Sixty four children(aged 2 days to 9 years), 58 with complete transposition of the great arteries, 5 with Taussig-Bing double outlet right ventricle. and 1 with double outlet left ventricle plus left ventricular type single ventricle, have
undergone
anatomic correction from November 1987 to August 1992.
@ES Eleven underwent previous operations:
@EN pulmonary artery banding(7), modified Blalock-Taussig shunt(2), coarctoplasty(2), aortic arch reconstruction(1). Of 58 patients with TGA, Type A coronary arteries of Yacoub classification were seen in 50(86%). U-shaped coroanry arterial flaps
were
transfered to the neoaorta using trap door technique, and neopulmonary arterial tract was constructed using glutaraldehyde fixed autopericardium with Lecompte maneuver.
There were 18 hospital deaths (28.1%) with no late mortality. Mean follow-up of 20.4*11.9 months were achieved in all survivors. Postoperative cardiac catheterizations were done in 14 cases. Mean pressure gradients of pulmonary and aortic outflow
tract
were 15.0*2.6 and 4.2*1.4mmHg, mild aortic valve insufficiencies were found in 2, and mean cardiac index was 5.18*0.19L/min/M*.
We conclude that we should continue anatomic correction for the complex congenital heart anomalies with the malposition of the great arteries because myocardial function seems to be well preserved, though we are still on the learning curve.
