This report describes an 8 day old infant with pulmonary valve atresia, hypoplastic and hypertensive right ventricle and myocardial sinusoid-left anterior descending coronary artery connections. A large right ventricular sinusoid complex developed that was associated with transmural right ventricular necrosis and cardiac rupture. This is the first report to document transmural myocardial infarction and rupture in pulmonary valve atresia with intact septum, and this condition should be added to the causes of myocardial infarction in infancy. A reduced number of caliber of sinusoid-coronary artery channels may be responsible for right ventricular damage in this condition.
