Bioprosthetic Valve Fracturing: In vitro Testing of Edwards PERIMOUNT Model P 2900.

ABSTRACT:

Background

Bioprosthetic valve fracturing (BVF) results in low gradients following valve-in-valve transcatheter aortic valve replacement (ViV-TAVR). For the commonly used Edwards PERIMOUNT valve data from bench-testing are lacking to provide technical specifications for successful BVF during ViV-TAVR.

Methods

Using four Perimount 19- and 21-mm valves, in-vitro high-pressure balloon valvuloplasty with the True Dilatation Balloon Valvuloplasty Catheter and Atlas Gold PTA Dilatation Catheter was performed to analyze balloon-oversizing and pressure-thresholds to successfully achieve BVF.

Results

High-pressure balloons one millimeter larger than the labeled valve size and pressure rates of 20 atm (for Perimount 19-mm) and > 22 atm (for Perimount 21-mm) were required
