      Abstract: We read with great interest the recent publication of Walsh et al. (1) evaluating the possible predictive role of neutrophil-to-lymphocyte ratio (NLR) in the development of postoperative atrial fibrillation (POAF) after non-cardiac thoracic surgery. The authors demonstrated that in contrast to cardiac surgery, in patients undergoing major non-cardiac thoracic surgery, neither preoperative nor early postoperative NLR was associated with the development of POAF (1).

  • Treatment solution for a devilish dilemma by Korteland et al.
    • Authors: Korteland NM; Takkenberg JM, Bogers AC, et al.
      Abstract: The patient’s preference in this case [1] was very clear. He asked for replacement of the mechanical valve by a bioprosthesis, which was driven by symptoms and fear for subdural haematoma persistence/recurrence. After providing detailed information and carefully weighing of the available treatment options, his preference was unchanged and finally accepted by the team. Therefore, it was decided to replace the mechanical valve by a bioprosthesis.

  • Dual source computed tomography based analysis of stent performance, its
           association with valvular calcification and residual aortic regurgitation
           after implantation of a balloon-expandable transcatheter heart valve
    • Authors: Gerstmeyer J; Kütting M, Fujita B, et al.
      Abstract: AbstractOBJECTIVES: The aim of this study was to investigate the mutual influence of valvular calcifications and transcatheter aortic valve stent geometry during and after implantation of a balloon-expandable SAPIEN®/SAPIEN XT® prostheses. Aortic valve calcification has been linked with adverse complications after transcatheter aortic valve implantation (TAVI). However, little is known about the fate of the calcifications after TAVI as well as its influence on transcatheter heart valve geometry.METHODS: Thirty one patients underwent cardiac dual source computed tomography (DSCT) before and after a TAVI with the Edwards SAPIEN/SAPIEN XT® prostheses. Detailed DSCT image analysis was performed with Mimics® and 3Matic® (both Materialise, Leuven, Belgium).RESULTS: Implanted stents reached an average degree of expansion of 84% and achieved good circularity despite the presence of fairly oval native annuli and a heterogeneous degree of valvular calcification. Both, the degree of stent expansion and the degree of stent eccentricity were inversely related to the degree of oversizing, but independent of the degree of valvular calcification and native annular ovality. Visualization of the position of calcific debris before and after TAVI showed that calcifications were shifted upwards and outwards as a consequence of the implantation procedure. The degree of stent eccentricity was related to residual aortic regurgitation grade ≥2.CONCLUSIONS: The SAPIEN®/SAPIEN XT® prostheses achieved good degrees of stent expansion and circularity regardless of the morphology of the landing zone. Increased stent ovality was associated with an elevated risk for aortic regurgitation. The total calcification volume, degree of annular ovality and stent expansion were not associated with residual AR.

  • The activated clotting time in cardiac surgery: should Celite or kaolin be

      Abstract: AbstractOBJECTIVES: Both kaolin- and Celite-activated clotting times (ACT) are used to guide anticoagulation during cardiopulmonary bypass. It is unknown whether these methods lead to similar management procedures for anticoagulation in patients and are thus interchangeable in terms of bias, precision and variability. METHODS: We randomized 97 patients undergoing coronary artery bypass grafting or aortic valve replacement to either kaolin- or Celite-guided anticoagulation. The ACT was measured simultaneously with the other method. We administered 300 IU/kg heparin to obtain initial ACT values greater than 400 s and additional heparin in each group using the minimum value of duplicate measurements according to a predefined protocol. The primary end point was the total heparin dose and the number of heparin supplements.RESULTS: The total heparin dose per patient in the 48 Celite-guided patients was 35 271 ± 12 406 IU with 51 supplements and in the 49 kaolin-guided patients, 35 997 ± 11 540 IU (P = 0.77) with 56 supplements (P = 0.53). Postoperative thrombin generation time, fibrinolytic response time, chest tube loss and transfusion requirements were not different between the two groups. However, the methods differed in individual patients with regard to supplemental heparin (P = 0.002). Bias between methods at baseline was +10.3%, Celite being higher, and changed to a value of −12.9% at 2 h bypass. The coefficient of variation at baseline for individual patients was 2.6 times larger with kaolin than with Celite (P

  • The efficacy and risk of cerebrospinal fluid drainage for thoracoabdominal
           aortic aneurysm repair: a retrospective observational comparison between
           drainage and non-drainage†
    • Authors: Sugiura J; Oshima H, Abe T, et al.
      Abstract: AbstractOBJECTIVES: We reviewed our experiences with thoracoabdominal aortic aneurysm (TAAA) repair to assess the efficacy of cerebrospinal fluid drainage (CSFD) to prevent the neurological deficits and complications associated with CSFD.METHODS: Between 2002 and 2015, 118 patients underwent TAAA repair. Seventy-eight patients underwent CSFD for 2.7 ± 1.1 days after surgery. CSFD was not performed for the other 40 patients due to an urgent situation, chronic disseminated intravascular coagulation or anatomical difficulties.RESULTS: There were 5 in-hospital deaths (4.2%). The neurological complications included paraplegia (n = 14, 11.9%), paraparesis (n = 3, 2.5%), cerebral infarction (n = 11, 9.3%) and intracranial haemorrhage (n = 1, 0.85%), none related to CSFD. The complications related to CSFD included headaches (n = 13, 11.0%), subdural haematoma (which was treated conservatively) (n = 1, 0.85%), a neurological symptom of the bilateral thighs (n = 1, 0.85%), pale haemorrhagic discharge (n = 2, 1.7%) and a fractured catheter (n = 1, 0.85%). Eight patients had paraplegia and 1 patient had paraparesis among the 78 patients who underwent CSFD (9/78, 11.5%); among the 40 patients who did not undergo CSFD, 6 had paraplegia and 2 had paraparesis (8/40, 20.0%). A multivariate analysis demonstrated that CSFD had a significant protective effect for the spinal cord (odds ratio = 0.045, P = 0.007).CONCLUSIONS: CSFD effectively prevented spinal cord dysfunction in TAAA repair. However, some serious complications occurred, including subdural haematoma and a fractured catheter. It is therefore important to recognize both the efficacy and the risks of CSFD in TAAA repair.

  • Surgical repair of ostial obstruction of the coronary artery for
           quadricuspid aortic valve in an infant
    • Authors: Harada T; Fukae K, Ando Y.
      Abstract: AbstractA congenital quadricuspid aortic valve accompanied by ostial obstruction of the left coronary artery is extremely rare and has not yet been reported in an infant. We herein describe an infant with ostial obstruction of the left coronary artery caused by a small left coronary cusp that formed a pouch. The patient’s cardiac function deteriorated due to progressive myocardial ischaemia, and translocation of the ostium of the left coronary artery was performed. Postoperative coronary angiography revealed good filling of the left coronary artery.

  • Transcatheter mitral valve implantation: a percutaneous transapical system
    • Authors: Dai H; Huenges K, Pokorny S, et al.
      Abstract: AbstractOBJECTIVES: Despite recent achievements, implantation of a transcatheter mitral valved stent remains challenging. In this study, we present a different approach for implantation of a percutaneous mitral valved stent.METHODS: Percutaneous transapical access is combined with, respectively, a left-transatrial, right-transatrial/transseptal or transfemoral/transseptal approach for mitral valve stent implantation and secure fixation. The apical fixation and occlusion are ensured with an Amplatzer occluder. This novel approach was tested in 22 porcine hearts in an in vitro setting under the guidance of fluoroscopy (n = 11) and endoscopy (n = 11). The in vitro setup included continuous flushing at 37 °C. We determined the feasibility, time of implantation, stent deployment and stent fixation.RESULTS: Percutaneous mitral valved stent implantation was successful in all cases. Good handling properties and precise positioning were achieved. Time of implantation was comparable in the fluoroscopic and endoscopic groups at 10:41 ± 3:18 and 10:09 ± 2:42 min, respectively. Apical fixation with the occluder was excellent in all 22 cases.CONCLUSIONS: The feasibility of percutaneous mitral valved stent implantation has been demonstrated in preliminary in vitro experiments. Subsequent studies are warranted to determine the efficacy of this minimally invasive catheter-based mitral valved stent implantation.

  • Uniportal thoracoscopic decortication for pleural empyema and the role of
           ultrasonographic preoperative staging†
    • Authors: Bongiolatti S; Voltolini L, Borgianni S, et al.
      Abstract: AbstractOBJECTIVES: The surgical approach to chronic pleural empyema is still controversial. Video-assisted thoracic surgery (VATS) debridement and decortication has shown favourable outcomes, while the uniportal VATS (U-VATS) approach is still anecdotal. We report our experience with ultrasonographic (US) preoperative staging followed by U-VATS decortication for pleural empyema.METHODS: We performed a retrospective analysis of patients who underwent surgical treatment of stage II and stage III pleural empyema from 2012 to 2015. Pre-, intra- and postoperative data were investigated to evaluate outcomes including postoperative complications and disease recurrence. Results were analysed according to preoperative US appearance of pleural space (stages A–E) and surgical approach (thoracotomy vs U-VATS).RESULTS: We performed 30 (47%) uniportal thoracoscopic pleural decortication and 34 (53%) open decortication for empyema in stage II (40%) or III (60%) obtaining a complete debridement and decortication in all patients. In-hospital mortality was zero and overall morbidity was 29%. U-VATS was associated with lower blood loss (118 ±  80 ml vs 247  ±  140 ml P

  • Influence of warfarin therapy on the occurrence of postoperative endoleaks
           and aneurysm sac enlargement after endovascular abdominal aortic aneurysm
    • Authors: Seike Y; Tanaka H, Fukuda T, et al.
      Abstract: AbstractOBJECTIVES: This study aims to determine whether warfarin therapy influences the occurrence of endoleaks or aneurysm sac enlargement after endovascular aortic repair (EVAR).METHODS: A total of 367 patients who underwent EVAR for abdominal aortic aneurysm between 2007 and 2013 were recruited for this study. Satisfactory follow-up data including completed computed tomography scan follow-up for more than 2 years were available for 209 patients, and the mean follow-up time was 37 ± 12 months. Twenty-nine (16%) patients were on warfarin therapy (warfarin group), whereas 180 (84%) patients were not on warfarin therapy (control group).RESULTS: Two- and four-year freedom rates for persistent type II endoleaks were significantly lower in patients of the warfarin group compared with the control group (85 and 49% vs 93 and 91%, respectively; P = 0.0001). Similarly, 2- and 4-year freedom rates for sac enlargement (>5 mm) were significantly lower in patients of the warfarin group compared with the control group (83 and 61% vs 92 and 82%, respectively; P = 0.0036). Using Cox regression analysis, the warfarin therapy was identified to be an independent positive predictor of sac enlargement after EVAR [hazard ratio (HR): 2.4; 95% confidence interval (CI): 1.08–5.40; P = 0.032], together with persistent type II endoleak. Warfarin therapy was also an independent predictor for persistent type II endoleak (HR: 3.7; 95% CI: 1.81–7.41; P < 0.0001) together with the number of patent lumbar arteries.CONCLUSIONS: Results suggested that warfarin therapy was significantly associated with an increased risk for persistent II endoleak and sac enlargement after EVAR.

  • Neurologic outcomes after early surgery for infective endocarditis in
           patients with combined cerebral septic embolism
    • Authors: Kim D; Kim H, Jo K.
      Abstract: AbstractOBJECTIVES: This study followed the results of any development of neurologic outcomes according to the presence or absence of cerebral stroke in infective endocarditis patients after early cardiac surgery. We also analysed the neurologic outcomes regardless of cerebral microbleeds in cerebral embolic patients after cardiac surgery.METHODS: We retrospectively studied 55 patients with left-sided infective endocarditis who underwent early surgery and hospitalization between May 2010 and May 2015. Preoperatively, there were 33 patients in the cerebral embolic group and 22 patients in the non-embolic event group. Among the cerebral embolic patients, 13 patients had additional cerebral microbleeds on brain imaging.RESULTS: After cardiac surgery, intracranial haemorrhage and haemorrhagic complications occurred in 2 patients (9.1%) in the non-embolic group and 5 patients (15.1%) in the embolic group. There was no statistically significant difference in postoperative neurologic problems between the non-embolic group and the embolic group (22.7% vs 30.3%, respectively, P = 0.54). Early mortality was 4.5% in the non-embolic group and 9.1% in the embolic group (P = 1.00). In the cerebral microbleeds combined with septic embolism group, the neurologic problem rate (38.5%) was higher than in the non-cerebral microbleeds group (20.0%), but the difference was not statistically significant.CONCLUSIONS: Our analysis showed that the rate of postoperative neurologic problems was not high in patients with cerebral septic embolism. Despite this, early surgery is not contraindicated in cerebral septic emboli patients. Cerebral microbleeds related to septic embolism were suspected to increase the rate of neurologic problems after cardiac surgery. So, further studies are needed to assess about the influence of cerebral microbleeds in cardiac operation.

  • Early and long-term cognitive outcome after conventional cardiac valve
    • Authors: Knipp SC; Weimar C, Schlamann M, et al.
      Abstract: AbstractOBJECTIVES: Adverse cognitive outcome is well recognized after coronary artery bypass grafting (CABG) while little is known about the extent and duration of decline after cardiac valve surgery. We investigated changes in cognitive function following conventional cardiac valve surgery over up to 4 years.METHODS: Among 36 patients (65.2 ± 9.2 years, 36% women) who received valve surgery, we assessed serial cognitive function with a battery of 11 standardized tests across 3–4 years. Cognitive function was analysed to identify: (1) cognitive decline (i.e. within-patient changes in test scores) and (2) cognitive deficit (i.e. drop of score ≥1 SD in ≥3 tests). Diffusion-weighted magnetic resonance imaging (DW-MRI) was applied pre- and post-procedure to detect ischaemic brain injury. Data were compared to a historical cohort of 39 patients undergoing CABG.RESULTS: After both valve surgery and CABG, a significant decline at discharge was detected in 7 of 11 cognitive tests. The rate of patients with a cognitive deficit after valve surgery vs CABG was 39% vs 56% at discharge, 14% vs 23% at 3 months, and 16% vs 26% at 3–4 years (not significant, [n.s.]). After valve surgery, DW-MRI identified 19 (53%) patients with evidence of 50 new focal ischaemic lesions (CABG: 20 [51%] patients with 42 lesions, n.s.). Cumulative cerebral ischaemic load per patient was not significantly different between the valve surgery group and CABG group (503 ± 485 mm3 vs 415 ± 234 mm3). After correction for multiple potential risk factors in both groups, reduced verbal memory at discharge could be identified as a predictor of long-term cognitive impairment in CABG patients only (P = 0.04). For both the valve surgery and CABG group, no association between cognitive impairment and new ischaemic cerebral lesions was found. CONCLUSIONS: The course of cognitive performance after valve surgery and CABG was similar with early postoperative decline followed by subsequent recovery. Although silent small brain infarcts were present in about half of all patients, they did not impact cognitive performance neither at early nor during long-term follow-up.

  • Predictors and impact of massive bleeding in acute type A aortic
    • Authors: Zindovic I; Sjögren J, Bjursten H, et al.
      Abstract: AbstractOBJECTIVES: Bleeding complications associated with acute type A aortic dissection (aTAAD) are a well-known clinical problem. Here, we evaluated predictors of massive bleeding related to aTAAD and associated surgery and assessed the impact of massive bleeding on complications and survival.METHODS: This retrospective study of 256 patients used Blood Conservation Using Antifibrinolytics in a Randomized Trial (BART) criteria to define massive bleeding, which was met by 66 individuals (Group I) who were compared to the remaining patients (Group II). Multivariable logistic regression was used to identify independent predictors of massive bleeding and in-hospital mortality, Kaplan–Meier estimates for analysis of late survival, and Cox regression analysis to evaluate independent predictors of late mortality.RESULTS: Independent predictors of massive bleeding included symptom duration (odds ratio [OR], 0.974 per hour increment; 95% confidence interval [CI], 0.950–0.999; P = 0.041) and DeBakey type 1 dissection (OR, 2.652; 95% CI, 1.004–7.008; P = 0.049).

      Abstract: AbstractOBJECTIVES: This study aimed to evaluate the influence of preserved additional pulmonary blood flow (APBF) on survival after bidirectional cavopulmonary shunt (BCPS) and completion of Fontan circulation.METHODS: From March 2003 and April 2015, 156 patients with a single ventricle underwent BCPS. After performing propensity score analysis (1:1) for the entire sample, 50 patients with APBF (APBF group) were matched with 50 patients without APBF (no-APBF group).RESULTS: Age (P = 0.90), sex (P = 0.57), weight (P = 0.75), single ventricle morphology (P = 0.87), type of neonatal palliative procedure (P = 0.52), saturation (P = 0.35), ejection fraction (P = 0.90), Nakata index (P = 0.70) and mean pulmonary artery pressure (P = 0.72) were not significantly different between the groups. No significant survival difference was demonstrated (P = 0.54). One and 4-year survival rates were both 89.1% ± 4.6% in the APBF group and 87.2% ± 4.9% and 83.4% ± 5.9%, respectively, in the no-APBF group. There was no significant difference in rates of Fontan completion (P = 0.24), which was achieved in 22 patients from the APBF group (55.0%) and 26 patients from the no-APBF group (65.0%). However, Fontan completion occurred significantly earlier in the no-APBF group (P

  • Coil embolization of left ventricular outflow tract pseudoaneurysms:
           techniques and 5-year results
    • Authors: Ota H; Morita Y, Saiki Y, et al.
      Abstract: AbstractWe present 3 cases of percutaneous coil embolization of left ventricular outflow tract (LVOT) pseudoaneurysms. All patients had a history of repetitive aortic root surgery and/or inflammatory disease. Computed tomography showed pseudoaneurysms connecting the sacs to the LVOT lumen. In each case, a 6-Fr catheter was advanced to the sac by the transfemoral approach. A 0.052-in coil was placed across the tract. There was no significant complications associated with the procedure. No recurrence was evident in any case during the 5-year follow-up. Coil embolization may be an effective treatment for these pseudoaneurysms in patients with complicated histories of aortic root surgery.

  • Mitral implant of the Inovare transcatheter heart valve in failed surgical
           bioprostheses: a novel alternative for valve-in-valve procedures
    • Authors: Gaia D; Braz A, Simonato M, et al.
      Abstract: AbstractOBJECTIVES: Reoperative procedure for the treatment of a failed mitral bioprosthesis is associated with considerable risk. In some cases, mortality is high and might contraindicate the benefit of the procedure. The minimally invasive valve-in-valve (ViV) transcatheter mitral valve implant offers an alternative less-invasive approach, reducing morbidity and mortality. The objective of this paper was to evaluate the mitral ViV approach using the Braile Inovare prosthesis.METHODS: The transcatheter balloon-expandable Braile Inovare prosthesis was used in 12 cases. Procedures were performed in a hybrid operating room, under fluoroscopic and echocardiographic control. Through left minithoracotomy, the prostheses were implanted through the cardiac apex. Serial echocardiographic and clinical examinations were performed. Follow-up varied from 1 to 30 months.RESULTS: A total of 12 transapical mitral ViV procedures were performed. Patients had a mean age of 61.6 ± 9.9 years and 92% were women. Mean logistic EuroSCORE was 20.1%. Successful valve implantation was possible in all cases. In one case, a right lateral thoracotomy was performed for the removal of an embolized prosthesis. There was no operative mortality. Thirty-day mortality was 8.3%. Ejection fraction was preserved after the implant (66.7%; 64.8%; P = 0.3). The mitral gradient showed a significant reduction (11 mmHg; 6 mmHg; P

  • Neutrophil-lymphocyte ratio and risk of atrial fibrillation after thoracic
           surgery †
    • Authors: Walsh KJ; Tan K, Zhang H, et al.
      Abstract: AbstractOBJECTIVES: Postoperative atrial fibrillation (POAF) occurs frequently in patients after noncardiac thoracic surgery and has been associated with increased morbidity and risk of stroke. Recent studies have shown conflicting results on the role of neutrophil-lymphocyte ratio (NLR) and its association with the development of POAF after cardiac surgery. Our goal was to determine whether an association exists between NLR and the incidence of POAF after non-cardiac thoracic surgery.METHODS: Using a database of 259 consecutive patients age 60 or older who had anatomic lung resection or oesophagectomy for oncologic resection, we compared preoperative, postanaesthesia care unit and postoperative day 1 NLR between patients who did and did not develop POAF during their hospitalization using Fisher’s exact test or logistic regression. We also compared NLR in patients who underwent minimally invasive resection versus open surgery.RESULTS: POAF occurred in 50/259 (19%) of patients during their hospitalization. There were no significant differences in NLR between patients who did and did not develop POAF. In a secondary analysis of 180 patients who underwent open anatomic lung resection or oesophagectomy and 79 who underwent minimally invasive anatomic lung resection there was no difference in preoperative or immediate postoperative NLR, or an interaction in terms of odds of developing POAF.CONCLUSIONS: In contrast to cardiac surgery, in patients undergoing major non-cardiac thoracic surgery, we had no evidence to show that either preoperative or early postoperative NLR was associated with the development of POAF.

  • The “basic” approach: a single-centre experience with a cost-reducing
           model for paediatric cardiac extracorporeal membrane oxygenation
    • Authors: Padalino MA; Tessari C, Guariento A, et al.
      Abstract: AbstractOBJECTIVES: Extracorporeal membrane oxygenation (ECMO) is a lifesaving but expensive therapy in terms of financial, technical and human resources. We report our experience with a ‘basic’ ECMO support model, consisting of ECMO initiated and managed without the constant presence of a bedside specialist, to assess safety, clinical outcomes and financial impact on our health system.METHODS: We did a retrospective single-centre study of paediatric cardiac ECMO between January 2001 and March 2014. Outcomes included postimplant complications and survival at weaning and at discharge. We used activity based costing to compare the costs of current basic ECMO with those of a ‘full optional’ dedicated ECMO team (hypothesis 1); ECMO with a bedside nurse and perfusionist (hypothesis 2), and ECMO with a bedside perfusionist (hypothesis 3).RESULTS: Basic cardiac ECMO was required for 121 patients (median age 75 days, median weight 4.4 kg). A total of 107 patients (88%) had congenital heart disease; 37 had univentricular physiology. The median duration of ECMO was 7 days (interquartile range [IQR], 4–15 days). Overall survival at weaning and at 30 days in the neonatal and paediatric age groups was 58.6% and 30.6%, respectively; these results were not significantly different from Extracorporeal Life Support Organization data. Cost analysis revealed a saving of €30 366, €22 144 and €13 837 for each patient on basic ECMO for hypotheses 1, 2 and 3, respectively.CONCLUSIONS: Despite reduced human, technical and economical resources, a basic ECMO model without a bedside specialist was associated with satisfactory survival and lower costs.

  • Does the addition of postoperative radiotherapy to adjuvant chemotherapy
           offer any benefit in patients with non-small cell lung cancer and
           mediastinal lymphadenopathy?
    • Authors: Koulaxouzidis G; Toufektzian L, Ashrafian L, et al.
      Abstract: A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether the addition of postoperative radiotherapy (PORT) to adjuvant chemotherapy offers any benefit in patients undergoing curative resection for non-small cell lung cancer found to harbour mediastinal lymphadenopathy. A total of 77 papers were identified using the reported search, of which 11 represented the best evidence to answer the clinical question. Only studies reporting on survival data of patients receiving adjuvant chemotherapy with and without PORT were included in this analysis. The authors, date, journal, country, study type, population, outcomes and key results are tabulated. Six studies reported a statistically significant positive impact of PORT on long-term or disease-free survival (DFS) (P = 0.048–0.0001). Five more studies found no difference in terms of survival between patients receiving and not receiving PORT. Among the 11 studies, only two were randomized controlled, with one of them reporting improved disease-free (P = 0.041) but not overall survival (P = 0.073), while the other finding no difference in survival. Furthermore, three more studies reported on DFS and/or locoregional recurrence of the disease. One of these studies reported a significantly improved DFS among patients receiving PORT (P = 0.003), while two of them reported a reduced rate of locoregional recurrence in this group (P = 0.032–0.009). Many studies report a positive effect of PORT when combined in parallel or sequentially with adjuvant chemotherapy in terms of long-term, disease free survival or locoregional control of the disease in patients who have undergone surgical resection of NSCLC and are found to harbour N2 disease. However, these reports are counterbalanced by an almost equal number of studies which show no difference between PORT and no PORT. Only one study reported significantly increased radiation related adverse effects in patients undergoing chemotherapy and PORT.

  • Systematic review on the predictive ability of frailty assessment measures
           in cardiac surgery
    • Authors: Abdullahi YS; Athanasopoulos LV, Casula RP, et al.
      Abstract: AbstractOBJECTIVES: Patient frailty is increasingly recognised as contributing to adverse postoperative outcomes in cardiothoracic surgery. The goal of this review is to evaluate the predictive ability of frailty scoring systems and their limitations in risk assessment of patients undergoing cardiac surgery.METHODS: Frailty studies were identified by searching electronic databases. Studies in which the measuring instrument was defined as a multidimensional tool focusing on a population undergoing cardiac operations were included. The focus was on the predictive ability of frailty in this population and a comparison with conventional risk scoring systems. Unfortunately, the lack of a significant number of studies with the same postoperative outcome precluded a formal meta-analysis.RESULTS: Of 783 studies identified in our initial search, 6 fulfilled our inclusion criteria. Frailty was identified as a predictor of mortality, morbidity and/or prolonged hospital stay in patients undergoing cardiac surgery. Our systematic review revealed the increased application of frailty scores compared to standardized risk stratification scores in cardiothoracic patients. In approximately 50% of these studies, frailty scores continued to be predictive even after adjusting for the conventional risk scoring systems.CONCLUSIONS: The assessment of frailty may enhance the preoperative workup and offer an optimized risk stratification measure in patients undergoing cardiothoracic procedures even though the reporting standards of calibration and classification measures have been relatively poor.

  • Dialyzer-based cell salvage system: a superior alternative to conventional
           cell salvage in off-pump coronary artery bypass grafting
    • Authors: Malhotra A; Garg P, Bishnoi A, et al.
      Abstract: AbstractOBJECTIVES: Our goal was to test the hypothesis that the use of a dialyzer-based cell salvage system during off-pump coronary artery bypass grafting (OPCABG) reduces requirements for homologous blood transfusions (HBT) and improves postoperative haemtochemical parameters.METHODS: Data were prospectively collected for 222 patients who had OPCABG using 3 different cell salvage techniques: (1) dialyzer-based cell salvage (DBCS) (n = 75), (2) conventional cell salvage (CCS) (n = 73) and (3) without cell salvage (WCS) (n = 74). Salvaged blood was transfused at the end of the operation. The primary outcome of the study was the amount of homologous blood transfused. Secondary outcomes were changes in haemtochemical parameters, postoperative bleeding, need for non-invasive ventilation (NIV), postoperative complications, renal dysfunction, clotting derangement, duration of intensive care unit (ICU) and hospital stay and mortality rates.RESULTS: There were no deaths. In patients with >1000 ml blood loss, there was a significant reduction in HBT in the DBCS group (300 ± 161 ml) compared with the WCS group (550 ± 85 ml) (P

  • Mitral valve replacement using a handmade construct in an infant
    • Authors: Bibevski S; Levy A, Scholl FG.
      Abstract: AbstractWe recently reported the feasibility of a handmade left atrioventricular valve using decellularized extracellular matrix for 3 months in a failed repair of AV canal defect. We present the use of an extracellular matrix mitral valve for 9 months in an infant with an un-repairable congenitally malformed valve. The valve functioned perfectly without anticoagulation until the patient expired from non-cardiac complications of their fibrillin gene defect. This report adds further experience using valves made from extracellular matrix in the systemic ventricle both in terms of application and in terms of short-term durability of the construct.

  • Posterior uniportal video-assisted thoracoscopic surgery for resection of
           the apical segment of the right lower lobe followed by completion
    • Authors: Stamenovic D; Messerschmidt A.
      Abstract: AbstractUniportal thoracoscopic resections offer less pain and better cosmetic results. They are usually performed through an antero-lateral incision. Posterior uniportal approach has not been described yet. A 65-year-old female was admitted to our clinic for the treatment of an adenocarcinoma, located in the apical segment of the right lower lobe. Owing to the ideal location and size, anatomical segment resection and radical lymphadenectomy was planned. Fissureless video-assisted thoracoscopic resection of the apical segment of the right lower lobe, using a uniportal posterior approach was performed, followed by mediastinal lymphadenectomy. However, resection margins showed microscopic presence of lepidic tumour on frozen section analysis, so we needed to proceed with a completion lower lobectomy. Postoperative course was event-free and the patient was discharged on the 4th postoperative day. The 1.8-cm large tumour was diagnosed to be primary lepidic (80%) and acinar (20%) adenocarcinoma and the final TNM was pT2aN0M0.

  • A minimally invasive approach for open surgical thoracoabdominal aortic
           replacement: experimental concept for a novel surgical procedure
    • Authors: Andrási TB; Kékesi V, Merkely B, et al.
      Abstract: AbstractOBJECTIVES: We aimed to develop a simple, reliable, and timesaving technique for the therapy of thoracoabdominal aortic (TAA) aneurysms that are not suitable for endovascular repair.METHODS: In this pilot study, we sought to combine the advantages of classic open vascular procedure with the use of endoscopic surgical tools and small skin incisions to develop a minimally invasive approach for TAA replacement. The following procedures were used: endoscopic exposure and closure of the lower intercostal arteries; small posterolateral thoracotomy and left retroperitoneal incisions to expose the anastomotic regions of the aorta; partial anticoagulation; passive bypass and sequential aortic clamping; tunnelling of the graft through the native aortic lumen (endoaneurysmorrhaphy) and open performance of vascular anastomosis.RESULTS: Five mixed-breed dogs (25–35 kg) underwent minimally invasive TAA replacement. All animals survived the operation without blood transfusion (lowest Hb = 5.5 mg/dl). Total operation time was 364 ± 46.3 min. Clamping times were 17.6 ± 3.2 min for proximal anastomosis, 33.2 ± 2.48 min for visceral patch and 11 ± 2.3 min for distal anastomosis. The pull-through procedure of graft through the native aorta was performed during the visceral clamp time.CONCLUSIONS: Surgical replacement of the TAA through small transverse incisions of the thoracic and abdominal wall is feasible and allows open performance of all vascular anastomosis with no leakage at any anastomotic site. Further experimental studies and clinical implementation are needed to establish the safety and long-term outcome of minimally invasive TAA replacement as a possible primary therapeutic tool for complex aneurysms that are not suitable for endovascular treatment and require open surgical repair.

  • Predictors for quality of life of patients with a portable
           out-of-centre-implanted extracorporeal membrane oxygenation device
    • Authors: Rückert F; Steinke T, Flöther L, et al.
      Abstract: AbstractOBJECTIVES: Despite progress in the treatment of cardiopulmonary organ failure, the mortality rate for patients with acute respiratory distress syndrome (ARDS) and cardiogenic shock remains high. Extracorporeal membrane oxygenation (ECMO) is a promising treatment option, but long-term outcomes and health-related quality of life (HRQOL) are unknown.METHODS: Detailed information related to pre- and post-device data and outcomes from a consecutive sample of 71 patients treated with ECMO was analysed. Long-term survivors were given a detailed follow-up examination after a median time of 31 months that included multiple scoring systems for HRQOL assessment.RESULTS: Seventy-one patients received a portable out-of-centre-implanted ECMO system. The survival rate at hospital discharge was 48%. Median HRQOL scores were 80% on the Karnofsky index (normal ≥80%), 80% on the Euroqol-5D (normal ≥75%) and 73.1% on the quality-of-life index (normal ≥70%). Mental scores were 96.7% on the Mini-Mental State Examination (normal ≥90.0%), 77.8% on the DemTect (normal ≥72.0%), 87.0% on the test for early detection of dementia with depression demarcation (TFDD; normal ≥74.0%) and confirmed good mental state and HRQOL for patients at follow-up. Univariate analysis for in-hospital mortality indicated that ventilation time before device implantation, higher Acute Physiology and Chronic Health Evaluation (APACHE) II score, higher lactate level at the time of ECMO implantation and female gender were associated with adverse outcomes.CONCLUSIONS: In our cohort of patients, survivors of out-of-hospital ECMO implantation demonstrated good mental and quality-of-life conditions with well-recovered cardiopulmonary function during long-term follow-up. The indicators for adverse outcomes, pre-implantation lactate levels, pre-ventilation time and APACHE II score, should be considered before implantation of an ECMO device.CLINICAL TRIAL: This study is registered at DRKS (Deutsches Register Klinischer Studien) under the code DRKS00009735 and was submitted to the WHO.

  • Three-dimensional virtual bronchoscopy using a tablet computer to guide
           real-time transbronchial needle aspiration
    • Authors: Fiorelli A; Raucci A, Cascone R, et al.
      Abstract: AbstractOBJECTIVES: We proposed a new virtual bronchoscopy tool to improve the accuracy of traditional transbronchial needle aspiration for mediastinal staging.METHODS: Chest-computed tomographic images (1 mm thickness) were reconstructed with Osirix software to produce a virtual bronchoscopic simulation. The target adenopathy was identified by measuring its distance from the carina on multiplanar reconstruction images. The static images were uploaded in iMovie Software, which produced a virtual bronchoscopic movie from the images; the movie was then transferred to a tablet computer to provide real-time guidance during a biopsy. To test the validity of our tool, we divided all consecutive patients undergoing transbronchial needle aspiration retrospectively in two groups based on whether the biopsy was guided by virtual bronchoscopy (virtual bronchoscopy group) or not (traditional group). The intergroup diagnostic yields were statistically compared.RESULTS: Our analysis included 53 patients in the traditional and 53 in the virtual bronchoscopy group. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy for the traditional group were 66.6%, 100%, 100%, 10.53% and 67.92%, respectively, and for the virtual bronchoscopy group were 84.31%, 100%, 100%, 20% and 84.91%, respectively. The sensitivity (P = 0.011) and diagnostic accuracy (P = 0.011) of sampling the paratracheal station were better for the virtual bronchoscopy group than for the traditional group; no significant differences were found for the subcarinal lymph node.CONCLUSIONS: Our tool is simple, economic and available in all centres. It guided in real time the needle insertion, thereby improving the accuracy of traditional transbronchial needle aspiration, especially when target lesions are located in a difficult site like the paratracheal station.

  • Extrathymic malignancies associated with thymoma: a forty-year experience
           at a single institution
    • Authors: Kamata T; Yoshida S, Wada H, et al.
      Abstract: AbstractOBJECTIVES: Patients with thymoma are reported to have an increased risk for developing second malignancies. The aim of this study was to assess the incidence of second malignancies among patients with thymoma. We focused especially on the impact that lung cancer has on survival in these patients.METHODS: Three hundred and thirty-five patients who underwent surgery for thymoma in Chiba University Hospital from January 1971 to November 2012 were included in this study. Patient records were reviewed retrospectively for data on background, treatment, second malignancies and clinical outcome.RESULTS: Fourteen patients had a history of malignancy until the time of operation, with an additional 20 diagnosed simultaneously with the thymoma. Forty-three malignant lesions in 33 patients were found post-thymectomy. Lung cancer was diagnosed in 17 patients, far exceeding the expected number in the cohort, which was calculated according to Japanese national data. The median survival time of the thymoma patients who had lung cancer at the time of surgery was 5.8 years. The survival of patients with thymoma and lung cancer was poor in comparison with that of others.CONCLUSIONS: Secondary lung cancer is frequently found in thymoma patients and could be one of the factors limiting survival. We recommend an annual computed tomographic scan of the thorax to detect not only recurrent thymoma but also lung cancer at an early stage in order to improve the survival of these patients.

  • Minimally invasive endoscopic surgery versus catheter-based device
           occlusion for atrial septal defects in adults: reconsideration of the
           standard of care
    • Authors: Schneeberger Y; Schaefer A, Conradi L, et al.
      Abstract: AbstractOBJECTIVES: Percutaneous ostium secundum atrial septal defect (ASD II) closure has become the standard of care for treatment of congenital ASD II in adults. Nevertheless, patients are frequently ineligible for this technique due to challenging morphology. In such cases, closure via minimally invasive cardiac surgery (MICS) is an appropriate treatment option. The aim of this study is to compare outcomes of MICS and use of a percutaneous Amplatzer septal occluder (ASO) device for treatment of ASD II in adults.METHODS: From July 2002 to June 2014, 95 patients underwent MICS for congenital ASD II closure. During the same period, 169 patients underwent ASO procedure. Outcomes in terms of remaining ASD II, new onset atrial fibrillation (AF), post-interventional stroke, myocardial infarction and the post procedural implementation of anticoagulation were compared.RESULTS: Apart from age (38.3 ± 12.7 vs 49.6 ± 15.7 years, P
