Ok had results from my MRI scan they say heart a little enlarged (I will have to come in and see them for the the figures) Mixed news although Mitral valve reguritation now classed as moderate and ejection fraction 67% they say I had a small heart attack around the circumflex artery. Ventricular function now normal and MVR not at a stage where it needs treating as yet. I will have to go on and see Consultant about the heart attack and I wonder why this never showed on tests when I went to A and E and had numerous EKGS?
Cardiac magnetic resonance (CMR) is increasingly utilized for dynamic imaging of the heart. It will provide more accurate and reproducible measurements of cardiac chamber dimensions, volumes, and function compared to echocardiography. It is a lot more expensive than an echo though.
I assume that your cardiologist will use the MRI report to validate/invalidate the results of the earlier echo.
Also, it will enable him to better analyze the cause and find a remedy for your problems.
Hi
I have received my date for the MRI 4th July.
Would they be able to tell if the leaky valve is causing the remodelling and hopefully look to a MV repair after the scan?
What are they specifically checking with the scan?
Yes, trying to get the AF under control could be a good approach.
He is the doctor and knows so much more than we laymen.
But why would he doubt the echo then? Perhaps he only said so for your ease of mind?
MRI's often have a long waiting time. But you can always try. :-)
Please let me know the outcome of your consult?.
All the best,
Ger
Atrial fibrillation can cause dilation of the atrium, which in turn can cause increased leakage of the mitral valve (because the annulus of the valve is dilated too).
AF in itself does not cause the ventricle to enlarge however.
The left ventricle enlarges because of excessive workload. This can be from high blood pressure, a narrowed aortic valve, excessive backflow from a leaky mitral valve and probably more.
Your echo results point in the direction of the leaking mitral valve as the cause. Other abnormalities are not reported.
Whether it leaks from the AF or from other causes I can't say.
If your doctor can get the AF under control, perhaps your left atrium can get back to normal size and your mitral valve leakage will also get less.
Anyway, if your heart is in the process of adapting strongly to the mitral leakage, something needs to be done, especially as you experience symptoms. If you wait too long, the adaption will become irreversible. It may not be a matter of weeks, but in a couple of months it could worsen noticeably.
Of course, if the echo is wrong, all the above is to be discarded, but why should the echo be wrong? An unexperienced examiner or so? Not very likely.
The echo shows and reports heart functions and dimensions. I do not see why AF, although it can cause abnormalities, would invalidate the echo report.
If your doctor thinks the echo is not valid, he should order a repeat echo to rule out that possibility.
With your symptoms, I would try to get the MRI sooner if that is possible.
Hi Andrew,
I too have moderate mitral regurgitation, but without the enlargement of atrium and ventricle.
Normally, if moderate leakage is found, the patient is monitored yearly to see if there is progression of the condition.
If there is, they try to find the optimal timing to do repairs to avoid the heart adapting too much to the new, leaky situation
If the heart can not handle the amount of leakage, it starts to compensate which results in abnormal sizes of left ventricle and atrium. This should preferably be prevented or kept limited as it will eventually end in heart failure.
I am no doctor but it seems to me that you are in this compensation phase.
Your EF (ejection fraction) is still good (normal range is 55-70%), but your left atrium is enlarged from the amount of blood that flows back from the ventricle and your left ventricle is enlarged and stiffened while trying to pump enough blood through your body .
It is a bit premature perhaps to say, but if it is the mitral valve that is causing the trouble, there is a good chance that they can repair it, often with minimal invasive surgery. Once the leakage is reduced, your heart may (at least partially) regain is normal size.
Hope this helps you a little.
God bless,
Ger
