Right ventricular outflow tract pseudoaneurysm: two cases.

Abstract Right ventricular pseudoaneurysm is a rare complication following repair of Tetralogy of Fallot. Presented are two patients, both with history of Tetralogy of Fallot, successful repair and pseudoaneurysms discovered on symptomatic follow up. Because surgical intervention is often required, the location and characteristics of the pseudoaneurysm are critical determinants of successful outcomes. Cardiac gated CT provides physicians with an invaluable tool in evaluating pseudoaneurysms.
