Abstract
This report describes 2 patients with hypoplastic left heart syndrome who developed severe coarctations of the aorta after Norwood Stage I procedures and subsequently survived recurrent ventricular fibrillation during successful percutaneous angioplasty. Although ventricular fibrillation has not been associated with hypoplastic left heart syndrome, postoperative Norwood Stage I, or angioplasty of isolated coarctations of the aorta, we believe that the complex physiology of our patients created conditions that precipitated ventricular tachycardia and ventricular fibrillation. We strongly recommend that follow-up of infants with hypoplastic left heart syndrome after Norwood Stage I operations be meticulous; that even mild coarctation be treated aggressively, to avoid progression to high-risk situations; and that interventionalists be prepared to manage malignant ventricular dysrhythmias whenever postoperative Norwood Stage I patients undergo percutaneous angioplasty for coarctation of the aorta.
