Does left bundle branch area pacing (LBBAP) improve LVEF and suppress ectopy in a patient with LBBB-induced cardiomyopathy?
LBBAP may effectively reverse mechanical dyssynchrony and suppress high burdens of atrial and ventricular ectopy in patients with LBBB-induced cardiomyopathy.
ABSTRACT Left bundle branch area pacing (LBBAP) is an effective strategy for restoring electro mechanical synchrony; however, its potential to suppress a high burden of concomitant atrial and ventricular ectopy remains to be fully elucidated. We present a 57‐year‐old male patient with left bundle branch block (LBBB)‐induced cardiomyopathy who experienced significant improvement in left ventricular ejection fraction (LVEF) and marked suppression of both premature ventricular contractions (PVCs) and supraventricular extrasystoles (SVEs) after LBBAP. At 6 months of follow‐up, LVEF increased to 58%, PVCs decreased to 200 per day, and SVEs disappeared. LBBAP can reverse mechanical dyssynchrony and suppress a high burden of ectopy.
Dural et al. (Sat,) conducted a case report in Left bundle branch block (LBBB)-induced cardiomyopathy (n=1). Left bundle branch area pacing (LBBAP) was evaluated on Left ventricular ejection fraction (LVEF) and burden of premature ventricular contractions (PVCs) and supraventricular extrasystoles (SVEs). Left bundle branch area pacing in a patient with LBBB-induced cardiomyopathy increased LVEF to 58% and markedly suppressed premature ventricular contractions and supraventricular extrasystoles.
