We describe two cases of an unusual variant of double outlet right ventricle with intact ventricular septum diagnosed prenatally and confirmed by foetal autopsy in a case. The first case had mitral valve atresia, slit-like left ventricle, and normally related great arteries. The second case had mitral valve atresia, hypoplastic left ventricle, parallel outflows with an interrupted aortic arch.
