Cardiac Implantable Electronic Devices in Cardiac Transplant Patients: A Comprehensive Review.

A fraction of patients (approximately 10%) undergoing heart transplantation require permanent pacemaker (PPM) implantation due to sinus node dysfunction or atrioventricular block, occurring either shortly after surgery or later. The incidence of PPM implantation has declined to less than 5% with the introduction of bicaval anastomosis transplantation surgery. Pacing dependency during follow-up varies among recipients.
