Angiographic Differentiation Between Tetralogy of Fallot and Double-Outlet Right Ventricle Relationship of the Mitral and Aortic Valves
The anatomic hallmark of a double-outlet right ventricle is the separation of the mitral and aortic valves by a band of myocardium. The two valves remain in contact with each other in tetralogy of Fallot no matter how far anteriorly the aorta is displaced. The mitral-aortic relationship can usually be well demonstrated in both anomalies by selective right ventricular angiocardiography.
