Introduction
Indications for transcatheter aortic valve implantation (TAVI) are constantly expanding, including younger patients. Bicuspid aortic valves (BAV) often occur in this group. In order to achieve optimal treatment results in younger patients, it is necessary to develop an effective method for selecting the size of implanted valves. Aim: To compare the results of TAVI with use of a self-expanding prosthesis in patients with a BAV and a tricuspid aortic valve (TAV) with valve selection based on annular sizing.

Material and methods
The diagnosis of BAV and TAV and measurements (annular sizing) were based on multi-slice computed tomography scans. Eighty-three patients received a self-expanding CoreValve or Evolut R prosthesis. In group I (BAV) there were 21 (25.3%) patients and in group II (TAV) there were 62 (74.7%) patients.

Results
The groups did not differ in terms of baseline clinical characteristics. Device success was achieved in 16 (76.2%) and 55 (88.7%) (p = NS) in group I and II respectively. Composite endpoints: early safety occurred in 5 (23.8%) and 11 (17.7%) patients (p =NS) in group I and II respectively; clinical efficacy occurred in 10 (47.6%) and 28 (45.2%) patients (p = NS) in group I and II respectively. 30-day mortality was 4.8% vs 9.7%, 1-year mortality was 28.6% vs 17.7% (p = NS) in group I and II respectively.

Conclusions
TAVI in patients with severe aortic stenosis and BAV is as effective as in patients with TAV using self-expanding prostheses if the valve selection is based on annular sizing.
