Novel Lithotripsy-Assisted Transcatheter Aortic Valve Replacement May Reduce Risk of Aortic Root Rupture.

ABSTRACT:

Background

Severe calcific aortic stenosis (AS) can be successfully treated with transcatheter aortic valve replacement (TAVR) using both balloon-expandable valves (BEV) and self-expanding valves. Challenges remain for treatment of AS with TAVR in relation to the severity of calcification involving valve leaflets, aortic annulus, and/or left ventricular outflow tract. Severe calcification presents challenges to TAVR with respect to aortic root/annular rupture and risk for peri-valve leak (PVL).

Methods

Three separate patients with symptomatic severe AS and severely calcified valves underwent TAVR with BEV. Case 1 underwent TAVR without preceding intravascular lithotripsy (IVL) of the native valve and developed annular rupture requiring surgical rescue. Following this experie
