Arterial switch operation in a neonate with simple transposition of great arteries.

Transposition of the great arteries (TGA) is characterized by severe and life-threatening hypoxemia during a newborn period. Without treatment, most of the patients die during early infancy. We reported a 20-day-old male newborn who was referred to our hospital due to severe cyanosis and respiratory distress. Echocardiograms revealed D-TGA with an intact ventricular septum. There was no pulmonary stenosis or other major cardiac anomalies. The cardiac catheterization and angiographic findings which were performed 4 days later were consistent with the diagnosis of echocardiography. The systolic left and right ventricular pressures were 65 and 69 mmHg respectively. Arterial switch operation was performed at the age of 28 days. Postoperative course was uneventful. The cardiac recatheterization and angiographic study performed 6 months after operation, and the latest non-invasive examination including chest X-ray, electrocardiogram and echocardiographic assessment revealed good ventricular performance and normal semilunar valve function. There was no obstruction at the anastomotic site. The patient has been doing well with regular follow-up at our clinic for 2 years and 6 months without medication.
