Arterial switch operation is preferable in the presence of resectable subpulmonic stenosis in patients with transposition of the great arteries. We present two patients, aged 6 and 4 years, respectively, who developed acute aortic insufficiency and pulmonary edema early after arterial switch operation with subpulmonic resection. Neoaortic valve replacement with posterior annular enlargement was performed in the early postoperative period. The patients were in NYHA functional class I and II after postoperative 24 and 16 months, respectively. Possible causes of acute aortic insufficiency following arterial switch operation and treatment alternatives are discussed.
