Can a dilation of the ascending aorta be temporary and caused by infection?

Can a dilation of the ascending aorta be temporary and caused by infection?

Not Temporary: Chagas disease is a tropical parasitic disease caused by the protozoan Trypanosoma cruzi. It can cause aortic dilation aka aneurysm.

Once dilation happens it is not temporary. Close monitoring needed. ...Read more

Can I safely participate in martial arts with a dilated ascending aorta of 4.2 cm?

Can I safely participate in martial arts with a dilated ascending aorta of 4.2 cm?

Need vascular eval: You need to follow-up with a vascular surgeon and have your BP followed as well as cholesterol, stop smoking if you do, etc. And generally get routine follow-up visits. Increased activity, like those in martial arts, may rise your BP, so it would be a question, that the Vascular Dr. Who knows you best and treats you currently, would be able to tell you including exactly what activities 4U. ...Read more

Loeys Dietz child and my ascending aorta is dilated. Any knowledgable drs. In Atlanta?

Sibley Heart Center: Sibley Heart Center (with Emory University) has an excellent reputation. I'm not from the area and don't know if they have any special center for connective tissue disorders (like Loeys-Dietz, Marfan or Ehlers-Danlos), but that would be a good place to start. Medical treatment and follow-up may be sufficient if the dilatation is not severe. Good luck. ...Read more

Just followed up with cardiologist for dilated ascending aorta found at Mayo. They measured it wrong. Isn't Mayo supposed to be better than that?

Just followed up with cardiologist for dilated ascending aorta found at Mayo. They measured it wrong. Isn't Mayo supposed to be better than that?

No one's perfect: The Mayo clinic has an excellent reputation & would be considered relatively reliable. However, certain msmts can change over time. Also, there will always be some variability between msmts (with less variability by definition for more precise msmts). Looking from a different angle or with better echo windows may also affect the result. Lastly, no one is perfect, so anyone can make a mistake. ...Read more

8 yr old nonverbal autistic child + bicuspid aortic valve + now also diagnosis with 3.15 CM dilated ascending aorta. When to do surgery?

8 yr old nonverbal autistic child + bicuspid aortic valve + now also diagnosis with 3.15 CM dilated ascending aorta. When to do surgery?

Complicated question: Timing of aortic root replacement is complex in childhood. Factors include the z-score of the aortic root diameter (which requires knowledge of body surface area), the rate of growth of the aorta, the function of the aortic valve, and the underlying cause. At 3.15 cm, it is unlikely that surgery is indicated at this time. Surveillance, typically by echocardiogram, should be performed regularly. ...Read more

Follow up? Re diagnosis of mild ectasia (3.8x3.7 cm) on ascending aorta via cardiac ct: have had chest x-rays in past years (2010) with only normal results. Is this something an X-ray could miss?

Yes: The degree of ascending aortic enlargement is small and would no be expected to be picked up on a regular chest x-ray. A ct scan or MRI would be needed to reliably image a mild aortic enlargement of the size you mention.
Follow up would be with repeat ct scan in 6 months and then yearly after that if no dramatic enlargement was seen in first 6 months. You should be on a beta blocker (medication). ...Read more

Is CT cardiac calcium scan accurate in diagnosing mild ectatic ascending aorta? Have fam. History of heart disease (father died at 46 with chf) and slight heart murmur. Should I have other tests done

No: You need an aortic ultrasound to determine if it is too large. A calcium score of the abdominal aorta is useless. A vest x-ray with abdominal view can tell you if you have a mildly ecstatic aorta or not but that is not harmful. If your doc is concerned the best test would be a stress test of your heart. Talk to your doc. ...Read more

What's the newest surgical procedure for an aneurysm of the ascending aorta?

Covered Stent: The latest treatment modality for an ascending aortic aneurysm would be an endograft (covered stent). One of the challenges is maintaining flow to the great vessels of the aortic arch. Branched and fenestrated endografts are currently being developed and tested to accommodate the aortic arch and the ascending thoracic aorta. ...Read more

What is the latest surgical procedure for an aneurysm of your ascending aorta?

Stent grafts: Special stent graft techniques are being researched to allow for preservation of the aortic arch branches and avoid a more invasive chest incision. Treatment of ascending aorta aneurysms involving the coronary arteries still will require bypass surgery, although may be combined with stent graft techniques. ...Read more

Ascending aorta diameter 2.8cm? Is that normal for 18 year old? Female

Could be.: The average AAOD (asc aorta diameter) by CT scan is about 3 +/- 0.4 cm (i.e., there is variation among people due to genetic factors, body size, & undefined parameters). So 95% of humans have aortic root diameters between 2.6 cm & 3.4 cm. You're certainly in that range. Unless you have symptoms, I would not worry about these detailed results. TTYD who ordered test.

When measuring ascending aorta size (4.5 to 5.0cm above valve)by echo which measurement is more accurate:outer wall to outer wall or inner wall to iner?

When measuring ascending aorta size (4.5 to 5.0cm above valve)by echo which measurement is more accurate:outer wall to outer wall or inner wall to iner?

The accuracy of the: Measurement is not appreciably affected by using the inner vs the outer wall. The accuracy will be the same. The question is which measure is a better predictor of root diameter with regard to clinical outcome. The answer is actually to measure from the leading edge to the leading edge of the root above the valve. In other words, the outer edge of the first seen root to the inner edge of the last ...Read more

For a male age 50, 6-1, 162 pounds, is an ascending aorta diameter of 3.8 in the normal range?

For a male age 50, 6-1, 162 pounds, is an ascending aorta diameter of 3.8 in the normal range?

By echocardiogram?: The 'normal range' of aortic root diameters varies based on (1) the modality used (most commonly used is ultrasound / echocardiogram) and (2) your height. The usual upper estimate is 2.1 cm/m of height. For someone who is 73 in tall (such as yourself), that translates to an upper limit of 3.8 cm, which is exactly what is measured in your case. Anything above that could be considered dilation. TTYD ...Read more

female 58 yrs Small aneurism in ascending aorta and arch; also PFO; high LDL & chol- can't take statins. Willl diet & exercise be enough?

Depends on LDL level: AHA/ACC guidelines =treat based on an assessment of lifetime risk of developing heart disease. Typically, before statins are started, a sincere attempt at lifestyle changes, including avoiding saturated fats& exercising (atleast walking even 10, 000 steps/day) ought to be undertaken. Recheck fasting lipids 6 months later. No egg yolks, no shellfish; eat salmon, almond/walnut (Incr. HDL) ...Read more

What does this mean: ascending aorta at the level of the pulmonary artery bifurcation measures 2.5 x 2.3cm ap and transverse? Is this too big?

Not too big.: When is the ascending aorta too big? Depends on the aortic valve, how fast it is growing, underlying connective tissue disorder, symptoms, size of the patient, and, of corse, size of the aorta. Two and a half centimeters is not too big though. ...Read more
