Transcatheter aortic valve replacement (TAVR) induced pathological damage in cardiac conduction system leads to symptomatic bradycardia and electric dyssynchrony such as left bundle branch block (LBBB) is associated with an increased risk for heart failure. Left bundle branch pacing (LBBP) has emerged as an alternative method for delivering physiological pacing to achieve electrical synchrony of the left ventricle. We report a case of heart failure patient with new onset LBBB (NO‐LBBB) induced by TAVR, LBBP corrected the NO‐LBBB and reversed the heart function with stable capture and correction threshold.
