Bioprosthetic Valve Fracturing in Valve-in-Valve TAVI: Clinical and Echocardiographic Outcomes in Failing Perimount Aortic Bioprostheses-A Multicenter Registry.

ABSTRACT:

Background

Data comparing clinical and hemodynamic outcomes of bioprosthetic valve fracturing (BVF) and "standard"-postdilatation during valve-in-valve transcatheter heart valve implantation (ViV-TAVI) are lacking. The authors aimed to analyze hemodynamic and clinical outcomes of BVF compared to "standard"-postdilatation during ViV-TAVI.

Methods

The REDUCE registry included patients who underwent ViV-TAVI within a Perimount surgical aortic valve bioprosthesis (Edwards Lifesciences, USA). Procedures were categorized to no postdilatation, "standard"-postdilatation and BVF. Hemodynamic and clinical outcomes at 30 days were collected and compared. A linear regression model was built to predict mean aortic gradient after ViV-TAVI.

Results

A total of 240 patients from six E
