What is Double Outlet Right Ventricle (DORV) ?

Some of the defects I have described are “simple”, some are a little “complex” – but DORV is something else.

It is a common term that actually describes a wide spectrum of heart disease, ranging from something similar to a Ventricular Septal Defect (VSD), through Tetralogy of Fallot (ToF) to Transposition of the Great Arteries (TGA).
