Key result
Implantation of a leadless pacemaker in a heart transplant recipient with complete AV block resulted in no syncopal events or device-related complications over 5 years of follow-up.
Why the study?
Does leadless pacemaker implantation prevent syncope and avoid complications in a heart transplant recipient with complete AV block?

Does leadless pacemaker implantation prevent syncope and avoid complications in a heart transplant recipient with complete AV block?
Leadless pacemakers can be safely and effectively utilized in immunocompromised heart transplant recipients requiring pacing.
May support leadless pacing post-heart transplant; hypothesis-generating and requires validation in larger cohorts.
Our case demonstrates the safe and effective use of a leadless pacemaker in a heart transplant recipient. A man in his 60s with a history of heart transplantation with biatrial anastomosis 7 months prior presented to the emergency department after several syncopal episodes. Telemetry monitoring revealed a paroxysmal complete atrioventricular block. Given his immunocompromised state and prior dual chamber pacemaker extraction at the time of heart transplantation, the patient underwent successful implantation of a leadless pacemaker. Over the past 5 years since device implantation, the patient has not had any syncopal events nor has he had any device-related complications, such as infection.

Yan et al. (2023) conducted a case report in Heart transplantation with paroxysmal complete atrioventricular block (n=1). Leadless pacemaker was evaluated on Syncopal events and device-related complications. Implantation of a leadless pacemaker in a heart transplant recipient with complete AV block resulted in no syncopal events or device-related complications over 5 years of follow-up.
