Why the study?
Left bundle branch area pacing is a novel conduction system pacing technique, but procedural success, safety, and preoperative predictors of procedural failure required evaluation.
What are the predictors of procedural failure for left bundle branch area pacing in patients with bradycardia?
What are the predictors of procedural failure for left bundle branch area pacing in patients with bradycardia?
Thickened interventricular septum, severe tricuspid regurgitation, and intraventricular conduction delay are significant preoperative predictors of LBBAP implantation failure.

May inform preprocedural risk stratification for LBBAP; hypothesis-generating and requires prospective validation before guiding practice.
