Transcatheter aortic valve implantation (TAVI) is an emerging technique for the treatment of severe symptomatic aortic stenosis. Little has been reported about the use of different devices and multiple catheter-based options and anesthetic techniques in the same institution. We report the long-term clinical experience in treating patients with severe symptomatic aortic stenosis using TAVI. We analyzed the outcomes of 153 TAVI-treated patients who were followed for ≤2 years. All patients were at very high risk of surgical valve replacement. The Medtronic-CoreValve device was used in 59.5% and the Edwards-SAPIEN device in 40.5% of the patients. The primary end point was death from any cause during follow-up. The mean ± SD patient age was 81.1 ± 6 years, and 62% of the patients were women. The procedural success rate was 97.4%. At 30 days of follow-up, the all-cause mortality was 3.9%. Two-year follow-up data were obtained for 108 patients, with 85.5% survival of treated patients. The 30-day stroke rate was 3.9%. No significant differences in mortality were found when angioplasty was performed before or during TAVI compared with TAVI alone. Multivariate analysis showed that increased baseline creatinine (hazard ratio 1.55, 95% confidence interval 1.01 to 2.42, p = 0.049) and increased logistic European System for Cardiac Operative Risk Evaluation score (hazard ratio 1.03, 95% confidence interval 1.01 to 1.06, p = 0.048) predicted all-cause mortality. In conclusion, the clinical outcome of TAVI is favorable. The use of both procedural devices and multiple techniques in the same institution is feasible and potentially desirable.
