Brief Summary

The primary hypothesis of the proposed study is that an electrophysiology-based algorithmic approach is superior to standard clinical follow-up with 30-day monitoring in reducing the combined endpoint of syncope, hospitalization, and death in patients in patients with new of left bundle branch block following transcatheter aortic valve implantation (TAVI).

Eligibility Criteria

Inclusion Criteria: * Age ≥18 years * Informed consent to participate * Persistent new-onset LBBB after TAVI implantation (i.e. present at day 2) Exclusion Criteria: * Prior pacemaker or implantable cardioverter-defibrillator * Pre-existing right bundle branch block (RBBB) or LBBB (i.e., prior to TAVI) * Class I or IIA indication for PPM implantation according to management guidelines
