Double Outlet Right Ventricle, Non-committed Ventricular Septal Defect and Pulmonic Stenosis. Anatomical and Surgical Considerations

Summary

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.

At operation an internal tunnel connecting the left ventricle to the aorta was created, and a Hancock valved conduit between the right ventricle and the pulmonary artery was employed.
