Abstract:
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.

Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...
