[Has prenatal diagnosis of transposition of great vessels changed its prognosis?].
Neonatal anatomical correction of transposition of the great arteries (TGA) has transformed the prognosis of this condition but the diagnosis must be made rapidly. The aim of this retrospective study was to evaluate the benefits of antenatal diagnosis on the outcome of TGA. The cases of 50 consecutive neonates with TGA with or without ventricular septal defect hospitalised between 1989 and 1996 were reviewed. All these children underwent anatomical correction of their malformation in the neonatal period. In seventeen of the children the diagnosis was made in the antenatal period at a gestational age of 28.7 +/- 5 weeks of amenorrhea and the other 33 had a postnatal diagnosis at 6.2 +/- 13 days. The clinical and echographic features were identical in the two groups. The risk factors of mortality for the whole population were a Yacoub type B or C coronary disposition, an intramural coronary course, difficulties in reimplantation of the coronary arteries and/or peroperative haemodynamic failure. In the authors' experience, the time of diagnosis (antenatal or postnatal) did not had on the management and prognosis of TGA. Studies with larger population groups are probably necessary to demonstrate the possible benefits of antenatal diagnosis.
