Initial findings using the V8 hourglass-shaped valvuloplasty balloon for postdilatation in treating paravalvular leaks associated with transcatheter self-expanding aortic valve prosthesis.

Objectives: The aim of this study was to assess the effect of a novel hourglass-shaped balloon on reduction of paravalvular leak (PVL) in patients undergoing transcatheter aortic valve replacement (TAVR) with self-expanding prostheses.

Background: An important limitation of TAVR compared with surgical aortic valve replacement remains the higher incidence of PVL. A commonly used strategy to treat PVL is balloon postdilatation (BPD); however, the optimal technique for treating PVL after TAVR is unknown.

Improvement in aortic valve area using a new "hour glass" shaped valvuloplasty balloon compared with standard cylindrical balloons in severe aortic stenosis patients.

Aim: Balloon aortic valvuloplasty (BAV) has reemerged with transcatheter valve therapy. Cylindrical balloons have been the device of choice despite limitations. An hour glass shaped balloon may permit enhanced fixation and broader leaflet opening without annular compromise.
