Background: We determined our 30-day results after transapical aortic valve implantation (TA-AVI) according to Valve Academic Research Consortium criteria, analyzed midterm outcome, and summarize our institutional learning experience. Methods: From February 2008 to July 2011, 150 high-risk patients underwent TA-AVI. Endpoints of this retrospective analysis were safety as indicated by morbidity and 30-day mortality and midterm survival with a follow-up period up to 3.4 years (mean follow-up 14.1 months). In addition we analyzed our institutional learning curve by comparing the outcome of our first 50 patients (group 1) to the following 100 patients (group 2). Results: Procedural success was 98% (147 patients). All-cause and cardiovascular cause 30-day mortality was 11.3% (n = 17) and 7.3% (n = 11), respectively. The cumulative survival rates were 78.7% at one year, 62.8% at two years, and 50.8% at three years. As compared to group 1, there was a significantly reduced incidence of relevant bleeding complications (0% vs. 14%[n = 7]; p < 0.001) and a reduced incidence of acute kidney injury (35%[n = 35] versus 56% (n = 28); p < 0.05) in group 2, resulting in a combined safety endpoint at 30 days of 22% in group 2 versus 40% in group 1 (p < 0.05). One-year mortality (group 2, n = 20 [20%] versus group 1, n = 10 [20%]; p = 1) and midterm survival (p = 0.998; Hazard ratio 1.001; 95% CI 0.5141 to 1.949) did not differ significantly. Conclusions: Although the incidence of technical complications decreased significantly over time, 30-day and midterm mortality were unaltered, most likely due to patients' comorbidities. The development of more accurate risk scores may improve future outcome. (J Card Surg 2012;27:653-661)
