Abstract
Although total physiological correction of d-transposition of the great arteries (d-TGA) is technically feasible in infants, the optimal age for correction has remained controversial because of concern regarding major life-threatening arrhythmias and the long-term results of the intra-artrial baffle procedure. During a 3 yr period, 54 children aged 4 days-5 yr, including 24 infants aged 3 mo. or younger, underwent the baffle procedure. Thirty-two children had simple transposition and underwent only placement of a pericardial baffle; no deaths occurred in this group. Twenty-two had complex transposition requiring, in addition, closure of a ventricular septal defect (VSD) and/or resection of outflow tract obstruction; there were 4 hospital and 2 late deaths in this group. A single operative approach was used in all patients. Sinus rhythm was present at discharge in 85% of the infants and 76% of the older children. Age, mode of cardiopulmonary support and complexity of the lesion influenced these results.
