RAG, welcome to the best site around. Had Hodgkin's (mantle treatment) in 1970... We were watching for trouble for years (I also have full blown ankylosing spondylitis) and we darned near missed...in 2004, the obvious...rad LOVES the ostium of RCA's, mine was 91-93% blocked with a material called "apatite", a kind of rock, similar to teeth. Nuclear adenosine scan, one stent, and good to go!!! Whole new life back. Then the malformed aortic valve, we could've all sworn we saw a ring of pearl-like calcium surrounding what was left of the valve...wrong again!! No calcium anywhere...!!! Also-and this will more closely (or not!) apply to you..no scarring, fibrotic or otherwise when he went in. Now it's very possible the tissue LOOKS great, but may be "older" than it appears...my tricuspid took a lot of the backed up system pressure, and we'll see if time gives the tissue (along with very good nutrition) a bit more-well, "liveliness". So this is a bit of peek at what I might have done sooner..... Do watch yourself, rad is darned sneaky and just stay darned well on top of things.
So glad you found us, hope we can aid you as much you (will be!) giving us with your reports! It's a terrific place. Welcome! Michellemar
