Fistula Into the Left Atrium After Atrial Septal Defect Closure

A 4-YEAR-OLD boy (weight: 13 kg; height: 98 cm) underwent surgical closure of a very large atrial septal defect (2.72 cm; Fig 1, A and B; Video 1). The aortic rim of the septal defect was deficient (Fig 2, Video 2). Both atrioventricular valves were competent. The aortic valve and proximal aorta appeared normal. All the pulmonary veins were draining into the left atrium, and the coronary sinus was of normal size. After separation from cardiopulmonary bypass, the 4-chamber transesophageal echocardiography view showed complete closure of the defect (Video 3).
