Transient RBBB and Temporary LBBB Following Transcatheter Aortic Valve Replacement

Year: 2025

Type: article

Abstract: BACKGROUND: Post-transcatheter aortic valve replacement (TAVR) conduction disturbances typically manifest as left bundle branch block (LBBB). Sequential right bundle branch block (RBBB) followed by LBBB is extremely rare. CASE SUMMARY: An 82-year-old female developed transient RBBB 1 hour after TAVR, followed by persistent LBBB 1 day later. Both conduction abnormalities resolved at the 1-month follow-up. CONCLUSIONS: New-onset RBBB may herald subsequent LBBB, warranting extended monitoring periods. TAKE-HOME MESSAGES: RBBB is uncommon after TAVR, but it should not be underestimated. In patients with RBBB following the procedure, prolonging the duration of temporary pacemaker implantation may be a prudent and clinically reasonable strategy.
