BACKGROUND: Little is known about temporary Left Bundle Branch Block (LBBB) after transcatheter aortic valve replacement (TAVR). We aim to evaluate the incidence, prognostic impact and predictors of temporary LBBB in TAVR patients.
METHODS: Electrocardiograms (ECGs) obtained before and after TAVR, at discharge and at 30-day follow-up were anonymously analyzed by 5 cardiologists. Temporary LBBB included transient LBBB or persistent LBBB. The primary endpoint was all-cause mortality at 1-year after TAVR.
RESULTS: Out of 198 patients, 55 (27.7%) developed temporary LBBB. No differences between groups were observed in primary endpoint. Left ventricular ejection fraction (LVEF) was identified as predictive factor of transient LBBB.
CONCLUSIONS: Temporary LBBB has no significant impact on survival at 1 year after the procedure.
