- OBJECTIVES: Patients with chronic obstructive pulmonary disease (COPD) who also have acute coronary syndromes are a high-risk population with a high mortality rate. Little is known about these patients following coronary artery bypass grafting (CABG). METHODS: Patients presenting with acute coronary syndromes between 2006 and 2014 with an angiogram showing 3-vessel disease or left main coronary artery involvement who were treated with CABG or percutaneous coronary intervention (PCI) only were included from the nationwide SWEDEHEART registry. Patients were stratified according to COPD status and compared with regard to outcome. The primary end-point was the 5-year mortality rate; secondary outcomes were the 30-day mortality rate and in-hospital complications after CABG. RESULTS: We identified 6985 patients in the population who had CABG (COPD prevalence = 8.0%) and 14 209 who had PCI only (COPD = 8.2%). Patients with COPD were older and had more comorbidities than patients without COPD. The 5-year mortality rate was nearly doubled in patients with COPD versus patients without COPD (CABG: 27.2% vs 14.5%, P < 0.001; PCI only: 50.1% vs 29.1%, P < 0.001). After adjusting for age, sex and comorbidities, patients with COPD in both CABG-treated [hazard ratio = 1.52 (1.25-1.86), P < 0.001] and PCI-treated populations still had a significantly higher 5-year mortality rate. COPD was also independently associated with significantly more postoperative infections in need of antibiotics [odds ratio = 1.48 (1.07-2.04), P = 0.017] and pneumonia [odds ratio = 2.21 (1.39-3.52), P = 0.001]. CONCLUSIONS: Patients with COPD presenting with acute coronary syndromes and severe coronary artery disease are a high-risk population following CABG or PCI only, with higher risk of long-term and short-term death and postoperative infections. Preventive measures, including careful monitoring for signs of infection and prompt antibiotic treatment when indicated, should be considered.

- OBJECTIVES: Stroke is a serious complication in patients with acute type A aortic dissection (ATAAD). Previous studies investigating stroke in ATAAD patients have been limited by small cohorts and have shown diverging results. We sought to identify risk factors for stroke and to evaluate the effect of stroke on outcomes in surgical ATAAD patients. METHODS: The Nordic Consortium for Acute Type A Aortic Dissection database included patients operated for ATAAD at 8 Scandinavian Hospitals between 2005 and 2014. RESULTS: Stroke occurred in 177 (15.7%) out of 1128 patients. Patients with stroke presented more frequently with cerebral malperfusion (20.6% vs 6.3%, P < 0.001), syncope (30.6% vs 17.6%, P < 0.001), cardiogenic shock (33.1% vs 20.7%, P < 0.001) and pericardial tamponade (25.9% vs 14.7%, P < 0.001) and more often underwent total aortic arch replacement (10.7% vs 4.7%, P = 0.016), compared to patients without stroke. In the 86 patients presenting with cerebral malperfusion, 38.4% developed stroke. Thirty-day and 5-year mortality in patients with and without stroke were 27.1% vs 13.6% and 42.9% vs 25.6%, respectively. Stroke was an independent predictor of early- [odds ratio 2.02, 95% confidence interval (CI) 1.34-3.05; P < 0.001] and midterm mortality (hazard ratio 1.68, 95% CI 1.27-2.23; P < 0.001). CONCLUSIONS: Stroke in ATAAD patients is associated with increased early- and midterm mortality. Preoperative cerebral malperfusion and impaired haemodynamics, as well as total aortic arch replacement, were more frequent among patients who developed stroke. Importantly, a large proportion of patients presenting with cerebral malperfusion did not develop a permanent stroke, indicating that signs of cerebral malperfusion should not be considered a contraindication for surgery.

- Acute aortic dissection type A is a life-threatening condition, warranting immediate surgery. Presentation with sudden chest pain confers a risk of misdiagnosis as acute coronary syndrome resulting in subsequent potent antiplatelet treatment. We investigated the impact of dual antiplatelet therapy (DAPT) on bleeding and mortality using the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) database.The NORCAAD database is a retrospective multicentre database where 119 of 1141 patients (10.4%) had DAPT with ASA+clopidogrel (n=108) or ASA+ticagrelor (n=11) before surgery. The incidence of major bleeding and 30-day mortality was compared between DAPT and non-DAPT patients with logistic regression models before and after propensity score matching.Before matching, 51.3% of DAPT patients had major bleeding when compared to 37.7% of non-DAPT patients (P=0.0049). DAPT patients received more transfusions of red blood cells [median 8U (Q1-Q3 4-15) vs 5.5U (2-11), P<0.0001] and platelets [4U (2-8) vs 2U (1-4), P=0.0001]. Crude 30-day mortality was 19.3% vs 17.0% (P=0.60). After matching, major bleeding remained significantly more common in DAPT patients, 51.3% vs 39.3% [odds ratio (OR) 1.63, 95% confidence interval (CI) 1.05-2.51; P=0.028], but mortality did not significantly differ (OR 0.88, 95% CI 0.51-1.50; P=0.63). Major bleeding was associated with increased 30-day mortality (adjusted OR 2.44, 95% CI 1.72-3.46; P<0.0001).DAPT prior to acute aortic dissection repair was associated with increased bleeding and transfusions but not with mortality. Major bleeding per se was associated with a significantly increased mortality. Correct diagnosis is important to avoid DAPT and thereby reduce bleeding risk, but ongoing DAPT should not delay surgery.

- To update the European System for Cardiac Operative Risk Evaluation (EuroSCORE) risk model. A dedicated website collected prospective risk and outcome data on 22 381 consecutive patients undergoing major cardiac surgery in 154 hospitals in 43 countries over a 12-week period (May-July 2010). Completeness and accuracy were validated during data collection using mandatory field entry, error and range checks and after data collection using summary feedback confirmation by responsible officers and multiple logic checks. Information was obtained on existing EuroSCORE risk factors and additional factors proven to influence risk from research conducted since the original model. The primary outcome was mortality at the base hospital. Secondary outcomes were mortality at 30 and 90 days. The data set was divided into a developmental subset for logistic regression modelling and a validation subset for model testing. A logistic risk model (EuroSCORE II) was then constructed and tested. Compared with the original 1995 EuroSCORE database (in brackets), the mean age was up at 64.7 (62.5) with 31% females (28%). More patients had New York Heart Association class IV, extracardiac arteriopathy, renal and pulmonary dysfunction. Overall mortality was 3.9% (4.6%). When applied to the current data, the old risk models overpredicted mortality (actual: 3.9%; additive predicted: 5.8%; logistic predicted: 7.57%). EuroSCORE II was well calibrated on testing in the validation data subset of 5553 patients (actual mortality: 4.18%; predicted: 3.95%). Very good discrimination was maintained with an area under the receiver operating characteristic curve of 0.8095. Cardiac surgical mortality has significantly reduced in the last 15 years despite older and sicker patients. EuroSCORE II is better calibrated than the original model yet preserves powerful discrimination. It is proposed for the future assessment of cardiac surgical risk.

- Objective: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) is used to identify patients at high risk for aortic valve replacement (AVR) in whom alternative procedures, such as trans-catheter aortic valve implantation (TAVI), may be appropriate. The aim of the present study was to calibrate and validate the EuroSCORE for different cardiac surgery procedures to improve patient selection for valve surgery. Methods: The study included 46516 patients undergoing open cardiac surgery during 2001-2007. A fivefold cross-validation technique was used to calibrate four different models. Model discrimination was determined by the area under the receiver operating characteristic (ROC) curve and model calibration by the Hosmer-Lemeshow (H-L) test. Results: The actual and predicted 30-day mortality was 3.2%. The discrimination (ROC area) of the calibrated 30-day mortality prediction models was 0.79 for coronary bypass surgery, 0.77 for mitral valve surgery (MVS), and 0.75 for miscellaneous procedures, compared with 0.78 (p=0.199), 0.74 (p=0.077), and 0.72 (p=0.001), respectively, for the original EuroSCORE. The discrimination for AVR was the same for the calibrated and the original EuroSCORE model (0.70). The H-L test gave a p-value of 0.104 for the calibrated and <0.001 for the original EuroSCORE model. Conclusions: A calibration of EuroSCORE resulted in an acceptable predictive capacity for 30-day mortality, and improved discrimination and calibration for MVS and miscellaneous procedures. However, the poor discriminatory for the AVR procedure suggests that the EuroSCORE may not be satisfying for assessing risk prior to TAVI and that more optimized risk stratification models may be needed.

- OBJECTIVES: To report long-term survival and predictors of mortality in patients included in a large, contemporary, multicentre, multinational database: Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD), which consists of 8 centres in 4 Nordic countries.METHODS: Currently, NORCAAD includes 1159 patients operated between 2005 and 2014. In 30-day survivors (n = 955, 82%), the Kaplan-Meier and Cox proportional hazard methods were used to analyse medium-term (up to 8 years) survival and relative survival versus a matched normal population. Pre- and intraoperative predictors were expressed as hazard ratio (HR) with 95% confidence interval (95% CI).RESULTS: Cumulative follow-up was 3514 patient-years with a median of 3.2 years (range 0-10.2 years). Survival was 95% (95% CI 93-96) at 1 year, 86% (95% CI 83-88) at 5 years and 76% (95% CI 72-81) at 8 years. Relative survival versus a matched normal population was 95% (95% CI 94-97) at 1 year, 90% (95% CI 87-93) at 5 years and 85% (95% CI 80-90) at 8 years. In multivariable analysis, increased age (HR 1.05 per year, 95% CI 1.04-1.07), previous abdominal or thoracic aortic repair (HR 3.2, 95% CI 1.6-6.4) and chronic renal disease (HR 2.7, 95% CI 1.2-6.2) were associated with increased medium-term mortality. Open distal anastomosis (HR 0.55, 95% CI 0.35-0.87) and operation in the 2010-2014 period (HR 0.90, 95% CI 0.83-0.97) were associated with decreased medium-term mortality.CONCLUSIONS: Medium-term survival after acute Type A aortic dissection in the NORCAAD registry is satisfactory, close to a matched normal population and improved in the later part of the study period. The use of open distal anastomosis was associated with decreased medium-term mortality.

- Objective: Negative pressure wound therapy (NPWT) is a recently introduced treatment modality for post-sternotomy mediastinitis. The aim of this study was to compare the mortality rate, the sternal re-infection rate and the length of hospital stay in patients with post-sternotomy mediastinitis after NPWT and conventional treatment. Methods: We retrospectively analysed 118 patients with post-sternotomy mediastinitis after cardiac surgery. One group of 69 patients was treated with NPWT and the other group of 49 patients with conventional therapy. Results: There were no major differences between the two groups concerning preoperative data (EuroScore) or primary cardiac surgery (mainly coronary artery bypass grafting). NPWT therapy was found to reduce mortality rate (P = 0.005) and sternal re-infection rate (P = 0.008) compared with conventional treatment and tended to lead to a shorter length of hospital stay (P = 0.08). Conclusions: NPWT for post-sternotomy mediastinitis demonstrates encouraging clinical results with a reduction of the mortality rate and the sternal re-infection rate compared with conventional treatment. The results support NPWT as the first-line treatment for deep sternal wound infections. (C) 2010 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V. All rights reserved.

- The implementation of new surgical techniques offers chances but carries risks. Usually, several years pass before a critical appraisal and a balanced opinion of a new treatment method are available and rely on the evidence from the literature and expert's opinion. The frozen elephant trunk (FET) technique has been increasingly used to treat complex pathologies of the aortic arch and the descending aorta, but there still is an ongoing discussion within the surgical community about the optimal indications. This paper represents a common effort of the Vascular Domain of EACTS together with several surgeons with particular expertise in aortic surgery, and summarizes the current knowledge and the state of the art about the FET technique. The majority of the information about the FET technique has been extracted from 97 focused publications already available in the PubMed database (cohort studies, case reports, reviews, small series, meta-analyses and best evidence topics) published in English.

- Objective: The novel axial flow left ventricular assist device HeartMate II was introduced into clinical practice in Europe as part of the pilot study and after CE approval in November 2005. In order to get an overview of the use and performance of the device in Europe a group of investigators was founded to compare the initial results. Methods: In a retrospective analysis of the first 101 consecutive cases in Europe, data were collected with regard to postoperative outcome and severe adverse events and anticoagulation protocols. Results were stratified by intention to treat as a bridge to transplant or as chronic support therapy in heart failure (destination therapy). Results: In 70% of patients, the HeartMate II was intended as a bridge to transplant therapy, in 30%, it was used as a destination therapy device. The perioperative mortality post implant was 20% in the bridge to transplant patients and 7% in the destination therapy arm. However, after 1 year a comparable survival was observed in both groups (69% destination therapy, 63% bridge to transplant). Main causes of death were multiple organ failure (n = 12) and cerebrovascular accidents (n = 5). All, but one cerebrovascular accident occurred in the first 9 days after surgery. Only one other death was reported thereafter and there was no mechanical failure of the device. Conclusions: Even in the early experience the HeartMate II was used as a chronic support device in a substantial number of patients in Europe. Although the total experience is still limited, the incidence of cerebrovascular accidents is very low and the survival beyond the perioperative period is excellent. © 2008 European Association for Cardio-Thoracic Surgery.
