This may happen with some forms of congenital heart disease like Tetralogy of Fallot or with a late ASD. This technique can quantify right to left shunts. Patient Prep: No patient preparation. WebA PFO and Atrial Septal Defects (ASD) are often referred to as a “hole in the heart.” The PFO’s flap-like valve enables shunting — the abnormal mixture of blood between the right and left sides of the heart. If the PFO allows right to-left shunting, oxygen-deprived blood can carry harmful substances to the brain.
