Introduction:
Among anatomical factors affecting transcatheter aortic valve implantation (TAVI)
success, aortic annulus shape plays a relevant role; an elliptic geometry may lead to gaps
between the aortic root and the prosthesis which are designed to expand circularly,
resulting in paravalvular leak (PVL). In this context, the impact of different self-expanding
(SE) devices is currently unknown.
Aim of the study was to compare PVL and device success rates of Portico and Evolut-R in
patients with elliptic aortic annulus and to test by computational simulations their behavior
by increasing eccentricity.
