Abstract

Left ventricular inflow obstruction can be caused by a persistent left superior vena cava (SVC) and a dilated coronary sinus. A 31-day-old male infant with secondum atrial septal defect (ASD) and bilateral SVC underwent an operation for treating his uncontrollable congestive heart failure. The preoperative 2-dimensional echocardiography showed a normally sized mitral valve shrouded by a dilated coronary sinus. The operation consisted of pericardial patch closure of the ASD, coronary sinus unroofing and left SVC transfer to the right atrial auricle. The postoperative course was complicated by persistent chylothorax, which was controlled by thoracic duct ligation. He was discharged to home at the postoperative day 39. He has been followed up for 9 months and has displayed normal development.
