The very idea of a hole in the heart may sound alarming, but it’s surprisingly common. On top of that, some people may have a hole in their heart and not even realize it.
In fact, the American Heart Association estimates that about a quarter of the American population has some type of hole in the heart. That’s around 82 million people!
If someone has a hole in their heart, it falls into one of two most common categories: patent foramen ovale (PFO) or an atrial septal defect (ASD).
While these holes may be present, they’re often left undiagnosed because they don’t typically cause any issues or symptoms. But that isn’t always the case. Larger holes in the heart can increase your risk of serious health issues and may require treatment.
What is Patent Foramen Ovale (PFO) and how is it treated?
This type of hole in the heart is something that occurs in infancy. As a baby in utero, there is a hole in the heart tissue that separates the left and right chambers, also known as the interatrial septum. This hole is called a foramen ovale and it exists to allow blood to bypass the fetal lungs since they don’t work until exposed to air. However, once born, this hole naturally closes at birth and if it doesn’t, the hole that continues to exist is known as a PFO.
This type of hole is often small in size, and, in most cases, the only effect of a PFO is blood leaking between the right and left chambers. Unless a PFO is detected during childhood, it may go undetected for years, until a person experiences conditions like migraine or stroke that require careful investigation and diagnosis.
Most PFOs require minimal treatment or none at all, they may be left open. In some cases, treatment may be recommended using structural heart intervention, where a closure device is deployed using minimally-invasive techniques.
What is Atrial Septal Defect (ASD) and how is it treated?
An atrial septal defect (ASD) is a hole in the wall (septum) between the heart’s two upper chambers. Unlike a patent foramen ovale (PFO), which is a small hole that simply doesn’t close after birth, an ASD is a congenital defect, meaning the septum didn’t form properly before birth.
Small ASDs may not cause any symptoms and can go unnoticed for years. However, larger holes can lead to symptoms such as fatigue, shortness of breath, frequent respiratory infections or a heart murmur. Over time, an untreated large ASD can place extra strain on the heart and lungs, increasing the risk of complications.
When treatment is needed, the goal is to close the hole and restore normal blood flow through the heart. At Georgia Heart Institute this is may be done through a non-surgical, catheter-based procedure, robotic heart surgery or open heart surgery. Whenever possible, we will choose a minimally invasive approach for the repair, resulting in less pain, shorter hospital stays and faster recovery compared to traditional open-heart surgery. Georgia Heart Institute, in partnership with the cardiovascular surgeons of Northeast Georgia Physicians Group, is a regional leader in robotic heart surgery and offers several advanced procedures.
