Abstract
Transcatheter aortic valve implantation (TAVI) is considered the standard of care for patients with severe symptomatic aortic stenosis unsuitable for surgery. However, short- and long-term mortality after TAVI are still relatively high. The aim of this study was to establish survival, predictive factors, and causes of mortality after TAVI at early and midterm follow-up. Between December 2007 and May 2012, a total of 119 patients with symptomatic severe aortic stenosis underwent 121 TAVI procedures. The mean ± SD age was 81 ± 9 years, and 59% were men. The mean ± SD logistic European System for Cardiac Operative Risk Evaluation was 22 ± 15. Seventy-five patients (63%) were in New York Heart Association functional class III to IV. The transfemoral approach was used in 76% of the patients. One hundred ten patients (91%) had the CoreValve prosthesis, and 11 (9%) had an Edwards SAPIEN valve. Baseline characteristics, procedural complications, and outcomes were collected prospectively. Clinical outcomes were defined according to the Valve Academic Research Consortium criteria. Follow-up was completed for 100% of the patients at a median of 1.3 years (range, 0-4.5). The total number of deaths was 36 (30%). One-month mortality was 4.2%...Continue Reading
