Patent foramen ovale (PFO) closure involves closing a small tunneled hole in the heart that has been linked to an increased risk of stroke. 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. A patent foramen ovale closure is typically recommended for active, younger patients who have had a stroke with no other explanation other than PFO. Our team of interventional cardiologists specializes in a minimally invasive PFO closure procedures. A patent foramen ovale occurs when a hole that is always present in a newborn's heart fails to close as it should once the lungs begin to function after birth. In this heart surgery, the surgeon uses stitches to close the PFO . If the percutaneous approach is unsuccessful, ASD closure can be achieved using surgery. In this heart surgery, the surgeon uses stitches to close the PFO . Complications and adverse events during long-term follow-up are rare.
