Does tetralogy of fallot have anything to do with the coronary artery?

No.: Tetralogy of fallot includes a ventricular septal defect (a hole between the left and right ventricles), pulmonary stenosis (narrowing of the pulmonary valve), right ventricular hypertrophy (thickening of the wall of the right ventricle), and an overriding aorta (an aorta which arises from the top of the ventricular septal defect instead of from the left ventricle).
