Fifteen patients have undergone total correction of transposition of the great arteries (TGA) in the past two years. Four were under 6 months of age and weighed 3.4, 3.5, 4.3, and 5.7 kg., respectively; 6 were from 13 to 21 months old; and 5 were 2 to 10 years old. In this series, balloon atrio-septostomy (BAS) provided palliation that was brief and often unsatisfactory. All 8 patients who had BAS without surgical septectomy had severe cyanosis, exercise intolerance, and retardation of growth and development prior to correction. There were 2 operative deaths related to complicated TGA and 1 unrelated late death. All survivors have improved dramatically. Survival alone is therefore no longer considered to be successful palliation following BAS. If adequate relief of cyanosis and reasonable growth and development are not achieved, total correction in infancy is a favorable alternative to surgical septectomy.
