End-systolic septal strain and reverse remodeling after cardiac resynchronization therapy (CRT). a The end-systolic septal strain (ESSsep) parameter at baseline is strongly related with LV end-systolic volume (LVESV) change after CRT implantation. b ESSsep shows good predictive value for CRT response (≥ 15% LVESV reduction) as demonstrated by receiver operating characteristic (ROC) curve analysis
