A new wearable e monitoring technology for evaluation of left ventricular remodeling after transcatheter aortic valve replacement.

ABSTRACT:

Aims

Pathological left ventricular (LV) remodelling following aortic stenosis (AS) confers high risk for heart failure and significantly decreases survival. This study aims to introduce a new wearable acoustic cardiography (ACG) device measuring electromechanical activation time (EMAT) to identify the regression of cardiac remodelling in AS patients undergoing transcatheter aortic valve replacement (TAVR).

Methods and results

This prospective cohort study consecutively enrolled patients with severe symptomatic AS who underwent successful TAVR. The parameters EMAT and EMAT% (EMAT divided by R-R interval, expressed as a percentage) derived from ACG as well as echocardiography data were collected. Pearson correlation analysis was performed to evaluate the correlation between EM
