Repair of tetralogy of Fallot after Waterston anastomosis.
Sixty-three corrective operations have been performed in patients with Tetralogy of Fallot and a previously constructed Waterston shunt. The patients were from 1.4 to 8 years of age (median 4.3 years), and the mean interval between the Waterston shunt and the repair was 39.3 +/- 16.05 months. Three patients developed pulmonary atresia and six required a second anastomosis prior to intracardiac repair. Kinking and stenosis of the right pulmonary artery at the site of the Waterston anastomosis occurred in 12 (19 percent; 70 percent confidence limits 14 to 26 percent) patients who required patch enlargement of the right pulmonary artery at repair. Seven (11 percent; 70 percent confidence limits 7 to 17 percent) patients died in the hospital and three (5 percent; 70 percent confidence limits 2 to 11 percent) during the period of late follow-up. None of the early or late deaths was specifically related to the presence of the previously performed Waterston anastomosis.
