Graphical Abstract

Cardiac magnetic resonance–derived myocardial scar predicts response of cardiac resynchronization therapy via left bundle branch area pacing. Baseline electrocardiogram morphology and pre-procedural scar evaluation from cardiac magnetic resonance predict reverse remodelling after left bundle branch area pacing for cardiac resynchronization therapy. Low global, septal, and lateral scar burden helps to identify more responders on top of Strauss left bundle branch abnormality.
