FAQ
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.
If treated, someone with atrial septal defect can expect a normal life expectancy. However, if left untreated, evidence suggests your life expectancy could be shortened due to a higher risk of heart failure or stroke.
ASD is a development issue, leaving a lasting hole. PFO is an opening that does not seal after you are born. Even though many adults have PFO, they often do not know it. A PFO is smaller than an ASD, which can be bigger and cause more issues.
It is possible to differentiate an ostium secundum ASD from a PFO on CT images. Ostium secundum ASDs are a direct communication between the two atria, whereas a PFO defect is a tunnel of variable width and length between the two atria 5. The PFO flow is usually left to right but can be bidirectional.
Conclusions: Atrial septal defects and PFOs can be differentiated using the characteristic direction of the contrast jet from the left to right atrium and the appearance of the atrial septum on coronary CT angiography.
Small holes between the upper chambers of the heart may be categorized as an atrial septal defect (ASD) or patent foramen ovale (PFO). An ASD is a congenital heart defect, a condition that you are born with. PFOs can occur only after birth when the foramen ovale fails to close.
Over 40 adults with ASD might face rhythm troubles, like atrial fibrillation, which could lead to stroke or lung pressure problems. PFO is usually less of a worry but can still cause strokes or mini-strokes when clots travel through to the brain.
CT diagnosis of PFO was defined as (1) a channel-like appearance of the interatrial septum (IAS) and (2) a contrast agent jet flow from the left atrium (LA) to the right atrium (RA). ASD was defined as (1) the IAS resembling a membrane with a hole and (2) a contrast jet flow between the two atria.
PFO was found in 25 to 30 percent of individuals in an autopsy study and in a community-based transesophageal echocardiography (TEE) study 4,5.
The “defect” from a patent ductus arteriosus (PDA), similar to the patent foramen ovale (PFO), is a persistent communication between the two large vessels originating from the heart (the aorta and the pulmonary artery) that usually closes soon after birth.
More info
ASD is a birth defect with a gap in the heart's upper wall. This gap happens when the wall does not form right before birth.There are two types of holes which can be present between the upper chambers of the heart: an Atrial septal defect (ASD) and a patent foramen ovale (PFO). Generally an ASD hole is larger than a PFO. The larger the hole, the more likely symptoms are.
