The diagnostic diagram shows the right side (RCA) initially with a 50% narrowing but then a short way on is completely blocked 100% all the way round one side, cutting off any supply to the various spurs ("Inf septal(1) and (2)", and "Marg (2) and (3)".
Three other narrowings of 60%, 70% and 30% to various vessels on the other (LAD) side.
The 30% doesn't yet need treatment, both the 60% and 70% narrowings could easily be stented.
The complete blockage runs around what looks like just over half the surface of one side ( or one quarter of the whole circumference) and is problematic. It may be possible to stent but the docs can't be sure.
I'm feeling considerably mentally stronger about this just from bleating on here and listening to others experiences and, the more I look at this in a clear light, the more obvious it seems that I'm going to need a bypass.
Sorry if you've read all this and thought "what the hell??", it's just part of my way of processing. I need to lay it all out and stand back to "see" it.
Time to strap my balls back on and get on with it!
Thanks to all of you, and keep the anecdotes coming! They're more helpful than you can know!
