Impact of annulus-cusp mismatch on mid-term outcomes of aortic valve repair with valve-sparing aortic root replacement.

ABSTRACT:

Objectives

This study aimed to investigate mid-term outcomes of aortic valve repair with valve-sparing aortic root replacement based on different grades of annulus-cusp mismatch and identify optimal aortic root geometries for this procedure.

Methods

A retrospective analysis was conducted between October 2011 and July 2022. Patients were stratified into three groups based on predicted coaptation length calculated using an annulus-cusp mismatch formula: no-mismatch (coaptation length > 4 mm, n = 52), mild-mismatch (2 mm ≤ coaptation length ≤ 4 mm, n = 28) and severe-mismatch (coaptation length < 2 mm, n = 25), and mid-term outcomes were compared.

Results

We included 105 patients who underwent valve-sparing root replacement using the reimplantation technique. During the
