Mechanical circulatory support to control medically intractable arrhythmias in pediatric patients after cardiac surgery.

Postoperative intractable arrhythmia can result in high morbidity and mortality. This report describes our experiences using mechanical circulatory support (MCS) to control medically intractable arrhythmias in three pediatric patients with congenital heart disease (CHD), after palliative or total corrective open-heart surgery.
