[Transcatheter aortic valve implantation: results of a new therapeutic option for high surgical risk aortic stenosis].

INTRODUCTION Transcatheter aortic valve implantation (TAVI) is an alternative to surgical aortic valve replacement in patients with severe aortic stenosis (AS) and unacceptably high surgical risk. METHODS We present our first two years' experience with TAVI. A total of 76 AS patients were evaluated for TAVI and 23 of them underwent a TAVI procedure. These patients had a mean EuroSCORE of 22.4% and a mean age of 81.5 years, and were prospectively followed for a mean of 12.9 ± 11 months. RESULTS The percutaneous aortic valve was successfully implanted in 100% of the patients. Mortality at 30 days was 4%. The most common complications were access site-related bleeding and transfusion (22%), followed by new permanent pacemaker implantation (9%). After a mean follow-up of 12.9 months, survival was 87%. In a maximum follow-up of 30 months there were no cases of prosthesis dysfunction or cardiovascular death. CONCLUSIONS Two years after the introduction of a TAVI program in our center, the procedure has established itself as a safe and effective alternative for patients with severe AS and unacceptably high surgical risk.
