Abstract

Transcatheter aortic valve replacement (TAVR) has evolved into a routine procedure with good outcomes in high-risk patients. TAVR complication rates were evaluated based on prospective data from the German Aortic Valve Registry (GARY). From 2011 to 2013, a total of 15,964 TAVR procedures were registered. We evaluated the total cohort for severe vital complications (SVCs), including the following: death on the day of intervention, conversion to sternotomy, low cardiac output that required mechanical support, aortic dissection, and annular rupture; technical complications of the procedures (TCOs), such as repositioning or retrieval of the valve prosthesis and embolization of the prosthesis; and other complications. Mean patient age was 81 ± 6 years, 54% of the patients were women, the median logistic Euroscore I was 18.3, the German aortic valve score was 5.6, and the Society of Thoracic Surgeons score was 5.0. Overall in-hospital mortality was 5.2%, whereas SVCs occurred in 5.0% of the population. Independent predictors for SVCs were female sex, pre-operative New York Heart Association functional class IV, ejection fraction <30%, pre-operative intravenous inotropes, arterial vascular disease, and higher degree of calcifications. TCOs occurred in 4.7% of patients and decreased significantly from 2011 to 2013. An emergency sternotomy was performed in 1.3% of the patients; however, multivariate analysis did not identify any predictors for conversion to sternotomy. The all-comers GARY registry revealed good outcomes after TAVR and a regression in complications. Survival of approximately 60% of patients who experienced SVCs or who required sternotomy underlines the need for heart team–led indication, intervention, and follow-up care of TAVR patients.
