Point of reference
A little more details ...
(I did some online research, which didn't tell me much, but)
What my Cardiologist told me (and the Surgeon confirmed) was:
I was born with a heart malformation, whereby the Right Coronary Artery, doesn't follow the "normal" path. In travels between the heart and aorta, therefore when the heart "pumps", it temporarily squeezes off the RCA, yes, that means, it temporarily cuts off blood flow.
What the Surgeon said, was as he looked at the results of the Heart Cath. and Heart CT, was he didn't see any "schema" or anything indicating a significant blood flow problem.
Remember, he was told I have MS, and an MS Hug.
So, during his physical exam of me, he pressed on my chest, rib-cage, etc.
[Note: I fell off my back porch, back in 2009, one of the results was a severe chest contusion]
Yes, the pressure hurt, my chest has hurt since the fall, duh.
Since he believed, that he "duplicated" the results, by pressing on my chest, etc. He believes it's not a heart issue, but a chest wall issue. Hence, the intercostal spasms, "theory".
Well, I go to see my PCP, in 2 weeks, and back to see my Cardiologist in 4 weeks.
When I see my PCP, what I'm going to ask him, is this:
If you tell me, your arm hurts, and I pinch your arm, hard, does the pinching of your arm, hurt?
Did I duplicate the pain in your arm, you already had, no!
What it boils down to is this, as far as the Surgeon, since he didn't see any significant blood flow stoppage, on the Heart CT, then it's not worth the risk of cutting me open to re-route my RCA.
Whether this is the cause of my chest pressure, and my heart feeling "tired", especially after exertion, like walking, mowing, or exercising (riding my exercise bike), we have no idea.
