The Structural Heart Program at Georgia Heart Institute provides cutting-edge care to treat the full spectrum of structural heart diseases like PFO. We offer local diagnoses and effective treatment options for congenital heart defects.Treatment includes a catheter procedure or surgery to close the opening in the heart. Minimally-invasive procedures are available to repair heart tissue as an alternative to open heart surgery. The foramen ovale is a hole in the wall between the left and right atria of every human fetus. This hole allows blood to bypass the fetal lungs. Your doctor makes a small cut in your groin. Then the catheter, with tools inside it, is put into your blood vessel and carefully guided to your heart. How is a patent foramen ovale treated? How is a PFO treated?
