Abstract
Despite the lack of randomized trials comparing transapical aortic valve implantation (TA-AVI) with surgical aortic valve replacement, there is consensus that the approach may be advantageous for a high-risk group of patients.1,2 Nevertheless, several complications are associated with TA-AVI. Paravalvular leak resulting in aortic insufficiency of grade II or more is reported at a high incidence3 and promotes left ventricular dysfunction, hemolysis, and endocarditis.4 The onset of atrioventricular block (AVB) is correlated with the implantation of large-diameter valves in patients with a small annulus diameter.
