Differences in Tricuspid Valve Insufficiency, Mechanical Synchrony, and Cardiac Remodeling Between Left Bundle Branch Area Pacing and Right Ventricular Pacing.
BACKGROUND Cardiac implantable electronic device-induced tricuspid regurgitation (CIED-induced TR) involves primary (lead-induced) and functional etiologies. The impact of left bundle branch area pacing (LBBAP) versus right ventricular pacing (RVP) on these mechanisms remains unclear. OBJECTIVE To compare the inciden...
