Abstract
A 63-year-old male with prior aortic valve replacement and Bentall procedure for E. faecalis endocarditis developed paroxysmal atrioventricular (AV) block after repeat Bentall surgery. Telemetry demonstrated PVC-triggered phase 4 block leading to high-grade AV block, prolonged pauses, and polymorphic ventricular tachycardia. A temporary permanent pacemaker was implanted, followed by ventricular leadless pacemaker placement. This case highlights the malignant potential of phase 4 block, particularly when combined with postoperative conduction system disease, and underscores the importance of early recognition and pacing support.
