Abstract

Elective intracardiac repair by the Mustard operation is recommended in patients with transposition of the great arteries and intact ventricular septum in the first year of lite (Fig. 1). In patients with associated ventricular septal defect in the first three months of life, early banding followed by early debanding before the first year of life is recommended. When the left ventricular outflow tract obstruction is discrete at valvular or subvalvular level, Mustard operation, closure of the ventricular septal defect and direct relief of outflow obstruction is acceptable, but in patients with an unfavorable left ventricular outflow tract anatomy, a preliminary shunt followed by a Rastelli operation after the age of four years will probably result in a greater salvage. The utilization of surface induced profound hypothermia and circulatory arrest allows for more precise and rapid surgery and is shown to be a definite advantage in the very young infant.
