Comparative study of transcatheter aortic valve implantation versus conventional surgical aortic valve replacement in the treatment of severe aortic stenosis with reverse ventricular remodeling.

ABSTRACT:

Introduction

This study aimed to compare echocardiographic outcomes and analyze the changes in ventricular remodeling at different time points after surgery in patients with severe aortic stenosis (AS) undergoing either surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR).

Methods

This retrospective study consecutively enrolled 175 patients with severe AS who underwent either SAVR or TAVR. Transthoracic echocardiograms obtained at baseline, 30 days, and 1 year after the procedure were analyzed by multiple echocardiographers at our institution.

Results

At baseline, the TAVR group was significantly older (74 ± 7 years vs. 62 ± 9 years, p < 0.001) and had a higher prevalence of hypertension (53.5% vs. 31.0%, p = 0.003),
