[Anatomic repair of transposition of the great areries or arterial switch operation]

ABSTRACT

Between January 1990 and September 2003, 62 patients underwent anatomic repair of a transposition of the great arteries. Mean operative age is 40 days. Transposition of the great arteries was simple in 38 cases and associated to a large ventricular septal defect in 24 cases. 44 patients have had an atrial septostomy of Rashkind and 45 an infusion of prostaglandin E 1.5 patients with simple transposition of the great arteries have had left ventricular retraining before arteriel switch. In association to arterial switch, were performed closure of ventricular septa] defect in 24 cases, cure of coarctation of the aorta in 4 cases and cure of an abnormal partial pulmonary venous return in 1 case. Early mortality was 6,45 %. After a mean follow up of 3 years, one patient died suddenly [late mortality is 1,72 %] and one patient had to have 2 reoperations. Results of anatomic repair are now excellent. Late mortality is essentially related to coronary complications so that a careful follow-up is mandatory
