Input needed

[Brenda_D]

I got my echo back yesterday. They said it was ok.
When I looked at the report, it said LVEF 55%, according to the report it is supposed to be between 60% - 100%. I'm not sure how an echo compares to a muga. My muga was 56% a year ago. I'm not too worried about the LVEF though.
Here's what concerns me. Left atrium mildy dilated.
Mild mitral regurgitation, mild tricuspid regurgitation.
I'm scheduled for a chemical stress test Thursday and I get my 3 week dose of Herceptin Wed.
Should I have a chemical stresser right after my treatment? Especially with some mild valve problems?

I will ask my onc, but I wanted your input, please.
Thanks.
