Impact of left ventricular lead position in cardiac resynchronization therapy on left ventricular remodelling. A circumferential strain analysis based on 2D echocardiography

Abstract

Detailed analysis of the myocardial contraction sequence using circumferential strain imaging allows determination of the LV lead position in CRT. Optimal LV lead position in CRT defined by circumferential strain analysis results in greater improvement in LV function and more LV reverse remodelling than non-optimal LV lead position.
