Fetal Diagnosis of Tetralogy of Fallot, Major Aortopulmonary Collateral Arteries, and an "Inverted" Pulmonary Valve Causing a Circular Shunt.
Overview
abstract
• Pulmonary blood supply is the main determinant of physiology in tetralogy of Fallot. • This case exhibits a highly abnormal pulmonary valve and blood flow pattern. • Circular shunting may spare fetal health yet lead to neonatal hypoxemia and shock. • Surgical intervention stabilizes pulmonary blood supply in this unusual physiology. • Comparison is made with known subtypes of tetralogy of Fallot.
