What is different between PFO and ostium secundum atrial septal defect?

Size & Location. A pfo is the persistence of a normal fetal communication between the top two chambers of the heart. A secundum ASD is an abnormal hole in the atrial septum. They vary in size though, so treatments vary.
ASD Vs PFO . ASD is a defect ( hole) in the atrial septum and usually requires closure. Pfo ( patent foramen ovale ) is a potential opening between two flaps of atrial septum which usually does not produce shunt. If atrium enlarges, pfo can open up. Recently pfo has been implicated in stroke and migraine.
Size. Location is essentially same. Patent foramen ovale- pfo is small and a flap may intermittently cover, asd secundum is at foramen ovale and always open and variable in size. Asd primum is higher, may be larger and include superior pulmonary vein anomaly.

Does atrial septal defect differ from pfo? How does it differ? My cardiologist suspected that I have asd/pfo. I think he's not sure.

Pfo vs Asd. Pfos are very common in the general population in fact as high as 30 per cent in your age group . An ASD is a somewhat different entity where there is a larger communication between the 2 upper chambers of the heart . Pfo generally require no treatment ASD s at times need repair or closure depending on the size. Read more...
Asd is a real hole. Whereaa a pfo is a normal valve that fuses and closes the septum in more than 80% after birth (it needs to be open in fetal life) an ASD is a true defect with lacking tissue leading to a communication between both filling chambers of the heart. If >6mm it likely causes volume load for the right heart and sjould be closed either by surgery or cath. Read more...
Similar but not same. Both are connections between the atria. A pfo is persistence of a connection that is normally present while in the womb. A true ASD is a hole in the septum. 25% of people have a pfo. And many people have true asds. The decision to repair them (can be surgery or in cath lab) depends on numerous factors that i would recommend you discuss with your cardiologist. Read more...

Can endocarditis CAUSE atrial septal aneurysm with a pfo or ASD shunt?

Endocarditis is an. infection of the heart. Atrial septal aneurysm, patent foramen and atrial septal defects are anatomical variants determined by your genetic makeup and embryological development. There is no causal relationship between the two. Read more...
No. A cerebral embolism can happen in someone with an undiagnosed PFO or ASD +/- atrial septal aneurysm. Endocarditis causes valve degeneration and/ or there could be a coronary embolism causing a heart attacks. . Read more...

Is it a problem to drink alcohol if I have a secundum atrial septal defect?

Yes. Drinking in moderation (you must know your limits, do not drive etc) is perfectly fine with an asd. Stay responsible and safe, but an ASD itself--without other congenital defects or heart rhythm problems--is not a contraindication to drinking alcohol. Read more...

What is a secundum atrial septal defect?

ASD, A hole... A secundum atrial septal defect (ASD) is a hole between the upper two chambers of the heart. Small hole are followed, monitored to determine if the heart is becoming dilated due to the extra work. Most secundum asds can be closed in the pediatric or adult cath lab using a amplatzer or gore septal occluder. Open heart surgery is required in a small percentage of patients. Read more...
A communication. A communication between the right and left atrium is called a atrial septal defect. Its a congential defect. The secundum type is in the middle of the septum and easily fixed with surgery or catheters. Read more...
ASD. An atrial septal defect is a common congenital geart defect. It is a hole in the atrial septum - the wall between the left and right atrium. This lets blood flow from the left into right atrium (usually). If not caught at an early age, it results in excessive blood to right side of heart and lungs. Fixed with surgery (sutyred closed) or with a umbrella like device via cath. Read more...

Hole between atria. A secundum atrial septal defect is the most common of the 4 types of atrial septal defects. This occurs when a hole develops in the tissue separating the l and r collecting chambers of the heart. Some small and moderate sized secundum asds will close in time in children, but larger ones, and ones that persist to adulthood, often require surgical or catheter-based closure. Read more...

What is the different between a PFO and ostium secundum?

Subtle. You're right that both can cause r to l shunt (and rarely l to r). But everyone is born with a foramen ovale (which is small) and when it fails to close, there is usually a flap and shunting only occurs with increased right atrial pressure (like during straining or cough). A secondum ASD is a fixed pathological defect in the interatrial septum. Size is variable. They're similar but different. Read more...
PFO vs ASD. Patent foramen ovale is communication between the right / left atria. It is common and a result of a failure for this communication to close when we are born. As a fetus this is needed because the babys lungs are not ready to oxygenate it bypasses the immature lungs of the baby and goes into moms circulation for oxygenating. It should close as babys lungs mature and take over. ASD is pathalogic. Read more...
Size. It's really just the size that distinguishes these. A pfo is small and rarely causes any problem. An ASD is larger and would only cause a problem if it is large enough to do so. Read more...
