[Surgical alternatives in the treatment of double-outlet right ventricle].

Double-outlet right ventricle (DORV) is a type of ventriculo-arterial connection, in which both great arteries are connected to the morphologically right ventricle in at least 50% of their diameter. The relation of the great arteries with the ventricular septal defect (VSD) and the pulmonary stenosis, are important anatomical aspects in the election of the surgical technique. In this study we describe four patients with DORV, in whom different surgical techniques were used according to the specific anatomy of each case. Two patients had subaortic restrictive VSD, with subpulmonary stenosis in one of them. In the other two patients the VSD was subpulmonary with the aorta anterior and to the left, in one of these existed moreover a severe mixed pulmonary stenosis. It is concluded, that with different surgical techniques according to the specific anatomy of each patient, good results can be obtained in the surgical treatment of these complex congenital malformations.
