Double outlet right ventricle, non-committed ventricular septal defect and pulmonic stenosis. Anatomical and surgical considerations.

A case of double outlet right ventricle with pulmonary stenosis, a non-committed muscular ventricular septal defect occupying the sinus and trabecular portions of the ventricular septum, an additional small subtricuspid ventricular septal defect, situs solitus, atrioventricular concordance and aortic d-position is described. Atrioventricular valvular canal type malformations, splenic, systemic or pulmonary venous anomalies, all frequently seen in double outlet right ventricle with uncommitted VSD, were not present.
