Bottom line, nothing to worry about too much right now. (Thought I would get that out of the way first.)
Ok, back to the beginning:
Met with the pregnancy heart specialist today. Dr. S. Apparently, thanks to the radiation treatment from the bone marrow transplant, my heart has some mild aortic stenosis and regurgitation. The key being that it is mild. More simply, my aortic valve is thickened slightly (stenosis) so it doesn’t close completely which causes some blood to leak back into my heart (regurgitation) in the wrong direction. Sounds scary. But she assures me that for now it is at the mild level, so is nothing to be alarmed about at this time. That and I feel absolutely fine. Have no symptoms of heart issues and can train for a 10k make me feel that this is probably not something to concern myself with right now.
She says the risk of any serious complications during a pregnancy (to do with the heart) are in the 2-3% range for me. I have to let her know as soon as I am pregnant, and she will monitor me as soon as we are pregnant and will keep an eye on things as any pregnancy progresses just in case and so we can treat any issues before they become worse, if at all.
From a long term perspective it is something that I should monitor and get regular ECGs every few years just to make sure it is not getting worse. But for now there is nothing else that can be done.
So filing this away in the ‘good to know, random things that are wrong with me thanks to the bone marrow transplant’ file in my brain, and will hopefully not have to revisit this issue for at least another 5 years when I will go for my next ECG.
