Reverse electrical remodelling after cardiac resynchronization therapy in a patient undergoing left bundle branch area pacing: a case report

This case demonstrates that LBBAP can induce reverse electrical remodelling, even in the presence of distal conduction system disease. With the current availability of different pacing strategies in CRT (i.e. biventricular CRT, LBBAP, and left bundle branch-optimized CRT), more research on patient selection and pacing strategy selection is needed.
