Double Outlet Ventricles

Double outlet ventricle is present when all of one great vessel and more than 50% of the second great vessel arise from one ventricle.

Total correction is undertaken at any age when symptoms dictate. Surgery is performed with cardiopulmonary bypass, moderate hypothermia, aortic cross-clamping, and cardioplegia with local cardiac cooling.
