Sutureless valves versus aortic root enlargement for aortic valve replacement in small aortic annulus: A systematic review and pooled analysis.

Abstract

Very few studies provide direct comparisons between aortic root enlargement and sutureless valve implantation in patients with a small aortic annulus who underwent aortic valve replacement. This study aims to provide comparative outcomes between the two in such a subset of patients, through a systematic review and pool analysis.
