Patients with congenital heart disease have unique pacing challenges and often require epicardial systems. High pacing threshold is one of the major factors that decrease these systems' durability. Sometimes surgical reintervention or lead replacement is difficult or prohibitive in these patients due to repeated surgeries and extensive epicardial scar. We present a case report of a patient with Fontan physiology and chronically high epicardial lead pacing thresholds requiring frequent generator changes and a unique solution focusing on improving generator longevity.
