Transvenous dual‐chamber pacemaker after paediatric heart transplantation using left ventricle pacing through the coronary sinus

摘要

A 12‐year‐old child with end‐stage heart failure due to restrictive cardiomyopathy was submitted to orthotopic heart transplantation. Primary graft dysfunction required venous arterial extra‐corporeal membrane oxygenation. Heart function normalized, but complete atrioventricular block remained after 3 weeks. A dual‐chamber pacing with transvenous left ventricle pacing through the coronary sinus was performed. At 5‐year follow‐up, the patient is stable with the same pacing system and with preserved ventricular function.
