This is a 3. 3 kg, male neonate who was born with a prenatal diagnosis of dextro-transposition of the great arteries (d-TGA) and intact ventricular septum. At birth, he was deeply cyanotic and was intubated and prostaglandin infusion was initiated to maintain ductal patency. Transthoracic echocardiogram confirmed the prenatal diagnosis and normal coronary pattern for d-TGA (1 LCx, 2RCA). Due to restricted atrial communication, a bedside echo-guided balloon atrial septostomy was performed. He was subsequently extubated and weaned off prostaglandins.

On day of life 9, he was taken to the operating room for an arterial switch operation with Lecompte maneuver, ligation and division of the ductus arteriosus and closure of the atrial septal defect.

The procedure was performed via median sternotomy with aortic and single right atrial cannulation at 32 degrees celsius. A left atrial line was placed through the left atrial appendage. Intraoperative fluorescent angiography with indocyanine green confirmed excellent flow in all epicardial coronary arteries and good myocardial perfusion. Chest was closed and the patient was extubated in the operating room. Left atrial line was removed 48 hours later with subsequent wean of inotropic and pressor support. Chest tubes were removed on the third postoperative day. He experienced a short episode of supraventricular tachyarrhythmias which was controlled medically, otherwise the remaining part of his postoperative course was uneventful and he was transferred to the ward on the fifth postoperative day and was discharged eight days after his arterial switch.

Pre-discharge transthoracic echocardiogram showed good biventricular function, no atrial level shunt, widely patent both right and left ventricular outflow tracts, and competent neo-aortic and neo-pulmonary valves. He continued to do well during his follow-up.
