Fetal tetralogy of Fallot, the ultrasound manifestations of which include aortic overriding, ventricular septal defect, pulmonary stenosis, and right ventricular enlargement. Poor prognostic factors for tetralogy of Fallot include: First, ductal retrograde flow, or significant collateral formation.
