OBJECTIVES: To evaluate balloon-expandable and self-expanding third-generation transcatheter aortic valve replacement (TAVR) devices according to patient selection criteria and outcomes.

RESULTS: 74 patients received a self-expanding valve (SEV) and 183 received a balloon-expandable valve (BEV). Patients selected for SEV were more frequently women, with lower body surface area and smaller calcified iliofemoral arteries. Three SEV patients required implantation of a second valve to successfully treat paravalvular leak. Only one BEV patient had moderate paravalvular regurgitation. There was no difference in the rate of stroke, major vascular complication or bleeding.
