Thrombus in appendage
son01 posted:
My mom has a thrombus in her appendage extending to the body. The ejection fraction was 30% on 12.02.2013 and was 42% on 22.02.2013. She is on warfarin 5 mg and her INR is around 2.35. Should I do something else o cure her quickly. How much time will it take for the thrombus to dissolve completely....???

"How much time will it take for the thrombus to dissolve completely."

This is a variable, as the body breaks the thrombus (blood clot) down in time, which can span from weeks to months. Warfarin (brand name Coumadin) only prevents the thrombus from becoming larger and new ones from forming.

"The ejection fraction was 30% on 12.02.2013 and was 42% on 22.02.2013".

As reported, left ventricular ejection fraction (LVEF) can vary throughout the day, and can vary from one type of diagnostic imaging test/modality to another, such as non-invasive echocardiogram, **MUGA scan/ERNA (reported as being the most accurate of the non-invasive methods, yields reproducible results), gated-SPECT scan with Cardiolite or Myoview (common nuclear stress test), Cardiac PET, Cardiac MR/MRI, and invasive X-ray angiography (heart catheterization).

**To get a decent estimate of LVEF, a MUGA scan is reported as being the most accurate of the non-invasive methods.

Pertinent excerpt from an About. com article - Richard N. Fogoros, M.D.

When is the MUGA scan more useful than other heart tests?

The advantages of the MUGA scan over other techniques (such as the echocardiogram) for measuring the LVEF are twofold
. First, the MUGA ejection fraction is highly accurate, probably more accurate than that obtained by any other technique. Second, The MUGA ejection fraction is highly reproducible. That is, if the LVEF measurement is repeated several times, nearly the same answer is always obtained. (With other tests, variations in the measured LVEF are much greater.)

Best of luck to your mom down the road of life.

Take care,

It often dissolves after a month of warfarin treatment. Her doctor may recommend a repeat transesophageal echocardiogram to take a look.
