  • Clinical outcomes in patients after extracorporeal membrane oxygenation
           support for post-cardiotomy cardiogenic shock: a single-centre experience
           of 92 cases †
    • Authors: Guihaire J; Dang Van S, Rouze S, et al.
      Abstract: AbstractOBJECTIVESPost-cardiotomy cardiogenic shock is a major concern in cardiac surgery. We reviewed our experience of extracorporeal membrane oxygenation (ECMO) as temporary circulatory support in post-cardiotomy cardiogenic shock.METHODSBetween January 2005 and December 2014, adult patients implanted with ECMO after cardiac surgical procedures were included. Indications for ECMO were failure to be withdrawn from cardiopulmonary bypass or refractory cardiogenic shock occurring during postoperative Days 1 and 2. Patients’ characteristics and outcomes were prospectively collected in a local ECMO database.RESULTSNinety-two patients, median age of 63 years (17–83 years), were supported by ECMO following valvular surgery (66%), acute aortic dissection (10%) and coronary artery bypass grafting (9%). A total of 37% were combined surgical procedures, 24% were redo procedures and 33% were emergent procedures. The median duration of ECMO support was 6 days (1–28 days). The weaning rate from mechanical support was 48%. Overall 1-month and 6-month survival rates were, respectively, 42% and 39%. Survivors were younger (57 vs 63 years old, P = 0.02) and had a higher preoperative left ventricular ejection fraction (52.5 vs 44.1%, P = 0.017). There was a trend for lower serum creatinine levels and total bilirubin rates in the survivors’ group 24 h after initiation of ECMO (respectively, 162 vs 212 µmol/l, P = 0.06; 25.3 vs 54.2 mg/dl, P = 0.08). Valvular surgery and peak lactic acid serum level were associated with poor outcomes. The mean health-related quality of life EuroQoL scale was 68 ± 16/100 at 2 years.CONCLUSIONSRefractory cardiogenic shock requiring ECMO was most frequently observed after redo valvular surgery in the present study. The overall 6-month survival rate was 39% after ECMO support for post-cardiotomy cardiogenic shock with acceptable health-related quality of life. Improved kidney and liver functions after 24 h of support were associated with favourable outcomes.

  • Early versus late pulmonary valve replacement in patients with
           transannular patch-repaired tetralogy of Fallot
    • Authors: Dobbels B; Herregods M, Troost E, et al.
      Abstract: AbstractOBJECTIVESAlthough the effects of pulmonary regurgitation after tetralogy of Fallot repair are detrimental, timing of pulmonary valve replacement (PVR) is unclear. Our goal was to evaluate the midterm efficacy and safety of early PVR.METHODSPatients with tetralogy of Fallot who underwent repair from 1962 to 2015 were included from the local database. Statistical analyses compared patients who underwent early PVR (age ≤16 years), late PVR and no PVR. The timing of the intervention was compared for efficacy—all-cause mortality and the combined end-point of all-cause mortality, ventricular tachycardia and defibrillator implantation—and for safety—the combined end-point of 1-year postoperative mortality after PVR, endocarditis and reintervention. Echocardiographic and electrocardiographic data at the last follow-up examination were compared across the 3 groups.RESULTSTwo hundred seventy-three patients (age 21 ± 5 years; 52% female) were included. The mean follow-up was 24 (95% confidence interval 22.7–26.2) years; the observed median was 21 years (interquartile range 11–31). No significant difference in survival was found between the early PVR (n = 106; 39%), the late PVR (n = 47; 17%) and the no PVR groups (n = 120; 44%) (P = 0.990). No significant difference in the combined efficacy end-point was noted between patients who underwent early PVR compared with patients who underwent late PVR (P = 0.247). Worse event-free survival for the 3-point safety end-point was observed after early PVR (P < 0.001). Right ventricular morphology (P < 0.001) and function (P < 0.001) were better preserved in the patient group that underwent PVR before the age of 16 years.CONCLUSIONSAs expected, PVR-related morbidity was higher in patients who underwent early PVR but the midterm outcome was similar. Nevertheless, better preservation of right ventricular morphology and function in the early PVR group might result in better long-term survival.

  • Mitral valve repair or replacement in hypertrophic obstructive
           cardiomyopathy: a prospective randomized study †
    • Authors: Bogachev-Prokophiev A; Afanasyev A, Zheleznev S, et al.
      Abstract: AbstractOBJECTIVESThe optimal surgical strategy for concomitant mitral valve intervention during myectomy remains controversial. The purpose of this study was to compare the results of mitral valve replacement versus repair in patients with hypertrophic obstructive cardiomyopathy and severe mitral regurgitation.METHODSBetween 2010 and 2013, a total of 88 patients with hypertrophic obstructive cardiomyopathy and severe mitral regurgitation were randomly assigned to undergo either mitral valve replacement or repair in addition to extended myectomy.RESULTSThree patients from the repair group were switched to mitral valve replacement after repair failure. There was 1 early death (2.4%) in the replacement group. The resting left ventricular outflow tract gradient was reduced from 89.1 ± 20.4 to 18.3 ± 5.7 mmHg (P < 0.001) and from 96.6 ± 28.1 to 14.7 ± 5.9 mmHg (P < 0.001) in the replacement and repair groups, respectively; there was no significant difference between the groups (P = 0.458). At 2-year follow-up, overall survival was 87.2 ± 4.9% and 96.7 ± 3.3% (P = 0.034); freedom from sudden cardiac death was 95.6 ± 3.1% and 96.7 ± 3.3% (P = 0.615); and freedom from thromboembolic events was 91.2 ± 4.2% and 100%, respectively (P = 0.026).CONCLUSIONSBoth mitral valve repair and valve replacement in addition to extended myectomy are effective methods of surgical treatment in patients with hypertrophic obstructive cardiomyopathy who have severe mitral regurgitation. The benefits of mitral valve repair are better overall survival and a lower rate of thromboembolic events.Clinical trial registrationClinicalTrials.gov: NCT02054221.

  • Single-stage repair for multiple muscular septal defects: a single-centre
           experience across 16 years
    • Authors: Shetty V; Shetty D, Punnen J, et al.
      Abstract: AbstractOBJECTIVESMultiple muscular ventricular septal defects (VSDs) are surgically challenging and its management remains controversial. We present a technique of surgical repair for muscular VSDs, which includes surgical exposure and detection of these defects and has excellent clinical outcomes.METHODSWe have analysed consecutive patients who underwent surgical repair of isolated multiple muscular VSDs under cardiopulmonary bypass over a 16-year period (from January 2001 to November 2016) in a single centre from the southern part of India. These defects were accessed through the right atrium in most cases and closed directly; completeness of closure was confirmed by pressurizing the left ventricle with blood cardioplegia. There were no haemodynamically significant residual VSDs following repair.RESULTSOne hundred and two patients with an average time of follow-up of 4.1 years (1 month–12 years) were included. The mean age of our patients at the time of operation was 23.5 months (3 months–22 years) with a mean weight of 7.9 kg (2–55 kg). The mean cardiopulmonary bypass and cross-clamp time was 118.8 ± 39.2 min (mean ± SD) and 76.5 ± 29.4 min (mean ± SD), respectively. There were 10 (9.8%) hospital deaths and 3 late deaths in the entire study group. Permanent pacemaker was implanted in 2 patients. Seventy patients could be followed up after discharge. Postoperative pulmonary artery pressure was normal in 52% of the patients, mild-to-moderate hypertension in 27% and severe in 7% of the patients. The ejection fraction was >60% among the survivors, and there were no reoperations or reinterventions.CONCLUSIONSThis surgical approach to multiple muscular VSDs is safe and effective with minimal risk of complete heart block and diminution of ventricular function.

  • Characteristics and prognostic factors of node-negative non-small cell
           lung cancer larger than 5 cm †
    • Authors: Cho S; Kim K, Jheon S.
      Abstract: AbstractOBJECTIVESIn the 7th edition of the tumour, node and metastasis staging system, a primary tumour size larger than 5 cm was shifted to Stage II. Therefore, we aimed to evaluate the characteristics and prognostic factors of node-negative non-small cell lung cancer (NSCLC) larger than 5 cm.METHODSWe included 109 patients who underwent curative resection and had pathologically confirmed node-negative NSCLC >5 cm (Group 1). We compared the clinicopathological characteristics and prognosis of these patients with 85 patients with node-positive NSCLC >5 cm (Group 2) and 383 patients who had node-positive NSCLC ≤5 cm (Group 3).RESULTSCompared with Group 2, old age and absence of lymphovascular invasion was significantly more common in Group 1. Compared with Group 3, frequency of non-adenocarcinoma type and visceral pleural invasion were significantly higher in Group 1; however, the frequency of lymphovascular invasion was higher in Group 3. A Cox proportional hazards model showed that the maximized standardized uptake value and visceral pleural invasion was a statistically worse prognostic factor. Compared with Group 2, Group 1 showed significantly longer overall survival; however, there was no difference in recurrence-free survival. Compared with Group 3, there was no significant difference in recurrence-free survival and overall survival. In Group 1, recurrence in the contralateral lung was the most common recurrence pattern, and there was no metastasis in the mediastinal lymph nodes.CONCLUSIONSPatients with node-negative NSCLC >5 cm had a lower incidence of lymphovascular invasion and a more common contralateral recurrence than patients with node-positive NSCLC, and visceral pleural invasion was identified as independent prognostic factors.

  • Transfemoral, transapical and transcatheter aortic valve implantation and
           surgical aortic valve replacement: a meta-analysis of direct and adjusted
           indirect comparisons of early and mid-term deaths
    • Authors: Ando T; Takagi H, Grines CL.
      Abstract: AbstractClinical outcomes of transfemoral–transcatheter aortic valve implantation (TF-TAVI) versus surgical aortic valve replacement (SAVR) or transapical (TA)-TAVI are limited to a few randomized clinical trials (RCTs). Because previous meta-analyses only included a limited number of adjusted studies or several non-adjusted studies, our goal was to compare and summarize the outcomes of TF-TAVI vs SAVR and TF-TAVI vs TA-TAVI exclusively with the RCT and propensity-matched cohort studies with direct and adjusted indirect comparisons to reach more precise conclusions. We hypothesized that TF-TAVI would offer surgical candidates a better outcome compared with SAVR and TA-TAVI because of its potential for fewer myocardial injuries. A literature search was conducted through PUBMED and EMBASE through June 2016. Only RCTs and propensity-matched cohort studies were included. A direct meta-analysis of TF-TAVI vs SAVR, TA-TAVI vs SAVR and TF-TAVI vs TA-TAVI was conducted. Then, the effect size of an indirect meta-analysis was calculated from the direct meta-analysis. The effect sizes of direct and indirect meta-analyses were then combined. A random-effects model was used to calculate the hazards ratio and the odds ratio with 95% confidence intervals. Early (in-hospital or 30 days) and mid-term (≥1 year) all-cause mortality rates were assessed. Our search resulted in 4 RCTs (n = 2319) and 14 propensity-matched cohort (n = 7217) studies with 9536 patients of whom 3471, 1769 and 4296 received TF, TA and SAVR, respectively. Direct meta-analyses and combined direct and indirect meta-analyses of early and mid-term deaths with TF-TAVI and SAVR were similar. Early deaths with TF-TAVI vs TA-TAVI were comparable in direct meta-analyses (odds ratio 0.64, P = 0.35) and direct and indirect meta-analyses combined (odds ratio 0.73, P = 0.24). Mid-term deaths with TF-TAVI vs TA-TAVI were increased (hazard ratio 0.83, P = 0.07) in a direct meta-analysis and became significant after addition of the indirect meta-analysis (hazard ratio 0.78, 95% confidence interval 0.67–0.92, P = 0.003). In conclusion, TF-TAVI was associated with similar early and mid-term deaths compared with SAVR. The number of early deaths was not significantly different between TF-TAVI and TA-TAVI, whereas there were fewer mid-term deaths with TF-TAVI than with TA-TAVI.

  • Percutaneous cannulation for cardiopulmonary bypass in minimally invasive
           surgery is associated with reduced groin complications
    • Authors: Moschovas A; Amorim PA, Nold M, et al.
      Abstract: AbstractOBJECTIVESFemoral cutdown is standard in most centres if groin cannulation is used for cardiopulmonary bypass in minimally invasive cardiac surgery (MICS). Arterial closure devices (ACDs) allow placement of larger cannulas percutaneously, but its benefit in MICS is unclear. We assessed our results with percutaneous groin cannulation using ACDs in comparison with conventional surgical access in patients undergoing MICS.METHODSWe reviewed 445 consecutive patients having undergone MICS between October 2010 and March 2015. Of those, 92 (21%) were performed with conventional surgical access to the groin vessels and 353 (79%) with the use of ACDs.RESULTSOperative risk was higher in the ACD group [logistic EuroSCORE 7.9% (SD: 8.1) vs 10.6% (SD: 12.3); P = 0.010]. The use of ACDs significantly reduced operation time [193 min (SD: 43.8) vs 173 min (SD: 47.1); P < 0.001] and hospital stay [Cutdown: median 9 days (8, 14); ACD: median 9 days (7, 12), P = 0.040] without affecting the time to full mobilization. The incidence of any complication was significantly lower in the ACD group (2.3% vs 8.7%; P = 0.007). Complications with conventional cannulation consisted of lymphatic fistulae (n = 4), wound infections (n = 2), stenosis (n = 1) and haematoma (n = 1). In the ACD group, there were local dissections (n = 2) and stenoses (n = 3). There was 1 haematoma in both groups. There were 2 vascular injuries in the ACD group (n = 2), leading to conversion to surgical access.CONCLUSIONSPercutaneous groin cannulation using ACDs for establishing cardiopulmonary bypass in minimally invasive valve surgery significantly reduces groin complications, operation time and hospital stay. However, the remaining complications are mainly of vascular nature versus wound infection and lymph fistulae with cutdown.

  • The affordability of minimally invasive procedures in major lung
           resection: a prospective study
    • Authors: Gondé H; Laurent M, Gillibert A, et al.
      Abstract: AbstractOBJECTIVESMinimally invasive procedures are used for the surgical treatment of lung cancer. Two techniques are proposed: video-assisted thoracic surgery or robotic-assisted thoracic surgery. Our goal was to study the economic impact of our long-standing program for minimally invasive procedures for major lung resection.METHODSWe conducted a single-centre, 1-year prospective cost study. Patients who underwent lobectomy or segmentectomy were included. Patient characteristics and perioperative outcomes were collected. Medical supply expenses based on the microcosting method and capital depreciation were estimated. Total cost was evaluated using a national French database.RESULTSOne hundred twelve patients were included, 57 with and 55 without robotic assistance. More segmentectomies were performed with robotic assistance. The median length of stay was 5 days for robotic-assisted and 6 days for video-assisted procedures (P = 0.13). The duration of median chest drains (4 days, P = 0.36) and of operating room time (255 min, P = 0.55) was not significantly different between the groups. The overall conversion rate to thoracotomy was 9%, significantly higher in the video-assisted group than in the robotic group (16% vs 2%, P = 0.008). No difference was observed in postoperative complications. The cost of most robotic-assisted procedures ranged from €10 000 to €12 000 (median €10 972) and that of most video-assisted procedures ranged from €8 000 to €10 000 (median €9 637) (P = 0.007); median medical supply expenses were €3 236 and €2 818, respectively (P = 0.004). The overall mean cost of minimally invasive techniques (€11 759) was significantly lower than the mean French cost of lung resection surgical procedures (€13 424) (P = 0.001).CONCLUSIONSThe cost at our centre of performing minimally invasive surgical procedures appeared lower than the cost nationwide. Robotic-assisted thoracic surgery demonstrated acceptable additional costs for a long-standing program.

  • The impact of multidisciplinary care on early morbidity and mortality
           after heart transplantation
    • Authors: Schmidhauser M; Regamey J, Pilon N, et al.
      Abstract: AbstractOBJECTIVESThe impact of multidisciplinary care on outcome after heart transplantation (HTx) remains unclear.METHODSThis retrospective study investigates the impact of multidisciplinary care on the primary end point 1-year all-cause mortality (ACM) and the secondary end point mean acute cellular rejection (ACR) grade within the first postoperative year.RESULTSThis study includes a total 140 HTx recipients (median age: 53.5 years; males: 80%; donor/recipient gender mismatch: 38.3%; mean length of in-hospital stay: 34 days; mean donor age: 41 years). Multidisciplinary care was implemented in 2008, 66 HTx recipients had operation in 2000–07 and 74 patients had HTx thereafter (2008–14). Non-ischaemic dilated cardiomyopathy was more prevalent in HTx recipients of 2000–07 (63.6 vs 43.2%; P = 0.024). Pre-transplant mechanical circulatory support was more frequent in 2008–14 (9.1 vs 24.3%; P = 0.030). Groups were not different for pre-transplant cardiovascular risk factors or other comorbidity, invasive haemodynamics or echocardiographic parameters. In-hospital and 1-year ACM were numerically lower in 2008–14 (16.2 vs 22.2%; 18.9% vs 25.8%; P = 0.47/0.47, respectively). In 2000–07, pre-transplant weight and diabetes mellitus predicted in-hospital ACM (odds ratio −0.14, P = 0.02; OR 5.24, P = 0.01, respectively) while post-transplant length of in-hospital stay was related with in-hospital ACM (odds ratio −0.10; P = 0.016) and 1-year ACM (odds ratio −0.07; P = 0.007). In 2000-07, the mean grade of ACR within the first postoperative year was higher (0.65 vs 0.20; P < 0.0001) and ≥moderate ACR was associated with in-hospital mortality (χ2 = 3.92; P = 0.048).CONCLUSIONSMultidisciplinary care in HTx compensates post-transplant risk associated with pre-transplant disease and has beneficial impact on the incidence of ACR and ACR-associated early mortality.

  • Clinical implications of hypothermic ventricular fibrillation versus
           beating-heart technique during cardiopulmonary bypass for pulmonary valve
           replacement in patients with repaired tetralogy of Fallot
    • Authors: Lee J; Lee J, Shin J, et al.
      Abstract: AbstractOBJECTIVESThis study aimed to compare the effects of hypothermic ventricular fibrillation and beating-heart techniques during cardiopulmonary bypass (CPB) on postoperative outcomes after simple pulmonary valve replacement in patients with repaired tetralogy of Fallot (TOF).METHODSWe retrospectively reviewed the data of 47 patients with repaired tetralogy of Fallot at a single institution, who received pulmonary valve replacement under the ventricular fibrillation or beating-heart technique without cardioplegic cardiac arrest during CPB between January 2005 and April 2015.RESULTSThe patients were divided into fibrillation (n = 32) and beating-heart (n = 15) groups. On comparing these groups, the fibrillation group had a larger sinotubular junction (27.1 ± 4.6 vs 22.1 ± 2.4 mm), had a longer operation duration (396 ± 108 vs 345 ± 57 min), required more postoperative transfusions (2.1 ± 2.6 vs 5.0 ± 6.3 units) and had a higher vasoactive–inotropic score at intensive care unit admission (8.0 vs 10, all P < 0.05). Echocardiographic data indicated that the systolic internal diameter of the left ventricle was larger in the fibrillation group than in the beating-heart group immediately after surgery and at the 1-year follow-up. Major adverse cardiac events occurred in 3 cases, all from the fibrillation group. Among 7 patients from the fibrillation group with transoesophageal echocardiography data during CPB, 6 had fully opened aortic valves during fibrillation, causing flooding into the left ventricle and left ventricle distension.CONCLUSIONSThe postoperative outcomes are worse with the ventricular fibrillation technique than with the beating-heart technique during CPB for pulmonary valve replacement in patients with repaired tetralogy of Fallot.

  • Computational fluid dynamics characterization of pulsatile flow in central
           and Sano shunts connected to the pulmonary arteries: importance of graft
           angulation on shear stress-induced, platelet-mediated thrombosis
    • Authors: Ascuitto R; Ross-Ascuitto N, Guillot M, et al.
      Abstract: AbstractOBJECTIVESCentral (aorta) and Sano (right ventricle)-to-pulmonary artery (PA) shunts, palliative operations for infants with complex heart defects, can develop life-threatening thrombosis. We employed computational fluid dynamics (CFD) to study pulsatile flow in these shunts, with the goal to identify haemodynamic characteristics conducive to thrombus formation.METHODSCFD, using the finite volume method with cardiac catheterization data, and computer simulations, based on angiography, were employed to determine flow-velocity field, wall shear stress (WSS) profile and oscillatory shear index (OSI).RESULTSAt prominent angulation, in central shunts (4 and 3.5 mm), WSS reached 245 and 123 (Pascal-Pa), peak systole and 137 and 46 Pa, end diastole; and, in Sano shunts (5 and 6 mm), WSS attained 203 and 133 Pa, peak systole and 1.6 and 1.5 Pa, end diastole. Counter-rotating flow vortices augmented WSS. These high WSSs can promote platelet aggregation, leading to thrombus formation. The OSIs averaged 0.39, indicative of multidirectional shearing forces. Shunt burden was assessed by averaging WSS, over its luminal area and the cardiac cycle. For the central shunts, these WSSs were 73.0 and 67.2 Pa; whereas, for the Sano shunts, 34.9 and 19.6 Pa. For modified Blalock-Taussig shunts (4 and 3.5 mm), the averaged WSSs were significantly lower at 26.0 and 27.5 Pa, respectively.CONCLUSIONSCFD modelling is an important tool to determine blood flow behaviour in shunts. Graft angulation presents a risk for shear stress-induced, platelet- mediated thrombosis, which is more likely to occur in elongated central than in Sano shunts.

  • Surgical resection for advanced lung cancer using the hemi-clamshell
           approach
    • Authors: Shintani Y; Kanzaki R, Kawamura T, et al.
      Abstract: AbstractOBJECTIVESThe hemi-clamshell (HCS) approach consists of partial sternotomy with antero-lateral thoracotomy. This study evaluated the utilities and outcomes of the HCS approach in advanced lung cancer patients.METHODSWe retrospectively investigated 45 patients who underwent surgery for advanced lung cancer via the HCS procedure between 2000 and 2014, the indications for surgery being tumour invasion extending to the aorta arch in 5, descending aorta in 9, main pulmonary artery in 5, superior vena cava in 6, right or left atrium in 4, apical thoracic dome in 7 patients and mediastinal lymphadenopathy for left-sided lung cancer in 12. Preoperative chemo-radiation induction therapy was given to 33 of these patients.RESULTSWe performed 34 lobectomies, including 8 sleeve lobectomies, 10 pneumonectomies and 1 wedge resection of the lung. Cardiovascular reconstruction of the aortic arch was performed in 3, descending aorta in 4, subclavian arteries in 4, superior vena cava in 5, atrial wall in 4 and pulmonary artery in 12 patients with some overlap. En bloc chest wall resection was performed in 7 patients. Lymphadenectomy in the pre-tracheal and subcarinal areas was routinely performed. Forty-two operations (93%) were complete resections. No postoperative mortalities occurred and the 5-year survival rate for all patients was 53%.CONCLUSIONSThe HCS approach is suitable for advanced lung cancer, including invasion of mediastinal structures, the apical dome and mediastinal lymph nodes. It provides a wide view of the mediastinum and apex of the chest, and safe access to the thoracic great vessels, resulting in better long-term survival rates.

  • Lymph node metastases in thymic malignancies: a Chinese Alliance for
           Research in Thymomas retrospective database analysis †
    • Authors: Gu Z; Wei Y, Fu J, et al.
      Abstract: AbstractOBJECTIVESLymphatic involvement is believed to be relatively rare in thymic epithelial tumours. The incidence and prognostic significance of nodal metastases are still unclear. The goal of this study was to define the incidence and prognostic relevance of nodal metastasis in patients with thymic epithelial tumours, using a nationwide retrospective database of the Chinese Alliance for Research in Thymomas.METHODSPatients who underwent upfront surgical resection without preoperative therapy were enrolled for the study. The International Thymic Malignancies Interest Group proposal of a new staging system for thymic epithelial tumours was used to redefine the pathological stage. The incidence of nodal metastasis and its relationship with clinicopathological characteristics and its impact on survival were examined accordingly.RESULTSA total of 1617 patients were enrolled in this study. Lymph node metastasis was identified in 35 patients (2.2%). No nodal involvement was found in type A, AB or B1 thymomas. The incidence of nodal metastasis in thymoma (B2/B3) and thymic carcinoma was 1.3% and 7.9%, respectively, and it was most commonly seen in patients with neuroendocrine thymic tumours (16.7%, P < 0.001). According to the primary tumour invasion stage, incidences of nodal metastasis were 0.2% in T1, 6.9% in T2, 8.5% in T3 and 7.4% in T4 tumours (P < 0.001). Gender, pleural or distant metastasis and resection status were also correlated with nodal metastasis (P < 0.05) in univariable analysis. Multivariable analysis revealed that patients with non-thymoma histological characteristics (P < 0.001) and tumours in non-T1 stage (P < 0.001) had significantly greater risk of developing nodal metastasis. The overall survival of patients without nodal metastasis was significantly higher than that of patients with nodal involvement (P < 0.001). Disease-free survival of patients after R0 resection without nodal metastasis was also significantly higher than those with nodal metastasis (P < 0.001). On multivariable analysis, overall survival was significantly associated with histology of the tumour (P = 0.019) and complete resection (P = 0.047), and there was a trend towards significance (P = 0.052) in the association between overall survival and nodal involvement.CONCLUSIONSLymph node metastasis in low-grade, early stage thymic tumours is a rare phenomenon. However, it is not uncommon in tumours with a higher stage or a higher histological grade, especially in neuroendocrine thymic tumours. Nodal involvement as well as tumour invasion and histological grade may denote worse prognosis. Lymph node dissection may be warranted in selected high-risk patients.

  • Risk factors for in-hospital shunt thrombosis and mortality in patients
           weighing less than 3 kg with functionally univentricular heart
           undergoing a modified Blalock–Taussig shunt †
    • Authors: Chittithavorn V; Duangpakdee P, Rergkliang C, et al.
      Abstract: AbstractOBJECTIVESTo determine the association between several perioperative variables and in-hospital shunt thrombosis and mortality in patients weighing less than 3 kg with functional univentricular heart (UVH) who underwent modified Blalock–Taussig shunt.METHODSBetween January 2006 and February 2016, 85 patients who weighed less than 3 kg with functional UVH and underwent modified Blalock–Taussig shunt were reviewed. In-hospital shunt thrombosis and mortality were the primary outcomes. The associations between perioperative variables and outcomes were assessed with univariate and multivariate analyses.RESULTSIn-hospital shunt thrombosis was 14% (12 of 85). Hospital mortality was 18% (15 of 85), which resulted in an 82% discharge survival rate. Shunt thrombosis was significantly associated with in-hospital mortality (odds ratio 18.9, 95% confidence interval 4.5–78.9). There were no statistically significant associations between weight, specific diagnosis of functional UVH and shunt thrombosis or mortality. Multivariate analysis identified delayed initiation of anticoagulant (P < 0.01) and postoperative cardiac arrest (P < 0.01) as risk factors of shunt thrombosis, while intraoperative bradycardia (P < 0.01), high postoperative haemoglobin (P = 0.03) and shunt thrombosis (P < 0.01) were risk factors for hospital mortality.CONCLUSIONSIn this high-risk group of patients who weighed less than 3 kg with functional UVH and who underwent modified Blalock–Taussig shunt, in-hospital mortality was strongly associated with the occurrence of shunt thrombosis. Our study highlighted the perioperative variables of delayed postoperative initiation of anticoagulant, cardiac arrest and the occurrence of intraoperative bradycardia that were significant risk factors for shunt thrombosis and mortality. Achieving better quality of perioperative care potentially improves outcomes.

  • Systematic short-term pulmonary rehabilitation before lung cancer
           lobectomy: a randomized trial
    • Authors: Lai Y; Su J, Qiu P, et al.
      Abstract: AbstractOBJECTIVESThe goal of this study was to assess the impact of a preoperative 1-week, systematic, high-intensity inpatient exercise regimen on patients with lung cancer who had risk factors for postoperative pulmonary complications (PPCs).METHODSWe conducted a randomized controlled trial with 101 subjects of a preoperative, 7-day systematic, integrated, high-intensity pulmonary exercise regimen. The control group received standard preoperative care. We analysed the occurrence of PPCs in both groups as the primary outcome; other outcomes included changes in blood gas, quality of life, peak expiratory flow rate, the 6-min walk distance and others.RESULTSThe 6-min walk distance showed an increase of 22.9 ± 25.9 m in the intervention group compared with 4.2 ± 9.2 m in the control group, giving a between-group difference of 18.7 m (95% confidence interval: 8.8–28.6; P < 0.001); the peak expiratory flow increased by 25.2 ± 24.6 l/min, compared with 4.2 ± 7.7 l/min (between-group difference: 21.0 m, 95% confidence interval: 7.2–34.8; P = 0.003). The intervention group had a shorter average total (15.6 ± 3.6 vs 17.7 ± 5.3 days, P = 0.023) and postoperative length of stay (6.1 ± 3.0 vs 8.7 ± 4.6 days, P = 0.001) than the control group; the incidence of PPCs (9.8%, 5/51 vs 28.0%, 14/50, P = 0.019) was significantly lower. A multivariable analysis of the risk of PPCs identified short-term rehabilitation intervention to be an independent risk factor (odds ratio = 0.156, 95% confidence interval: 0.037–0.649, P = 0.011).CONCLUSIONSThe study results suggested that a systematic, high-intensity pulmonary exercise programme was a practical strategy when performed preoperatively in patients with lung cancer with risk factors for PPCs.CLINICAL TRIAL REGISTRATIONChiCTR-IOR-16008109.

           angiography study
    • Authors: Riki-Marishani M; Gholoobi A, Sazegar G, et al.
      Abstract: AbstractOBJECTIVESA prosthetic system to repair secondary tricuspid valve regurgitation was developed. The conceptual engineering of the current device is based on 3D segmental remodelling of the tricuspid valve annulus in lieu of reductive annuloplasty. This study was designed to investigate the operational safety of the current prosthetic system with regard to the anatomical integrity of the right coronary artery (RCA) in fresh cadaveric human hearts.METHODSDuring the study period, from January to April 2016, the current prosthetic system was implanted on the tricuspid valve annulus in fresh cadaveric human hearts that met the study’s inclusion criteria. The prepared specimens were investigated via selective coronary angiography of the RCA in the catheterization laboratory. The RCA angiographic anatomies were categorized as normal, distorted, kinked or occluded.RESULTSSixteen specimens underwent implantation of the current prosthetic system. The mean age of the cadaveric human hearts was 43.24 ± 15.79 years, with vehicle accident being the primary cause of death (59%). A dominant RCA was noticed in 62.5% of the specimens. None of the specimens displayed any injury, distortion, kinking or occlusion in the RCA due to the implantation of the prostheses.CONCLUSIONSIn light of the results of the present study, undertaken on fresh cadaveric human heart specimens, the current segmental prosthetic system for 3D remodelling of the tricuspid valve annulus seems to be safe vis-à-vis the anatomical integrity of the RCA. Further in vivo studies are needed to investigate the functional features of the current prosthetic system with a view to addressing the complex pathophysiology of secondary tricuspid valve regurgitation.

  • Can oesophagectomy be performed for patients with oesophageal carcinoma
           and concomitant liver cirrhosis' A retrospective study based on a
           propensity-matched cohort
    • Authors: Wang Z; Deng H, Yang Y, et al.
      Abstract: AbstractOBJECTIVESFor patients with oesophageal carcinoma and concomitant liver cirrhosis, the safety profile and postoperative prognosis of oesophagectomy are not clearly established due to the lack of relevant studies with large sample sizes. Our objective was to explore the surgical indications and postoperative prognosis in patients with oesophageal carcinoma and liver cirrhosis.METHODSA total of 2226 patients with oesophageal carcinoma underwent curative oesophagectomy (37 with liver cirrhosis and 2189 without) in our department from April 2008 to September 2013. Overall, 37 patients with liver cirrhosis (30 Child–Pugh Grade A and 7 Child-Pugh Grade B) and a propensity-matched cohort of 74 patients without cirrhosis were analysed. We compared the rates of postoperative complications and 5-year survival in these 2 groups. In addition, we performed an analysis of any potential risk factors for death, including patient demographic information and of operation performed.RESULTSA higher operative mortality rate was observed in patients with oesophageal carcinoma and liver cirrhosis compared to patients with oesophageal carcinoma but without cirrhosis (11 vs 1%, P = 0.042). Patients with cirrhosis included those with Child–Pugh Grade B (43%), preoperative moderate ascites (100%), a prothrombin time of ≥ 4 s (75%) and greater weight loss. Although the rates of surgical death and postoperative hydrothorax were significantly higher in patients with liver cirrhosis, the rates of other major complications and 5-year overall survival were not significantly different compared to patients without cirrhosis.CONCLUSIONSCurative oesophagectomy is a feasible, beneficial treatment option for patients with oesophageal carcinoma and liver cirrhosis, with a higher perioperative risk but reasonable longer term survival compared to patients without cirrhosis.

  • Systolic anterior motion of the tricuspid valve in a patient with
           hypertrophic obstructive cardiomyopathy
    • Authors: Farag ES; Planken R, Boekholdt S, et al.
      Abstract: AbstractHypertrophic cardiomyopathy is a heterogeneous myocardial disease and is characterized by increased left ventricular wall thickness. Left ventricular outflow tract obstruction occurs in up to 70% of patients and is often caused by systolic anterior motion of the mitral valve, a paradoxical phenomenon in which the anterior mitral valve leaflet is pulled into the left ventricular outflow tract during systole. We present the first case of hypertrophic cardiomyopathy with systolic anterior motion of both the mitral and the tricuspid valves and severe hypertrophy of both ventricles.

  • Anticalcification effect of a combination of decellularization, organic
           solvents and amino acid detoxification on glutaraldehyde-fixed
           xenopericardial heart valves in a large-animal long-term circulatory model
           
    • Authors: Park C; Kim Y, Lee J, et al.
      Abstract: AbstractOBJECTIVESWe aimed to investigate the effect of a combination of anticalcification treatments, which were effective for preventing calcification in a small animal experiment, on glutaraldehyde-fixed xenopericardial valves using a large-animal long-term circulatory model.METHODSValved conduits were made of porcine pericardium as a leaflet and bovine pericardium as a conduit and were implanted into the right ventricular outflow tract of goats under cardiopulmonary bypass. The goats were divided into study (glutaraldehyde + combined anticalcification treatment, n = 6) and control (glutaraldehyde alone, n = 9) groups. Upon euthanization at 1 year, echocardiography and cardiac catheterization were performed. Explanted tissues were microscopically examined and analysed for measuring the calcium content.RESULTSHaemodynamic data were obtained from 3 and 2 goats in the study and control groups, respectively. All valves, except 1, which was limited in motion, were functioning well on echocardiography; pressure gradients across the right ventricular outflow tract were lower in the study group on cardiac catheterization. On gross inspection, all leaflets remained mobile without calcific deposits in the study group, while most leaflets were heavily calcified in the control group. The calcium content in the leaflets remained low (≤4 µg/mg) in the study group. Among the leaflets explanted from goats that survived longer (>3 months), the calcium concentration was higher in the control group than in the study group [15.1 µg/mg (n = 5) vs 2.7 µg/mg (n = 5), respectively; P = 0.008).CONCLUSIONSPorcine pericardial leaflets treated with our anticalcification protocol showed better function and less calcification than those treated with glutaraldehyde alone in the pulmonary position.

  • Thoracoscopic anatomical lung segmentectomy using 3D computed tomography
           simulation without tumour markings for non-palpable and non-visualized
           small lung nodules †
    • Authors: Kato H; Oizumi H, Suzuki J, et al.
      Abstract: AbstractOBJECTIVESAlthough wedge resection can be curative for small lung tumours, tumour marking is sometimes required for resection of non-palpable or visually undetectable lung nodules as a method for identification of tumours. Tumour marking sometimes fails and occasionally causes serious complications. We have performed many thoracoscopic segmentectomies using 3D computed tomography simulation for undetectable small lung tumours without any tumour markings. The aim of this study was to investigate whether thoracoscopic segmentectomy planned with 3D computed tomography simulation could precisely remove non-palpable and visually undetectable tumours.METHODSBetween January 2012 and March 2016, 58 patients underwent thoracoscopic segmentectomy using 3D computed tomography simulation for non-palpable, visually undetectable tumours. Surgical outcomes were evaluated.RESULTSA total of 35, 14 and 9 patients underwent segmentectomy, subsegmentectomy and segmentectomy combined with adjacent subsegmentectomy, respectively. All tumours were correctly resected without tumour marking. The median tumour size and distance from the visceral pleura was 14 ± 5.2 mm (range 5–27 mm) and 11.6 mm (range 1–38.8 mm), respectively. Median values related to the procedures were operative time, 176 min (range 83–370 min); blood loss, 43 ml (range 0–419 ml); duration of chest tube placement, 1 day (range 1–8 days); and postoperative hospital stay, 5 days (range 3–12 days). Two cases were converted to open thoracotomy due to bleeding. Three cases required pleurodesis for pleural fistula. No recurrences occurred during the mean follow-up period of 44.4 months (range 5–53 months).CONCLUSIONSThoracoscopic segmentectomy using 3D computed tomography simulation was feasible and could be performed to resect undetectable tumours with no tumour markings.

  • Results of a multimodal approach for the management of aortic coarctation
           and its complications in adults
    • Authors: Noly P; Legris-Falardeau V, Ibrahim R, et al.
      Abstract: AbstractOBJECTIVESWe aimed to assess the results of various tailored management strategies for adults with coarctation in our centre.METHODSWe reviewed all adults patients treated for aortic caorctation between January 2000 and December 2015 in our institution. The primary end point was a composite of death, perioperative stroke, paraplegia, need for unplanned reoperation or occurrence of pseudoaneurysm during the follow-up. The mean follow-up was 82 ± 5 months.RESULTSSixty-three adults were treated for a native coarctation (n = 34), a recurrent coarctation (n = 14) or aneurysmal complication (n = 15). Mean age of the patients was 42 ± 1.7 years. All but 1 patient with native coarctation (33/34, 97%) and recurrent coarctation (13/14, 93%) underwent endovascular repair and 10 (67%) patients with aneurysmal complications were treated surgically. Freedom from the primary composite end point was 94, 84 and 81% at 1, 5 and 10 years, respectively, without difference between the 3 indication groups (P = 0.96).CONCLUSIONSA tailored management strategy is necessary to provide good results for the treatment of adults with aortic coarctation. Thus, centres that are involved in the care of this complex pathology should be able to propose a multimodal approach, either endovascular or surgical depending on patient’s characteristics and anatomic features.

  • Complicated infective aortic endocarditis: comparison of different
           surgical strategies †
    • Authors: Silaschi M; Nicou N, Deshpande R, et al.
      Abstract: AbstractOBJECTIVESThe choice of substitute during aortic valve replacement for infective endocarditis (IE) is still widely debated. We retrospectively reviewed all patients operated for aortic IE and compared groups according to the complexity of IE and substitutes implanted.METHODSFrom 2000 to 2015, 187 patients were treated using stentless bioprostheses (SBP) as root replacement (n = 30), mechanical prostheses (MP, n = 45) or stented bioprostheses (SP, n = 112) (mean follow-up 4.6 years, survival data 100% complete).RESULTSMP patients were younger (42.5 ± 10.7 vs 57.2 ± 16.9 years [SBP], 59.1 ± 14.1 years [SP], P < 0.01), but rates of intravenous drug use and chronic dialysis were not different. SBP patients more often had root involvement (83.3% vs 33.3% [MP], 25.9% [SP], P < 0.01) and prosthetic valve endocarditis (53.3% vs 6.7% [MP], 12.5% [SP], P < 0.01). In-hospital complications and length of stay were not different. Thirty-day mortality was 13.3% [SBP], 6.7% [MP] and 12.5% [SP] (P = 0.53). Five-year survival tended to be superior in SBP (83.3% vs 77.6% [MP], 67.1% [SP], P = 0.09). In patients with complicated IE (root involvement or prosthetic valve endocarditis, n = 77), SBP had superior long-term survival (86.9% vs 81.3% [MP], 57.2% [SP], PSBP/MP  = 0.07, PSBP/SP = 0.05). No early reinfection (<90 days) occurred in SBP vs 4.4% [MP] and 7.1% [SP] (P = 0.29). Reoperation for late reinfection occurred in 6.7% [SBP] vs 11.1% [MP] and 12.5% [SP] (P = 0.65). Prosthesis failure occurred in 3.3% [SBP] and 1.8% [SP] (P = 0.52).CONCLUSIONSUse of SBP provides favourable outcomes in patients with IE with low rates of reinfection and valve deterioration. It seems to be an optimal device in patients with complex IE.

  • Extra-anatomical bypass in complex and recurrent aortic coarctation and
           hypoplastic arch †
    • Authors: Delmo Walter E; Javier M, Hetzer R.
      Abstract: AbstractOBJECTIVESOur goal was to report the selection schemes, technical variations and long-term outcome of extra-anatomical bypass to correct complex, recurrent aortic coarctation and hypoplastic aortic arch.METHODSBetween 1989 and 2012, 53 patients (mean age 13.2 ± 4.3, median 11.6, range 9–23 years) with complex aortic coarctation (n = 33; long-segment hypoplastic aortic arch in 15), recurrent coarctation (n = 20; anastomosic pseudoaneurysm in 10), underwent correction using extra-anatomical bypass, either with (n = 18: femoral bypass = 13, left heart bypass = 5) or without (n = 35) extracorporeal circulation via a left lateral thoracotomy (n= 48) and combined median sternotomy and median laparotomy (n = 5). The decision to use extracorporeal circulation was based on the anatomical location of the coarctation, the length of the hypoplasia and a history of previous repair. Preoperatively, mean systolic blood pressure was 130 ± 30 mmHg at rest and 180 ± 40 mmHg during exercise, with a mean pressure gradient of 80 ± 11.6 (range 40–120) mmHg.RESULTSVarious extra-anatomical bypass strategies included left subclavian artery to descending aorta (n = 38), ascending aorta to left subclavian artery (n = 3), ascending aorta to descending aorta (n = 4), aortic arch to descending aorta (n = 3) and ascending aorta to abdominal aorta (n = 5). Graft size (median 18, range 10–26, mm) was chosen according to the diameter of the vessel proximal and distal to the planned graft. No operative deaths, paraplegia or abdominal malperfusion occurred. The mean reduction in systolic blood pressure was 60 ± 25 mmHg without pressure gradients. During a mean follow-up of 18.3 ± 3.7 years, there were no reoperations, graft complications or pseudoaneurysm formation on anastomotic sites. Seven (11.6%) patients are on antihypertensive medications. No patient presented with claudication nor did anyone experience orthostatic problems from the steal phenomenon.CONCLUSIONSExtra-anatomical bypass is safe, an effective technique, and achieves satisfactory long-term results.
