title: Tricuspid atresia, hypoplastic right ventricle, intact ventricular septum and congenital absence of the pulmonary valve.
abstract: A case of tricuspid atresia by sealing of the valves, associated with an intact ventricular septum, a hypoplastic right ventricle and the absence of the pulmonary valve, is described. The foramen ovale and the ductus arteriosus were widely patent but there was no interventricular communication. The pulmonary flow was assured by the ductus which had a saccular continuation in the pulmonary trunk. It is postulated that the lesions probably occurred during the period between the XIX and XXII horizons and that the malformed right coronary artery may have played an important role in producing the lesions of the right ventricle.
