Is atrial septal defect same as patent foramen ovale?

A patent foramen ovale, or PFO, is a special type of hole between the upper chambers of the heart. While an Atrial Septal Defect is always considered a structural abnormality in the heart, everyone at birth has a PFO.

Is a PFO a heart defect?

One of the most common congenital heart defects is an atrial septal defect (ASD), including patent foramen ovale (PFO). Some CHD can often cause congestive heart failure or heart disease as the defect makes a heart work harder than it should.

How can you tell the difference between a VSD and ASD?

An atrial septal defect (ASD) is a hole in the wall between the heart’s two upper chambers. ASD is a congenital condition, which means it is present at birth. A ventricular septal defect (VSD) is a hole in the wall between the two lower chambers. In children, a VSD is usually congenital.

What is patent foramen ovale?

A patent foramen ovale (PFO) is a small opening between the two upper chambers of the heart, the right and the left atrium. Normally, a thin membranous wall made up of two connecting flaps separates these chambers. No blood can flow between them.

What happens if foramen ovale does not close?

Rarely, a patent foramen ovale can cause a significant amount of blood to bypass the lungs, causing low blood oxygen levels (hypoxemia). Stroke. Sometimes small blood clots in veins may travel to the heart.

What does patent foramen ovale mean?

What is patent foramen ovale diagnosis?

How is patent foramen ovale diagnosed? Specialized testing is needed to detect a PFO. This includes: Echocardiogram (echo) – An ultrasound of the heart to check blood flow across the heart valves and chambers. Transesophageal echo (TEE) – A probe with a tiny camera is placed in the esophagus (swallowing/ food tube) .

Does VSD require surgery?

Children and adults who have a medium or large ventricular septal defect or one that’s causing significant symptoms may need surgery to close the defect. Some smaller ventricular septal defects are closed surgically to prevent complications related to their locations, such as damage to heart valves.

What size VSD requires surgery in adults?

Large (6-10 mm in diameter): These VSDs often require surgery (the timing of the surgery can vary slightly). Repair of a large VSD before age 2 can prevent damage to the heart and lungs. Without repair before age 2, the damage becomes permanent and gets worse over time.

Can patent foramen ovale cause shortness of breath?

Unless there are other defects, there are no complications from a PFO in most cases. Some people may have a condition shortness of breath and low arterial blood oxygen levels when sitting or standing. This is called platypnea-orthodeoxia.
