Right atrial isomerism with infracardiac total anomalous pulmonary venous connection complicated by hiatal hernia

Abstract

A 31-day-old girl with right atrial isomerism, a single atrium, a single right ventricle, pulmonary atresia, patent ductus arteriosus, coarctation of the pulmonary artery, infracardiac total anomalous pulmonary venous connection, and a large hiatal hernia was referred to our institution. We successfully performed a first-stage open palliation comprising the creation of a systemic-to-pulmonary arterial shunt, pulmonary artery angioplasty, and correction of the total anomalous pulmonary venous connection. During cardiopulmonary bypass, the hiatal hernia was also repaired through the median sternotomy itself without another laparotomy. The postoperative course was uneventful, and we avoided the potential complications of pulmonary venous obstruction and enteral feeding. She underwent a bidirectional Glenn operation and Fontan completion at 5 and 19 months of age, respectively.
