Tricuspid regurgitation outcomes in left bundle branch area pacing and comparison with right ventricular septal pacing

Tricuspid regurgitation (TR) is a known complication of cardiac implantable electrical devices. Theoretically, lead-related TR risk in patients with left bundle branch area pacing (LBBAP) should be lower than in patients with right ventricular (RV) septal pacing because of the thinner pacing lead and physiological pacing effect. This study aimed to assess lead-related TR outcomes of LBBAP and compare LBBAP and RV septal pacing in patients with bradycardia.
