A 1-year-old male was referred to our unit because of double outlet right ventricle ( Fig. 1A) with d-transposition of the great arteries and restrictive ventricular septal defect (VSD), located in subpulmonary position, but effectively committed to both pulmonary and aortic outflows because of absent infundibular septum (see Fig. 1, arrow) . A first stage palliation had already been performed by atrial septectomy and pulmonary arterial banding. Preoperative cardiac magnetic resonance imaging

The tricuspid aortic valve was anterior to the right of the bicuspid pulmonary valve (Fig. 1C) . The echocardiogram (Fig. 1D ) also suspected partial Figure 1.
