Cor triventriculare: infundibular stenosis with subdivision of the right vertricle

ABSTRACT

Two unusual cases of triventricular hearts are described in which the right ventricle is partitioned into two chambers, the smaller of which is placed antero-superiorly and gives off the pulmonary trunk. Other anomalies present are high interventricular septal defect, overiding aorta and biscuspid pulmonary valves. Only a few cases of this anomaly appear to have been described. The possible pathogenesis is discussed and its relationship to Fallot's tetralogy is considered.(AU)
