Double Outlet of Both Ventricles With an Unusual Relationship of the Great Arteries.

Double outlet both ventricles (DOBV) is a rare form of ventriculo-arterial connection wherein the outlet septum is perpendicular to the crest of the apical muscular ventricular septum, thus committing both arterial roots equally to both ventricles. The anomaly has been described in very few reports, with clinical reports being even rarer. We report perhaps the first case of DOBV in which the relationship of the arterial roots themselves is discordant relative to the ventricular topology.
