Objectives: Transcatheter Aortic Valve Implantation (TAVI) has become a well accepted treatment option for patients at high risk for standard aortic valve replacement. The logistic EuroSCORE is generally used to select patients. Previous cardiac surgery is one EuroSCORE factor, as it is considered to be a risk factor for mortality, particularly if the patients has patent bypass grafts. We analyzed, whether previous cardiac surgery is also a risk factor for patients undergoing TAVI.

Methods: Between 5/2000 and 9/2012 146 patients underwent transapical catheter based aortic valve replacement. 43 valves (Group 1) were redos, 103 (Group 2) primary operations. Mean age was 75.8 ± 9.6 years (Group 1), and 82.0 ± 7.6 years (Group 2). Mean logistic EuroSCORE was 29.5 ± 18.6% (Group 1), and 24.0 ± 15.5% (Group 2), respectively.

Results: 30-day survival was 95.5% in Group 1, and 93.1% in Group 2. 1-year survival was 88.3% in Group 1, and 78.5% in Group 2. 3-year survival was 70.9% in Group 1, and 66.5% in Group 2 (p > 0.63). Kaplan-Meier curves are shown in Figure 1.

Conclusions: Previous cardiac surgery does not increase mortality of TAVI, although patients generally present with higher EuroSCOREs.
