Key result
LBBP corrects TAVR-induced new-onset LBBB and reverses heart function in a case report.
Why the study?
TAVR-induced left bundle branch block causes electrical dyssynchrony and increases heart failure risk, and methods to correct this are needed.
Does left bundle branch pacing correct TAVR-induced new-onset LBBB and reverse heart failure?

Does left bundle branch pacing correct TAVR-induced new-onset LBBB and reverse heart failure?
Left bundle branch pacing can successfully correct TAVR-induced new-onset LBBB and reverse subsequent heart failure.
LBBP may restore synchrony in post-TAVR LBBB HF; hypothesis-generating and requires prospective trials before any practice change.
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.

Zhang et al. (2020) conducted a case report in Heart failure with new-onset left bundle branch block induced by TAVR (n=1). Left bundle branch pacing (LBBP) was evaluated on Correction of NO-LBBB and reversal of heart function. Left bundle branch pacing successfully corrected new-onset left bundle branch block induced by TAVR and reversed heart function with stable capture and correction threshold.
