Trends and Outcomes of Aortic Root Enlargement During Bioprosthetic Aortic Valve Replacement.

ABSTRACT:

Background

Aortic root enlargement (ARE) during aortic valve replacement (AVR) mitigates prosthesis-patient mismatch, but its use has been low. Transcatheter aortic valve-in-valve (VIV) as a treatment for failing bioprosthetic valves is limited by small surgical valves, renewing interest in ARE during the index AVR. This study demonstrates trends and outcomes of ARE after commercial approval of VIV in 2015.

Methods

This retrospective cohort study analyzed 2182 patients undergoing nonemergent AVR between August 2007 and December 2022. Endocarditis, aortic dissection, and concomitant root replacement or ventricular assist device placement were excluded. Trends in ARE use, valve size, and types were compared. Outcome measures included 30-day mortality and gradients and were com
