Three-Year Outcomes of Second Bioprosthesis After Early Surgical Aortic Bioprosthetic Failure.

ABSTRACT:

Background

Bioprosthetic valves are widely used in patients aged ≥65 years, but their durability is limited by structural valve deterioration (SVD). Data on repeat bioprosthetic aortic valve replacement (AVR) for early SVD (≤5 years) are scarce.

Objectives

The purpose of this study was to evaluate 3-year hemodynamic outcomes and the incidence of recurrent SVD following repeat AVR.

Methods

The authors retrospectively studied patients with surgical aortic valve replacement (SAVR) and early SVD requiring reintervention at Abbott Northwestern Hospital from January 2012 to December 2022. All patients had echocardiographic follow-up ≥30 days after repeat AVR. The primary endpoint was early SVD of the second bioprosthesis as per Valve Academic Research Consortium 3 criteria
