Abstract

Introduction: Transcatheter aortic valve implantation (TAVI) is a less invasive treatment option for elderly, high-risk patients with symptomatic severe aortic stenosis (AS) than aortic valve replacement. More importantly, TAVI improves survival and quality of life as compared to medical treatment in inoperable patients.

Aim: To assess early- and mid-term clinical outcomes after TAVI.

Material and methods: All consecutive high-risk patients with severe symptomatic AS undergoing TAVI from November 2008 to August 2014 were enrolled. The clinical and procedural characteristics, as well as clinical outcomes including mortality during 12-month follow-up, were assessed.

Results: A total of 101 consecutive patients underwent TAVI for native aortic valve stenosis (100%). Patients were elderly, with a median age of 81.0 (76.0-84.0) years, 60.4% were female and 83.2% presented with NYHA III/IV. Median baseline EuroSCORE I and STS scores were 14.0 (10.0-22.5)% and 12.0 (5.0-24.0)%, respectively. The main periprocedural and in-hospital complications were minor vascular complications, bleeding requiring blood transfusions, and the need for a permanent pacemaker. In-hospital, 30-day, 6-month and 12-month mortality rates were 6.9%, 10.9%, 15.8% and 17.8%, respectively.

Conclusions: A mortality rate of < 20% after 12 months seems acceptable given the high-risk population enrolled.
