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.
