How serious is a hole in your heart? The hole increases the amount of blood that flows through the lungs and over time, it may cause damage to the blood vessels in the lungs. Damage to the blood vessels in the lungs may cause problems in adulthood, such as high blood pressure in the lungs and heart failure.
What is PFO stroke? If a PFO exists, a little blood can flow between the atria through the flaps. This flow is not normal. The condition is most important because it raises the risk for stroke. Blood clots can travel from the right atrium to the left atrium and out to blood vessels of the body.
Can you survive with a hole in your heart? It is very possible to live with a hole in your heart, without ever realising that it’s there. A patent foramen ovale, also known as a PFO, is a hole between the left and right atria (upper chambers) of the heart that we all have when we are in the womb, but this should close shortly after we’re born.
How does a PFO cause a stroke? Stroke. Sometimes small blood clots in veins may travel to the heart. They may go through a patent foramen ovale and into the left side of the heart, where they can travel to the brain and block blood flow, causing an ischemic stroke.
