Abstract

This is a report of a successful, rapid two-stage arterial switch operation in an infant with dextrotransposition of great arteries with an intact ventricular septum beyond the appropriate time for arterial switch operation. A 4-month-old female infant was admitted due to severe cyanosis, respiratory insufficiency, and frequent diarrhea secondary to ischemic colitis. Echocardiographic examination presented marked leftward deviation of the interventricular septum, and left and right ventricular pressures as measured by cardiac catheterization were 40/4 mm Hg and 85/2 mm Hg, respectively. Fifteen days after a preparatory operation (pulmonary artery band with modified right Blalock-Taussig shunt), left ventricular-right ventricular systolic pressure ratio increased to 105/90. Arterial switch operation associated with the division of the right Blalock-Taussig shunt and the removal of pulmonary artery band was performed. After the operation, the infant showed normal cardiac function with no postoperative complication.
