Objective To review and summarize the clinical outcomes of neonatal D-transposition of the great arteries by rapid two-stage arterial switch operation. Methods Between September 2002 and May 2003, five neonates with D-transposition of the great arteries were repaired by rapid two-stage arterial switch operation. The operative age was 83.0±72.2 day and weight was 4.7±0.9 kg. Because these patients came to the hospital late, the left ventricle was unable to accommodate the systemic pressure, so the left ventricle had to be prepared by pulmonary artery banding and systemic-pulmonary arterial shunt. After 6-9 days, the arterial switch procedure was performed. Results At first stage, one patient died of supraventricular tachycardia and oliguria after peritoneal dialysis. Four patients were repaired by arterial switch operation with no death. These patients were followed up for 2 to 10 months and had good development. The echocardiogram showed that there were no intracardiac residual shunt , the aorta and pulmonary artery anastomosis had no obstruction . The heart function was good, ejection fraction 0.68-0.77,fractional shortening 0.24-0.37. One patient had mild aortic valve regurgitation. Conclusion Rapid two-stage arterial switch operation is the best way for neonatal D-transposition of the great arteries that the left ventricle was unable to accommodate the systemic pressure.
