Aortic Root Enlargement in patients with small aortic annulus undergoing double valve replacement. A retrospective Comparative cohort study

Abstract: Objectives Small Aortic Annulus (AA) is big issue during Aortic Valve Replacement (AVR) necessitating replacement of inappropriate-sized prostheses especially during Double Valve Replacement (DVR). Despite that small aortic valve prostheses can lead to Prosthesis-Patient Mismatch (PPM), there remains reluctance to perform aortic root enlargement (ARE) procedures fearing from morbidity and mortality. We evaluate clinical and echocardiographic outcomes in patients with small AA undergoing DVR. Methods The stud… Show more

“…The inclusion criteria for the study were adults of either gender, aged greater than 16 years, who underwent AVR alone or in combination with ARE, and who had a left ventricular ejection fraction (LVEF) greater than 30%. Exclusion criteria were set to omit patients older than 70 years and those with chronic kidney disease (CKD), aiming to minimize confounding factors that could influence the outcomes of interest (19). For the analysis of the collected data, the Statistical Package for the Social Sciences (SPSS) version 26.0 (IBM-SPSS Inc., Chicago, USA) was employed.…”
