title: Double-outlet right ventricle with intact ventricular septum.
abstract: An infant with double-outlet right ventricle (DORV) with intact ventricular septum (VS) is described. Hypoplastic left ventricle and mitral valve atresia were also associated. To the authors' knowledge, this appears to be the first case in which this rare form has been demonstrated with magnetic resonance imaging (MRI). The patient required balloon atrial septostomy (BAS) three times until 4 months of age because of progressive cyanosis. In such a form of DORV, surgical atrial septectomy should be performed instead of repeating BAS because the tendency to functional closure of the restrictive secundum arterial septal defect caused by incompetent foramen ovale seems to be prominent.
