of surgical intervention. We present our data over a 26-year period.METHODSWe analysed data from our Extracorporeal Life Support Organization registry forms between 1989 and 2015, in order to determine the factors affecting survival outcome for repair of congenital diaphragmatic hernia with ECMO as a bridge to surgery and/or recovery.RESULTSNinety-eight neonates with congenital diaphragmatic hernia requiring ECMO were identified. In-hospital mortality was 32%. The overall mortality (47.9%) in our study was seen up to 7 months, after this point there was no mortality. There was no difference in survival in patients repaired using pre-, intra- or postoperative ECMO (P = 0.65). Requiring haemofiltration at any point was significantly associated with reduced survival [hazard ratio 2.7 (95% confidence interval 1.5–4.9); P = 0.01] as was the presence of neurological complications [hazard ratio 3.7 (95% confidence interval 1.6–8.5); P = 0.003]. Age, Apgar score, mode of delivery, side, associated cardiac comorbidities, pH, partial pressure of carbon dioxide, partial pressure of oxygen, oxygen saturations, bicarbonate, high-frequency oscillatory ventilation, mode of ECMO, inhaled nitric oxide, pulmonary complications and bleeding were not associated with any survival difference.CONCLUSIONSWe believe that all neonates with severe diaphragmatic hernia should be given the option of ECMO if clinically indicated. Provided these patients survive the initial postoperative period, they go on to have a sustained survival benefit. Long-term cost analysis and morbidity need to be taken into account to determine the true effect of ECMO on congenital diaphragmatic hernia.

  • Neuro-developmental outcome in single-ventricle patients: is the Norwood
           procedure a risk factor'
    • Authors: Rotermann I; Logoteta J, Falta J, et al.
      First page: 558
      Abstract: AbstractOBJECTIVESComplex neonatal surgery is considered a risk factor for neuro-developmental impairment in single-ventricle patients. Neuro-developmental outcome was compared between preschool-aged Fontan patients who underwent a Norwood procedure and single-ventricle patients not requiring neonatal surgery with cardiopulmonary bypass.METHODSVerbal, performance and full-scale intelligence quotient (IQ) were evaluated with the Wechsler Preschool and Primary Scale of Intelligence. Cognitive functions were assessed with the German ‘Kognitiver Entwicklungstest für das Kindergartenalter’ (KET-KID). Risk factors for impaired neuro-development were evaluated.RESULTSNeuro-developmental assessment was completed in 95 patients (Norwood: n = 69; non-Norwood: n = 26). Median (interquartile range) IQ and KET-KID scores were in the normal range. Except for verbal KET-KID, scores did not differ between Norwood and non-Norwood patients (verbal IQ: 98 (86–105) vs 93 (85–102), P = 0.312; performance IQ: 91 (86–100) vs 96 (86–100), P = 0.932; full-scale IQ: 93 (86–101) vs 89 (84–98), P = 0.314; KET-KID verbal: 48 (17–72) vs 25 (2–54), P = 0.020; KET-KID non-verbal: 33 (18–62) vs 45 (15–54), P = 0.771; KET-KID global: 42 (14–65) vs 28 (6–63), P = 0.208). Full-scale IQ was below average (<85 points) in 14 (20%) Norwood and 9 (35%) non-Norwood cases (P = 0.181). Global KET-KID was below average (<16th percentile) in 19 (28%) and 10 (38%) patients (P = 0.326). Smaller head circumference z-score and complications before neonatal surgery were independently associated with lower scores.CONCLUSIONSNeuro-developmental outcome of preschool-aged Fontan patients was in the normal range. The Norwood procedure was not a risk factor for neuro-developmental impairment. Preoperative condition and patient-related factors were more important determinants than variables related to surgical palliation.

  • Mid-term outcomes in unbalanced complete atrioventricular septal defect:
           role of biventricular conversion from single-ventricle palliation †
    • Authors: Nathan M; Emani S, IJsselhof R, et al.
      First page: 565
      Abstract: AbstractOBJECTIVESManagement strategy for unbalanced complete atrioventricular septal defects (CASVSDs) includes single-ventricle (SV) palliation and primary or staged biventricular (BiV) repair. More recently, BiV conversion (BiVC) from SV palliation and staged BiV recruitment (BiVR) have also been advocated. This study assesses mid-term outcomes in patients with unbalanced CASVSDs according to management strategy.METHODSConsecutive patients with unbalanced CASVSDs who underwent surgery at a tertiary care centre from January 2000 to February 2016 with institutional review board approval. The index surgery was defined as the first palliation procedure for the SV group, a BiV repair for the BiV repair group and conversion or the first procedure for recruitment for the BiVC/BiVR group. Kaplan–Meier and Cox regression were used for time-to-event analysis of death/transplant and unplanned reinterventions that occurred after the index surgery.RESULTSThere were 212 patients: 82 (38.7%) had SV palliation, 67 (31.6%) had BiV repair and 63 (29.7%) had BiVC/BiVR, respectively; 50 patients had undergone a successful BiVC. There were 93 (43.9%) boys; 51 (24%) patients had Down syndrome; and 101 (48%) patients had heterotaxy. In the entire cohort, there were 40 (18.9%) deaths, 110 (51.9%) reinterventions, 82 (38.7%) surgical reinterventions and 70 (33%) catheter reinterventions, with some patients having more than 1 reintervention. Median length of follow-up was 35 (range 1–192) months. The BiVC/BiVR group had a transplant-free survival benefit similar to that of the primary BiV repair group compared with the SV group. The BiV repair group needed fewer catheter-based reinterventions compared with the SV and BiVC/BiVR groups.CONCLUSIONSBiVC or BiVR from an SV pathway can be achieved with low rates of mortality and morbidity in patients with unbalanced CASVSDs.

           4-decade perspective
    • Authors: Raissadati A; Nieminen H, Sairanen H, et al.
      First page: 573
      Abstract: AbstractOBJECTIVESWe analysed nationwide early and late results after the Mustard, Senning and arterial switch operation.METHODSWe included all paediatric patients (<18 years) who underwent a Senning, a Mustard or an arterial switch operation for transposition of the great arteries from 1968 to 2009 in Finland. Data were obtained retrospectively from a paediatric cardiac surgical database and population data from the Finnish national registry.RESULTSEarly mortality (<30 days) was 11% after Mustard and 5% after Senning operation, while the rate decreased from 19% during 1976–1999 to 2% during 2000–2009 for arterial switch patients (P < 0.0001). The 43-year survival rate was 75% [95% confidence interval (CI) 70–80%] for all patients and 97% (95% CI 94–98%) for the general population. Late survival improved during later eras, with a 10-year survival of 96% (95% CI 92–99%) for those operated during 2000–2009 vs 81% (95% CI 74–88%) in the 1990s (hazard ratio 3.7, 95% CI 1.4–9.6, P = 0.008). Twenty-year survival rates (without 30-day mortality) after arterial switch operation, Mustard and Senning were 97% (95% CI 95–100%), 78% (95% CI 68–87%) and 84% (95% CI 77–90%), respectively. No late sudden deaths or fatal heart failures occurred after the arterial switch operation.CONCLUSIONSOutcome after surgery for transposition of the great arteries has improved, mostly due to the arterial switch operation but also due to improvements in perioperative care and follow-up. Operative deaths after the arterial switch operation have diminished, and no late sudden deaths or fatal heart failures occurred during the first 25–30 years after the procedure.

  • Contemporary results of aortic valve repair for congenital disease:
           lessons for management and staged strategy †
    • Authors: Vergnat M; Asfour B, Arenz C, et al.
      First page: 581
      Abstract: AbstractOBJECTIVESAny aortic valve (AoV) operation in children (repair, Ross or mechanical replacement) is a palliation and reinterventions are frequent. AoV repair is a temporary solution primarily aimed at allowing the patient to grow to an age when more definitive solutions are available. We retrospectively analysed AoV repair effectiveness across the whole age spectrum of children, excluding neonates and AoV disease secondary to congenital heart disease.METHODSFrom 2003 to 2015, 193 consecutive patients were included. The mean age was 9.2 ± 6.9 years (22% <1 year); 86 (45%) had a preceding balloon valvuloplasty. The indications for the procedure were stenotic (n = 123; 64%), regurgitant (n = 63; 33%) or combined (n = 7; 4%) disease. The procedures performed were commissurotomy shaving (n = 74; 38%), leaflet replacement (n = 78; 40%), leaflet extension (n = 21; 11%) and neocommissure creation (n = 21; 11%). Post-repair geometry was tricuspid in 137 (71%) patients.RESULTSThe 10-year survival rate was 97.1%. Freedom from reoperation and replacement at 7 years was, respectively, 57% (95% confidence interval, 47–66) and 68% (95% confidence interval, 59–76). In multivariate analysis, balloon dilatation before 6 months, the absence of a developed commissure, a non-tricuspid post-repair geometry and cross-clamp duration were predictors for reoperation and replacement. After a mean follow-up period of 5.1 ± 3.0 years, 145 (75%) patients had a preserved native valve, with undisturbed valve function (peak gradient <40 mmHg, regurgitation ≤mild) in 113 (58%).CONCLUSIONSAortic valve repair in children is safe and effective in delaying the timing for more definitive solution. Surgical strategy should be individualized according to the age of the patient. Avoidance of early balloon dilatation and aiming for a tricuspid post-repair arrangement may improve outcomes.

    • Authors: Lenoir M; Pontailler M, Gaudin R, et al.
      First page: 590
      Abstract: AbstractOBJECTIVESTo determine the early, intermediate and long-term outcomes of pulmonary atresia with ventricular septal defect (PA/VSD) Types I, II and III initially palliated by a right ventricle to pulmonary artery (RVPA) connection.METHODSWe performed a retrospective study from 2000 to 2014 that included 109 patients with PA/VSD who had undergone an RVPA connection (tetralogy of Fallot and PA/VSD Type IV excluded). The end-points of this strategy were adequate pulmonary artery tree post-palliation, second palliation, biventricular repair, right ventricular pressure post-biventricular repair and late reoperation. Mean follow-up was 5.4 years (1 day to 14–78 years).RESULTSEarly mortality after an RVPA connection was 2.7% (3 of 109). The interstage mortality rate was 6.6% (7 of 106). Eighty-four (77%) patients had a biventricular repair and 8 patients (7%) are awaiting repair. Overall survival was 90% at 1 year and 81% at 10 years. The RVPA connection allowed significant growth of the native pulmonary artery with a Nakata index of 101 mm2/m2 before the RVPA connection and 274 mm2/m2 after (P = 0.001). Twenty-nine reinterventions for restrictive pulmonary blood flow have been done (9 before 2 months and 20 after 2 months). Of the 84 patients who had a repair, 22 patients (26%) initially had a right ventricular pressure greater than 40 mmHg. Twenty-eight patients (33%) required late reoperation.CONCLUSIONSHospital deaths after the RVPA connection were low. The procedure allowed good growth of the native pulmonary artery. Biventricular repair was possible in a large number of cases. The late morbidity rate remains significant. Early reinterventions could be avoided by appropriate calibration. This technique appears to be suitable for any type of PA/VSD with central pulmonary arteries.

  • Collapsed stent graft and severe malperfusion 2 years after
           endovascular aortic repair
    • Authors: Goto Y; Hosoba S, Ogawa S, et al.
      First page: 599
      Abstract: AbstractLate collapsing of a stent graft is an extremely rare event, with one existing report describing this phenomenon. A 65-year-old man with a history of endovascular aortic repair for an abdominal aortic aneurysm presented with paraplegia and bilateral lower limb ischaemia. Contrast-enhanced computed tomography showed a dissection of the descending thoracic aorta and a collapsed stent graft, resulting in bilateral lower limb ischaemia. Subsequent axillo-bifemoral bypass resolved his lower extremity functions. The patient required haemodialysis due to acute kidney failure. The follow-up computed tomography scan demonstrated re-expansion of the collapsed stent graft, and his renal function recovered. The case highlights the rare manifestation of late stent collapse and subsequent re-expansion of the collapsed stent and restoration of visceral and lower extremity perfusions following axillo-bifemoral bypass.

      First page: 601
      Abstract: AbstractPrimary chondrosarcoma of the trachea is an extremely rare non-epithelial neoplasm with only few cases published in the literature. We present a rare case of tracheal chondrosarcoma with extensive extraluminal growth. We operated a patient with obstructive tumour of the upper third of the trachea via partial sternotomy. Before surgery, a Hanarostent was put into the trachea to treat a life-threatening stenosis. Postoperative period was uneventful. We discuss the incidence, clinical presentation and treatment options in patients with rare tracheal tumours. In some cases, a multidisciplinary approach (endoscopic intervention followed by surgical resection) is an effective treatment tool.

  • Ex vivo lung perfusion; this idea deserves testing
    • Authors: Mohamed MA.
      First page: 607
      Abstract: The levels of certain cytokines can predict not only the transplant outcome and the functionality of the graft after transplantation but also the transplant decision during ex vivo lung perfusion (EVLP). Combining the perfusate’s levels of interleukin (IL)-1β and IL8 can predict the graft performance during EVLP, the decision of transplantation and the oxygenation capacity after transplantation [1, 2]. On the other side, such finding could be the clue for the prevention and/or controlling of the hazards to which the graft is exposed.
