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

Abstract

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.
