[Anatomic correction of the congenitally corrected transposition of the great vessels by the first successful "double switch" operation in Hungary].
Congenitally corrected transposition of the great arteries is a rare defect characterized by discordant atrioventricular and ventriculoarterial connections. Symptoms result from one or a combination of associated cardiovascular malformations, including ventricular septal defect, pulmonary stenosis or atresia, tricuspid valve dysfunction, dextrocardia, hypoplastic left or right ventricle. Correcting exclusively the associated defects, leaving the morphologic right ventricle in systemic position, will determine the patient's life-long prognosis. Anatomic repair by double switch technique may improve survival of patients with congenitally corrected transposition of the great arteries by establishing the morphologic left ventricle in the systemic circulation. A 3-year-old girl with congenitally corrected transposition of the great arteries, ventricular septal defect, hypoplastic right ventricle, and previous palliative procedure was corrected by double switch technique and patch closure of ventricular septal defect. The authors prefer the double switch procedure inspite of its many surgical challenges because it has very good long-term outcome. The more simple surgery namely the operation of only associated cardiac defects will involve the possibility of deterioration of right ventricular function.
