    ABSTRACT: Objectives: EuroSCORE II has been implemented with the view to providing better performance than the previous logistic EuroSCORE. However, until now, no external validations have been carried out in the minimally invasive context. Therefore, we sought to validate the accuracy of EuroSCORE II in a retrospective series of consecutive patients undergoing minimally invasive mitral valve surgery. Methods: Data of 1609 consecutive patients who underwent minimally invasive mitral valve surgery in our institution were retrospectively reviewed. The accuracy of EuroSCORE II was assessed in terms of discrimination and calibration. Discrimination was tested via analysis of the area under the curve of receiver operator characteristic; calibration was achieved by calculating the observed versus expected mortality ratio and the Hosmer-Lemeshow test for test probability; global accuracy was assessed by using Brier's score; results were compared with the previous logistic EuroSCORE version. EuroSCORE II performance was also tested for discrimination of postoperative complications. Discrimination subgroup analysis was carried out for single surgeon results, and for high-risk patients those outliers were defined after boxplot analysis (EuroSCORE II ≥6%). Results: EuroSCORE II showed good discrimination power (area under the curve 0.846), and was statistically superior to logistic EuroSCORE (P = 0.01). In terms of calibration, both EuroSCORE II and logistic over-predicted mortality; with regard to adverse events, the discrimination of EuroSCORE II was adequate for acute renal failure, low-output syndrome and increased intensive care unit stay; area under the curve of receiver operating characteristic for high-risk patients with EuroSCORE ≥6% was suboptimal (0.654); single surgeon results did not influence the discrimination of EuroSCORE II. Conclusions: EuroSCORE II showed good discrimination power in our series of minimally invasive mitral valve patients; however, it over-predicted mortality. Individual performance did not influence discrimination. Performance was suboptimal for prediction of complications and for high-risk subgroup in-hospital mortality.

    ABSTRACT: A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether salvage pulmonary resection is possible and worthwhile for patients with recurrence of non-small-cell lung cancer (NSCLC) after prior definitive non-operative therapy. A total of nine reports were identified using the reported search, of which four represented the best available evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. All studies were retrospective. In total, 48 pulmonary salvage resections were performed in 47 patients after prior definitive radiation, chemoradiation or stereotactic body radiation therapy, of which 28 were lobectomies (including 1 sleeve lobectomy), 12 pneumonectomies, 4 bilobectomies and 4 sublobar resections (2 segmentectomies and 2 wedge resections). Postoperative complications ranged from 0 to 58% (mean from four studies 42.5%). Only one study reported any mortality (4%), the other three had zero mortality. Median postoperative survival was reported in two studies and ranged from 9 to 30 months. Experience with salvage lung resection for locally recurrent NSCLC, after prior definitive non-surgical treatment, remains limited. Therefore, this analysis was based on only 48 resections in 47 patients from four retrospective studies. Nevertheless, the published data suggest that salvage lung surgery for recurrent, previously non-operatively managed non-small-cell lung cancer is a worthwhile treatment option with good survival, acceptable morbidity and low mortality. © The Author 2015.

    ABSTRACT: Objectives: To assess the postoperative incidence of major complications in high-risk patients following video-assisted thoracoscopic surgery (VATS) lobectomy for lung cancer compared with their lower risk counterparts. Methods: A retrospective analysis on prospectively collected data of 348 consecutive patients subjected to VATS lobectomy (August 2012-September 2014) was performed. Patients were defined as high risk if one or more of the following characteristics were present: age >75 years, forced expiratory volume in 1 s (FEV1) <50%, carbon monoxide lung diffusion capacity (DLCO) <50%, history of coronary artery disease (CAD). Severity of complications was graded using the Thoracic Morbidity and Mortality (TM&M) score; major complications were defined if the TM&M score was greater than 2. The propensity score was used to match high-risk patients with their lower risk counterparts in order to minimize the influence of other confounders on outcome. The following variables were used to construct the propensity score: gender, side of operation, body mass index, American Society of Anaesthesiologists score, Eastern Cooperative Oncology Group score, Charlson's Comorbidity Index, number of functioning segments resected. Results: The high-risk group consisted of 141 patients (age >75 years: 84 patients; FEV1 <50: 14 patients; DLCO <50: 25 patients; history of CAD: 37 patients). The propensity score yielded two groups of 135 patients (high-risk vs low-risk) well matched for several baseline characteristics except for a lower performance status in the higher-risk group. Compared with their low-risk counterparts, high-risk patients had a higher incidence of cardiopulmonary complications (28 cases, 21% vs 14 cases, 10%; P < 0.0001) and major cardiopulmonary complications (12 cases, 9% vs 3 cases, 2%; P < 0.0001). Postoperative stay was 3 days longer in high-risk patients (8.6 vs 5.5 days, P = 0.0031). The 30-day or in-hospital mortality rates were not different between the two groups (2 cases, 1.5% vs 3 cases, 2.2%, P = 0.93). Conclusions: The incidence of major complications after VATS lobectomy in high-risk patients is low, but not negligible. This information can be used when discussing surgical risk with the patient during preoperative counselling.

    ABSTRACT: OBJECTIVES: Chronic kidney disease (CKD) is prevalent in patients undergoing aortic valve replacement (AVR). We sought to evaluate the impact of AVR on estimated glomerular filtration rate (eGFR) levels and determine the impact of reversibility of CKD on postoperative outcomes. METHODS: We retrospectively reviewed 2169 patients who underwent isolated AVR between 2000 and 2012. eGFR was calculated using the CKD-EPI formula. Based on preoperative eGFR, patients were divided into three groups: NoCKD (eGFR >60, n = 1417), ModCKD (eGFR = 30–60, n = 619) and SevCKD (eGFR = 15–30, n = 86). End-stage renal disease patients (eGFR <15 and/or dialysis, n = 47) were excluded from the study. RESULTS: Before AVR, eGFR in the NoCKD, ModCKD and SevCKD groups was 81.3 ± 14.2, 48.9 ± 8.10 and 25.3 ± 4.12 ml/min/1.73 m2, respectively. NoCKD patients showed a decline in eGFR during the first month postoperatively; thereafter, eGFR remained stable over 1 year. ModCKD and SevCKD patients demonstrated an initial improvement in eGFR, which peaked at 1 week postoperatively. In ModCKD, eGFR stabilized at a slightly lower level thereafter out to 1-year follow-up. In SevCKD, eGFR declined slightly out to 6 months postoperatively. Regardlessly, eGFR in ModCKD at 1 year and in SevCKD at 6 months postoperatively demonstrated sustained improvement over baseline eGFR. Reversibility of CKD was associated with a better long-term survival in the ModCKD group (P < 0.001) and short-term survival in the SevCKD group (P = 0.018). CONCLUSIONS: AVR confers a marked initial improvement in eGFR, which is sustained in patients with ModCKD and SevCKD, and is asso- ciated with a better survival. The reversible nature of CKD in certain patients warrants careful consideration during preoperative risk scoring and stratification.

    ABSTRACT: OBJECTIVES: The mitral valve (MV) is a complex three-dimensional (3D) intracardiac structure. 3D transthoracic and transoesophageal echocardiography are used to evaluate and describe the changes in the mitral valve apparatus due to degenerative or functional mitral regurgitation. These techniques are, however, not accurate enough to capture the dynamic changes during the cardiac cycle. We describe a novel multistage modelling (MSM) technique, using three-dimensional transoesophageal echocardiography (3D TOE), to visualize and quantify the MV during all the phases of the cardiac cycle. METHODS: Using 3D TOE, sets of images were obtained from 32 individuals who were undergoing surgery for other reasons and who did not have MV disease. These images were divided into six steps whereby every step represented one cardiac cycle. The image sets were then cropped and sliced at the level of MV, then imported and segmented by the open source software (3D Slicer) to create 3D mathematical models. The models were synchronized with patient's ECGs and then reunited and exported as multiphase dynamic models. The models were analysed in two steps: (i) direct step-by-step visual inspections of the MV from various angles and (ii) direct measurements of anteroposterior, intercommissural, anterolateral-posteromedial diameters, anterolateral angles and anteroposterior angles in systole and diastole at different levels. RESULTS: The segmentation results in 32 × 6 high-quality cropped MV. The division of models into six steps allows quantification and tracking of MV movement. Reunion of the models leads to creation of a full real-time simulation of the MV during the cardiac cycle. Synchronization of the models with ECG enables accurate simulation. Measurements of the diameters showed: median intercommissural diameters were increased with 10% from mid-systole to mid-diastole [31.9 mm (28.9-34.9), 34.8 mm (31.2-38.2), respectively, P-value <0.001]. This was also observed for anteroposterior diameters [33.8 mm (29.8-35.2), 37.1 mm (31.8-38.5), respectively, P-value <0.001]. Anterolateral-posteromedial diameter did not change significantly in both phases [43.7 mm (36.3-48.9), 43.5 mm (35.5-47.5), respectively]. Intercommissural and anteroposterior diameters were approximately the same in systole [31.9 mm (28.9-34.9) and 32.5 mm (29.8-35.2)] and diastole [34.8 mm (31.2-38.2) and 35.2 mm (31.8-38.5)]. Measurements of anteroposterior angle at the anterolateral junction showed that this angle was accentuated acutely in diastole rather in systole [115° (104-129), 126° (113-137), respectively, P-value <0.001]. It was the same when measuring the anterolateral angle [105° (97-113), 119° (106-130), respectively, P-value <0.001]. CONCLUSION: The novel MSM technique allows precise quantification of shape changes in MV, which may help in better understanding the normal MV physiology, facilitate the diagnosis of MV pathologies and lead to numerical simulation of MV flow and displacement. It can also help cardiac surgeons and cardiologists gain a better understanding of the MV and assist them in obtaining a reliable orientation in order to choose optimal treatment strategies and plan surgical interventions. The measurement of the new anterolateral angle allowed better quantification of mitral annulus angulation and could be considered as new parameter that may help in future development of a new generation of mitral rings.

    ABSTRACT: OBJECTIVES Literature reporting on large patient groups with the long-term follow-up is limited due to the low incidence of myxomas. This single-centre, retrospective study reports on the long-term follow-up (e.g. complications, recurrence and survival) of a substantial patient group operated for cardiac myxomas. METHODS Patients were retrospectively selected from a prospectively obtained database comprising patients who had undergone cardiac surgery in the Catharina Hospital from 1990 onwards. Baseline characteristics and perioperative data were obtained from the database. In case of insufficient information, medical reports were analysed. The echocardiogram and clinical follow-up data were collected at outpatient clinics. RESULTS Eighty-two patients were included, of which 48 were females with a mean age of 61.3 years (±13.8). The main presenting symptom was dyspnoea (29.3%), followed by chest pain (24.4%), palpitations (19.5%) and embolism (15.9%). Atrial fibrillation was the most frequent complication; directly postoperative (22%) and at the long-term follow-up (26.3%). The follow-up was completed in 95.1%, with a mean echocardiographic follow-up time of 72 months and with a longest follow-up of almost 23 years. There were no myxoma recurrences. Thirteen patients (16.5%) deceased during the follow-up, with a mean time of 9 years after surgery. CONCLUSIONS Myxomas carry the risk of severe complications. Surgical excision is the only option of treatment and gives excellent early and long-term results. Recurrence rates are low in case of non-hereditary myxomas, even in case of irradical excision. The echocardiographic follow-up therefore could be called into question. Link to full text:

    ABSTRACT: Positive pleural lavage cytology (PLC) is considered as a precursor condition of pleural dissemination (PD) or malignant pleural effusion (PE), and one of the poor prognostic factors in surgically resected non-small-cell lung cancer (NSCLC) patients. Although PD and PE are classified as M1a, PLC does not contribute to the tumour, node and metastasis (TNM) classification of the Union Internationale Contre le Cancer. This study aimed to evaluate the prognostic effect of positive PLC status in surgically resected NSCLC patients compared with PD and/or PE. We also aimed to consider the contribution of positive PLC status to the TNM classification. We reviewed 1572 consecutive patients with completely resected NSCLC, and analysed the relationship between PLC status, other clinicopathological factors and prognosis. The survival rates of 45 patients with PD and/or PE were also investigated. Positive preresection PLC (pre-PLC) status was observed in 56 patients. Pre-PLC status was significantly associated with other clinicopathological factors. Positive pre-PLC patients exhibited a worse 5-year overall survival (50.6%) compared with negative pre-PLC patients (78.0%), but better survival than PD and/or PE patients (21.0%). Prognosis of positive pre-PLC patients was equal to that of pT3, negative pre-PLC patients; survival equality was observed when patients were stratified according to pN0, pN1 and pN2. Positive pre-PLC had the significant prognostic effect in surgically resected NSCLC patients. However, it is not a contraindication for surgical resection, unlike PD and/or PE. Our data suggest that positive pre-PLC should be classified as pT3 in next TNM classification. © The Author 2015.
