Cardiac transplant-associated complete AV block treated with a leadless pacemaker: a case report.

ABSTRACT:

Background

Complete atrioventricular (AV) block is a rare complication immediately following orthotopic heart transplantation (OHT), typically attributed to ischaemic injury or surgical trauma. In immunosuppressed patients, pacemaker selection requires careful consideration due to heightened infection risk.

Case summary

We present a 48-year-old woman with hypertrophic cardiomyopathy who developed persistent complete AV block with no ventricular escape following OHT. The early postoperative period was complicated by right ventricular failure and severe systemic infections. After stabilization, on Day 32 post-transplant, a Micra AV2 leadless pacemaker was implanted due to high infectious risk and presence of moderate-to-severe tricuspid regurgitation. The procedure was success
