Global longitudinal strain is associated with better outcomes in transcatheter aortic valve replacement.

ABSTRACT:

Background

Parameters that mark the timing of left ventricular (LV) reverse remodeling following transcatheter aortic valve replacement (TAVR) are incompletely defined. This study aims to identify the dynamics of LV strain derived from speckle tracking echocardiography in a cohort of patients with severe aortic stenosis (AS) who underwent TAVR and its correlation with postprocedural outcomes.

Methods

We selected 150 consecutive patients (82 ± 4 years old, STS score 6.4 ± 6.2) who underwent transfemoral TAVR between 07/2016 and 12/2017 at our tertiary care center. All patients were evaluated at baseline, 1 week after TAVR, and 3 months following TAVR.

Results

The global longitudinal strain (GLS) 1 week following TAVR was comparable to that at baseline (- 15,9 ± 4.3 vs
