We report a case of a 15 month-old boy who underwent the arterial switch operation using cryopreserved aortic homograft for transposition of the great arteries with pulmonary regurgitation, with coexisting right ventricular outflow tract obstruction precluding atrial switch operation. Follow-up echocardiography at 6 months showed trivial neoaortic valve regurgitation, no significant systemic outflow obstruction, with good cardiac function. In small children, the choice of material for left ventricular outflow tract reconstruction is one of the most crucial issues. Cryopreserved homograft has been one of the primary options for the aortic valve replacement in small children because of the ease of suturing and excellent hemostasis.
