Concomitant Coronary Artery Bypass in Patients with Acute Type A Aortic Dissection
Coronary Artery Bypass Grafting (CABG) is sometimes necessary in acute Type A Aortic Dissection (AAAD) repair. The aim of this study is to analyze the incidence, indications and influence in-hospital outcomes of AAAD repair requiring concomitant CABG in a high-volume single-center experience. Retrospective study of all consecutive AAAD patients. Those who underwent concomitant CABG were identified. Preoperative, intraoperative, postoperative and follow-up data were collected and analyzed. Between January 1, 2010 and December 31, 2016, 382 patients underwent emergency surgery for AAAD. Forty-one (10.7%) underwent concomitant CABG. In this group, mean age was 64 ± 14 years, 32 were male (78%). Indication for CABG was coronary dissection in 28 patients (68.3%), post-cardiopulmonary bypass (CPB) right heart failure in 7 (17.1%), post CPB left heart failure in (7.3%) and native coronary pathology in 3 (7.3%). In 33 (80.5%) one graft was needed, in 7 (17%) two were performed and in 1 patient (2.4%) 3 were necessary. The right coronary artery (RCA) was the only revascularized vessel in 26 cases (63.4%), the left coronary artery (LCA) alone in 11 (26.8%), and both coronary systems in 4 (9.8%). In-hospital mortality was 51.2% (N = 21); eight (19.5%) patients had postoperative myocardial infarction (MI) and 11 (26.8%) had a major neurological event. Multivariable logistic regression identified concomitant CABG as a predictor of in-hospital mortality (Odds Ratio (OR) = 3.8115, 95% CI= 0.514-2.138, p = 0.001). In our study, concomitant CABG was performed in 10.7% of AAAD repair surgery and it was associated with high in-hospital mortality.

Increasing atmospheric temperature implicates increasing risk for acute type A dissection in hypertensive patients
Background: Acute type A aortic dissection (AAAD) is a life-threatening condition with high mortality within 24 hours. We hypothesized if there is a correlation between seasonal weather changes and the occurrence of AAAD. The aim of the present study was to identify seasonal specific weather and patient characteristics predicting the occurrence of AAAD.
Methods: This is a retrospective analysis of all consecutive patients of our department with AAAD between January 1st 2006 and December 31st 2016. The national meteorological department provided the data of temperature, humidity and air pressure during the study period. The occurrence of AAAD, preoperative neurological impairment and mortality were analyzed in correlation with the obtained daily weather data within the entire cohort and in patients with and without hypertension separately.
Results: A total of 517 patients were included. Mean age was 63.4±13 years, 69.4% were male and 68.8% had documented hypertension. In-hospital mortality was 17.7%. In the whole cohort, the occurrence of AAAD was significantly increased in March, October, December (P=0.016). In hypertensive patients, the occurrence was increased 34% with rising temperature (0.1-9.6 °C, OR1.34, 95% CI: 1.06-1.69, P=0.015). There was no correlation between weather variables and preoperative neurological impairment or mortality.
Conclusions: Our data suggests a relation between an increasing number of events of AAAD and certain months within our catchment area and a significantly increased occurrence with rising temperatures (independent from absolute temperature at time of the event) in hypertensive patients
The impact of age and sex on in-hospital outcomes in acute type A aortic dissection surgery
Background: Older age and female sex are thought to be risk factors for adverse outcomes after repair of acute type A aortic dissection (AAAD). The aim of this study is to analyze age- and sex-related outcomes in patients undergoing AAAD repair.
Methods: Retrospective analysis of patients undergoing emergency AAAD repair. Patients were divided in Group A, patients aged ≥75 years and Group B <75. Intraoperative and postoperative data were compared between groups before and after propensity score matching. Sex differences were analyzed by age group.
Results: Between January 2006 and December 2018, 638 patients underwent emergency AAAD repair. Group A included 143 patients (22.4%), Group B 495 (77.6%). More patients in Group A presented with circulatory collapse (Penn C 26.6% vs. 9.7%, P=0.001) while Group B presented with circulatory collapse-branch malperfusion (Penn BC 29.3% vs. 15.4% P=0.001). After propensity score matching, Group B patients received more complex aortic root (33.6% vs. 23.2%, P=0.019) and concomitant bypass surgery (12.3% vs. 6.3%, P=0.042). There was no significant difference in in-hospital mortality between age groups (18% vs. 12% P=0.12). In Group B, in-hospital mortality was significantly higher in females (22.2% vs. 8.2%, P=0.028). Differences in mortality disappeared after the age of 75 (18.3% vs. 19.4% P=0.87).
Conclusions: Morbidity and mortality are comparable between patients under and over 75 years after AAAD repair. Female patients <75 had higher in-hospital mortality than their male counterparts.

Aorto-bronchial and aorto-pulmonary fistulation after thoracic endovascular aortic repair: an analysis from the European Registry of Endovascular Aortic Repair Complications
OBJECTIVES To learn upon incidence, underlying mechanisms and effectiveness of treatment strategies in patients with central airway and pulmonary parenchymal aorto-bronchial fistulation after thoracic endovascular aortic repair (TEVAR). METHODS Analysis of an international multicentre registry (European Registry of Endovascular Aortic Repair Complications) between 2001 and 2012 with a total caseload of 4680 TEVAR procedures (14 centres). RESULTS Twenty-six patients with a median age of 70 years (interquartile range: 60-77) (35% female) were identified. The incidence of either central airway (aorto-bronchial) or pulmonary parenchymal (aorto-pulmonary) fistulation (ABPF) in the entire cohort after TEVAR in the study period was 0.56% (central airway 58%, peripheral parenchymal 42%). Atherosclerotic aneurysm formation was the leading indication for TEVAR in 15 patients (58%). The incidence of primary endoleaks after initial TEVAR was n = 10 (38%), of these 80% were either type I or type III endoleaks. Fourteen patients (54%) developed central left bronchial tree lesions, 11 patients (42%) pulmonary parenchymal lesions and 1 patient (4%) developed a tracheal lesion. The recognized mechanism of ABPF was external compression of the bronchial tree in 13 patients (50%), the majority being due to endoleak formation, further ischaemia due to extensive coverage of bronchial feeding arteries in 3 patients (12%). Inflammation and graft erosion accounted for 4 patients (30%) each. Cumulative survival during the entire study period was 39%. Among deaths, 71% were attributed to ABPF. There was no difference in survival in patients having either central airway or pulmonary parenchymal ABPF (33 vs 45%, log-rank P = 0.55). Survival with a radical surgical approach was significantly better when compared with any other treatment strategy in terms of overall survival (63 vs 32% and 63 vs 21% at 1 and 2 years, respectively), as well as in terms of fistula-related survival (63 vs 43% and 63 vs 43% at 1 and 2 years, respectively). CONCLUSIONS ABPF is a rare but highly lethal complication after TEVAR. The leading mechanism behind ABPF seems to be a continuing external compression of either the bronchial tree or left upper lobe parenchyma. In this setting, persisting or newly developing endoleak formation seems to play a crucial role. Prognosis does not differ in patients with central airway or pulmonary parenchymal fistulation. Radical bronchial or pulmonary parenchymal repair in combination with stent graft removal and aortic reconstruction seems to be the most durable treatment strateg

How to make a “Heart Team” a “real” Team to ensure optimal patient care
Due to the ongoing ageing of the population with increased related co-morbidities, transcatheter interventions are spreading around the first world countries like an unstoppable firewall. Some (the tip of the iceberg) have already established in “normal clinical life” and became very safe procedures for the “modern high-risk patient” with acceptable outcomes over the last decade but many more are just evolving currently being under investigation with first in-man clinical trials
Der geeignete Zeitpunkt für eine Herzklappenintervention – Zusammenfassung der europäischen Richtlinien
Most common heart valve diseases in western industrialized nations are the aortic valve stenosis and the mitral valve regurgitation. More seldom are a regurgitation of the aortic valve and mitral valve stenosis. Even more seldom are heart valve diseases of the Tricuspid and the pulmonary valve. The only curative therapy in severe heart valve disease is a surgical intervention. The timing is crucial for the outcome. Especially in asymptomatic patients it's difficult to find the right point of time for intervention due to missing realization of the health status. In 2013, the European Association for Cardio-Thoracic Surgery (EACTS) and the European Society of Cardiology (ESC) published guidelines according to the therapy in heart valve disease. Here we want to summarize the recommendations of these guidelines in regards of timing of the surgical intervention
