Complete transposition of the great arteries and coarctation of the aorta.
Thirty-two patients with complete transposition of the great arteries (TGA) and coarctation of the aorta (C of A) were seen at The Hospital for Sick Children, Toronto, Canada, between 1963 and 1983. Three patients had only mild C of A and have not required coarctectomy (Group I); 29 had a severe form of C of A (Group II). Two patients in Group I and 21 in Group II had a ventricular septal defect. Subaortic obstruction was present in 5 patients in Group II. The mechanisms included anterior deviation of the infundibular ventricular septum, anomalous right ventricular muscle bundles, and abnormal ventriculoinfundibular fold. Five patients in Group II had a hypoplastic right ventricle. Coarctectomy was performed in 25 patients, and 5 died (20% mortality rate). Sixteen patients had repair for TGA (13 Mustard, 2 Jatene , 1 Rastelli), and 2 died (12% mortality rate). Life-table analysis shows that only 68% of the patients with TGA and C of A survived the first month of life. The 5-year survival in this group was 57%. In the same period, 94% of patients with uncomplicated TGA survived the first month of life and the 5-year survival rate was 89%.
