title: Sudden death due to ventricular septal defect.
abstract: Ventricular septal defects (VSD) are usually considered non-life-threatening, usually closing spontaneously or causing symptoms of congestive heart failure, which can be surgically treated in time to save the patient's life. Despite the usually benign clinical course of VSD, serious arrhythmias occur in 16-31% of patients. Sudden death accounted for one-third of all deaths in a series of medically managed patients and occurred in 4.2% of patients in a study of VSD and arrhythmias. Cardiac hypertrophy is the common denominator in all cases reported in detail of VSD-associated sudden death. We have encountered four cases of sudden unexpected death from VSD in infants ranging in age from 1 week to 3 and (1/2) months. In each case there was cardiomegaly and in one case there was pulmonary arteriolar medial thickening, with extension of smooth muscle into small intralobular vessels. In half of our cases the attending physician was sued for malpractice. We believe that VSD in infants and young children are potentially life-threatening malformations which warrant careful clinical follow-up.
