Double-Outlet Technique for Tetralogy of Fallot-Type Disease with an Anomalous Coronary Artery

摘要

To reduce the right ventricular (RV) pressure and the pressure gradient between the RV and the pulmonary artery (PA) in Tetralogy of Fallot (TOF) with small pulmonary annulus, it is inevitable to enlarge the small annulus by incising and patching from RV to PA via PA annulus. If the anomalous coronary artery exists in the RV outflow tract, the procedure can not be done.
