Prognostic value of left atrioventricular coupling index in patients undergoing transcatheter aortic valve implantation: a prospective echocardiographic study.

ABSTRACT:

Background

Transcatheter aortic valve implantation (TAVI) is an alternative procedure for patients with symptomatic aortic stenosis who are not suitable candidates for open-heart surgery. Preoperative left ventricular diastolic function influences TAVI outcomes. The left atrioventricular coupling index (LACI) is a novel prognostic indicator in cardiovascular research that is significantly correlated with left ventricular diastolic function. Its role in TAVI remains unclear. The aim of this study was thus to investigate the prognostic value of the echocardiography-derived LACI in predicting major adverse cardiac events (MACEs) after TAVI.

Methods

This study included patients with moderate-to-severe aortic stenosis undergoing TAVI (June 2021-December 2024). Preoperative transt
