Impact of valvuloarterial impedance on 2-year outcome of patients undergoing transcatheter aortic valve implantation.

Abstract

BACKGROUND Elderly patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) often have increased calcification and fibrosis of the aorta. Indices that account for the severity of valvular obstruction and systemic vascular impedance may better assess total left ventricular afterload. The aims of the present study were to… (More)
