Seven infants weighing from 6.4 to 10.3 kg underwent correction of
transposition of the great arteries by the venous transposition operation
as described by Shumacker. In this operation, a new atrial septum is
constructed using a bipedicled right atrial flap, and the lateral atrial
wall is constructed using a viable pericardial flap. Three of the patients
had an associated ventricular septal defect. Six of the seven patients
survived and have had an excellent clinical result. Although atrial
arrhythmias were common in the early postoperative period, all patients are
now in sinus rhythm. Two patients have had postoperative cardiac
catheterization and cineangiography, which showed excellent hemodynamic
results. The modified Shumacker operation preserves two of the three
internodal pathways, provides a compliant, viable atrial septum, and
permits fabrication of a generous-size physiological left atrium. This
appears to offer advantages not present in the Mustard procedure.
