Atrial Septal Aneurysm (Overview)

The atrial septum devides the right atrium (upper heart chamber) from the left. During developement in the womb, there is a large opening in this wall which closes soon after birth. The closure can be floppy or redundent, and may be referred to as aneurysm. This is benign and not the type of aneurysm that needs repair or is at risk to rupture.

I have atrial septal aneurysm-protrusion 6 mm beyond the plane and a base width 10mm.Ecg showed incomplete right bundle branch block.Is this dangeros?

Maybe: Every ASD does not need to be repaired. However this one is moderately large. You are 24 with a long life ahead of you. Echocardiograms and other tests will inform your cardiologist about your best choice forward. Also how healthy and athletic you are will help inform the decision. the RBBB is benign and unimportant in my opinion and compatible with a normal life span ...Read more

Can having an atrial septal aneurysm with a hole in it cause brain aneurysms which I have 3. Also is it safe for me to donate plasma?

Possibly: I cannot answer the plasma question but if you have an atrial septal defect then yes, any infected blood clots or material that gets into your veins could get around your lungs and cause it a brain aneurysm (paradoxical embolization). This should be discussed with your cardiologist to see if an atrial septal occluder device is needed. ...Read more

What to do if someone has atrial septal aneurysm and is 13 weeks pregnant. What are some treatments?

Depends: Atrial septal aneurysm (asm) can be associated with irregular heart beats and occaisionally strokes. This depends on the type of asm you have. This can be treated with a blood thinner like aspirin. However, being pregnant may change your treatment options. You should discuss this with your OB and cardiologist. ...Read more

Is an atrial septal aneurysm always something your born with and if not how do they determine if you were or was causes by something?

No problems caused: Atrial septal aneurysm does not cause any problems. Unlike aortic aneurysms, they do not rupture. They may be associated with atrial septal defects, which may lead to other problems, but by themselves atrial septal aneurysms are not dangerous. ...Read more

Floppy septum: The atrial septum devides the right atrium (upper heart chamber) from the left. During developement in the womb, there is a large opening in this wall which closes soon after birth. The closure can be floppy or redundent, and may be referred to as aneurysm. This is benign and not the type of aneurysm that needs repair or is at risk to rupture. ...Read more

If atrial septal aneurysm's don't cause pain then why do I have pain?

If atrial septal aneurysm's don't cause pain then why do I have pain?

Not a true aneurysm: Atrial septal aneurysms are not "true" aneurysm like those that occur in blood vessels with a risk of rupture. Atrial septal aneurysms are simply an excess of tissue left over when you naturally closed your patent foramen ovale with tissue growing together to seal the atrial septum. There is debate about the significance of an atrial septal aneurysm among experts, but they do not cause pain. ...Read more

I have an atrial septal aneurysm and now i know it has a hole they will do a tee how big does it need to be before they will need to patch it?

I have an atrial septal aneurysm and now i know it has a hole they will do a tee how big does it need to be before they will need to patch it?

Depends on flow: It is not just the size. If the shunting between the two sides results in ratio greater than 1.5 and you have symptoms you need the defect closed. Occasionally people get rhythm problems or thrombus formation due to atrial septal aneurysm and may need surgical treatment. ...Read more

Can atrial septal defects and atrial septal aneurysms get bigger? Can they just now show up after having a baby if so does it mean it's bigger now?

Yes, Yes and maybe: Atrial septal defects and the flow through them can increase over time. Changes in blood volume and pressures can unmask a septal defect, and make it worse. The good news is that after her pregnancy, it is also possible for it to get better over time. I would see your cardiologist about this. ...Read more

Are atrial septal defects or atrial septal aneurysms ever the result of infection?

Are atrial septal defects or atrial septal aneurysms ever the result of infection?

Yes but very rarely: It is possible to have an infection in the heart which weakens the atrial septum (causing an aneurysm) or even creates a complete holes (atrial septal defects). This is a very rare finding though and the illness that caused it is generally quite severe. ASDs and atrial septal aneurysms are very common though and most just occur during fetal (i.e. baby) development . ...Read more

Is an atrial septal aneurysm dangerous or life threatening? Is an Effraction of 50-55% bad? Effraction changed from 65 to 50-55 within a yr. Is it bad

Is an atrial septal aneurysm dangerous or life threatening? Is an Effraction of 50-55% bad? Effraction changed from 65 to 50-55 within a yr. Is it bad

Atrial septal aneury: Ejection fraction 50-55% is normal and the change from 65% to 55% may well be within the variation of the measuring technology. Atrial septal aneurysm is generally not per se dangerous or life threatening though it can cause problems. Read this for more info: http://circ.ahajournals.org/content/91/11/2785.full ...Read more

I have an Asd with left to right shunt and an atrial septal aneurysm. Do these shunts start as right to left then as get worse become left to right?

I have an Asd with left to right shunt and an atrial septal aneurysm. Do these shunts start as right to left then as get worse become left to right?

Usually starts L-->R: At birth the left side has higher pressures than the RT side. Thus flow is mainly L-->R. If the ASD is small it may close on its own but if not tends not to cause a problem. If it is large the flow L-->R increases volume load on the Right leading to increased RT pressure, this will reverse the net flow to Rt-->Lft. If large it should be closed before development of increase RT pressures. ...Read more

Atrial septal aneurysm can they rupture? Are they dangerous.Echo done 4 yrs ago just leakyvalves.Had baby BP went up echo shows small hole & aneursym

Not really: Septal wall dilated, flutters but it is all inside heart so rupture is not the issue. With hole - septal defect, - infection, paradoxical embolism, failure are possibilities. Surgical repair is possible. ...Read more

I have been diagnosed with atrial septal aneurysm and now know there is a PFO after having a bubble study done only a few bubbles seen. Should I worry?

Possibly: You maybe at increased risk of stroke. Patients who develop strokes of unknown cause (cryptogenic) have a high probability of having a pfo/aneurysm. Stroke prevention may include medications such as aspirin plavix (clopidogrel) or warfarin. Consultation with a cardiologist who can visualize your echo films or possibly do a TEE can guide you further. ...Read more

Is an intra atrial septal aneurysm along with an ASD or Pfo dangerous? Can this aneurysm rupture?

No not rutpure, but: Aneurysmal interatrial septum refers to the 1cm billowing of the interatrial septum around a vertical axis. The risk with a PFO or ASD, is that of thromboembolism and potential stroke. Refer to research work by S. Homma from Columbia University, NY who initially suggested a link between cryptogenic stroke and PFO. Consider antiplatet therapy, before closure device, if possible. ...Read more
