A six year old boy was catheterized preoperatively and tetralogy of Fallot with anomalous coronary artery was diagnosed. During operation, he was found to have double outlet right ventricle with subaortic VSD, pulmonary stenosis and the anterior descending coronary artery originating from the right coronary artery. The left outflow tract was made by suturing a internal conduit from VSD to the aorta. The anomalous coronary artery was made free from the surrounding tissue and mobilized to enable a pericardial patch sutured by lifting the artery to relieve the pulmonary stenosis. In young children, the proposed method is preferable compared with other methods employing some types of grafting with a valved conduct or AC bypass procedures.
