OBJECTIVES The goal was to develop a scoring system to predict the 30-day mortality rate for patients undergoing surgery for acute type A aortic dissection on the basis of the German Registry for Acute Type A Aortic Dissection (GERAADA) data set and to provide a Web-based application for standard use. METHODS A total of 2537 patients enrolled in GERAADA who underwent surgery between 2006 and 2015 were analysed. Variable selection was performed using the R-package FAMoS. The robustness of the results was confirmed via the bootstrap procedure. The coefficients of the final model were used to calculate the risk score in a Web-based application. RESULTS Age [odds ratio (OR) 1.018, 95% confidence interval (CI) 1.009–1.026; P < 0.001; 5-year OR: 1.093], need for catecholamines at referral (OR 1.732, 95% CI 1.340–2.232; P < 0.001), preoperative resuscitation (OR 3.051, 95% CI 2.099–4.441; P < 0.001), need for intubation before surgery (OR 1.949, 95% CI 1.465–2.585; P < 0.001), preoperative hemiparesis (OR 1.442, 95% CI 0.996–2.065; P = 0.049), coronary malperfusion (OR 1.870, 95% CI 1.386–2.509; P < 0.001), visceral malperfusion (OR 1.748, 95% CI 1.198–2.530; P = 0.003), dissection extension to the descending aorta (OR 1.443, 95% CI 1.120–1.864; P = 0.005) and previous cardiac surgery (OR 1.772, 95% CI 1.048–2.903; P = 0.027) were independent predictors of the 30-day mortality rate. The Web application based on the final model can be found at https://www.dgthg.de/de/GERAADA_Score. CONCLUSIONS The GERAADA score is a simple, effective tool to predict the 30-day mortality rate for patients undergoing surgery for acute type A aortic dissection. We recommend the widespread use of this Web-based application for standard use.

BackgroundThe purpose of this prospective study was to evaluate the effects and functional outcome of central extracorporeal life support (ECLS) with left ventricular decompression for the treatment of refractory cardiogenic shock and lung failure.MethodsBetween August 2010 and August 2013, 12 consecutive patients (2 female) with a mean age of 31.6 ± 15.1 years received central ECLS with left ventricular decompression for the treatment of refractory cardiogenic shock and lung failure. Underlying disease was acute cardiac decompensation due to dilated cardiomyopathy (n = 3, 25%), coronary artery disease with acute myocardial infarction (AMI) (n = 3, 25%), and acute myocarditis (n = 6, 50%). We routinely implemented ECLS by cannulating the ascending aorta, right atrium and inserting a left ventricular decompression cannula vent via the right superior pulmonary vein.ResultsAll patients were successfully bridged to either recovery (n = 3, 25%), long-term biventricular support (n = 6, 50%) or cardiac transplantation (n = 3, 25%). Seven patients (58.3%) were discharged after a mean hospital stay of 42 ± 11.9 days. The overall survival from ECLS implantation to the end of the study was 58.3%. The cumulative ICU stay was 23.1 ± 9.6 days. The length of support was 8.0 ± 4.3 days (range 3-17 days).ConclusionsWe strongly recommend left ventricular decompression in refractory cardiogenic shock and lung failure to avoid pulmonary edema, left heart distension and facilitate myocardial recovery.

Aims The occurrence of hyperbilirubinaemia after heart surgery using cardiopulmonary bypass or post‐operative heart failure is fairly common. We investigated the incidence, predictive value, and post‐operative outcome of hyperbilirubinaemia after cardiac surgery in an effort to identify potential risk factors and significance on clinical outcome. Methods and results Between 2006 and 2016, 1272 (10.1%) out of 12 556 patients developed hyperbilirubinaemia, defined as bilirubin concentration >3 mg/dL, during post‐operative course at our institution. All patients who were operated using cardiopulmonary bypass were included. Hepatic dysfunction was diagnosed preoperatively in 200 patients (15.7%), whereas mean model of end‐stage liver disease score was 11.22 ± 4.99. Early mortality was 17.4% with age [hazard ratio (HR) 1.019, 95% confidence interval (CI) 1.008–1.029; P = 0.001], diabetes (HR 1.115, CI 1.020–1.220; P = 0.017), and emergent procedures (HR 1.315, CI 1.012–1.710) as multivariate predictors. Post‐operative predictors were low‐output syndrome (HR 3.193, 95% CI 2.495–4.086; P < 0.001), blood transfusion (HR 1.0, CI 1.0–1.0; P < 0.001), and time to peak bilirubin (HR 1.1, CI 1.0–1.1; P < 0.001). We found an increased correlation with mortality at 3.5 post‐operative day as well as an optimal cut‐off value for bilirubin of 5.35 mg/dL. A maximum bilirubin of 25.5 mg/dL was associated with 99% mortality. Survival analysis showed significantly decreased survival for patients who developed late, rather than early, hyperbilirubinaemia. Conclusions Post‐operative hyperbilirubinaemia is a prevalent threat after cardiopulmonary bypass, associated with high early mortality. The timing and amount of peak bilirubin concentration are linked to the underlying pathology and are predictors of post‐operative outcome. Patients with late development of steep hyperbilirubinaemia warrant meticulous post‐operative care optimizing cardiac and end organ functions before reaching the point of no return.
