Had a bit of a shock this morning. Had my annual heart check, and was told I will have to have open heart surgery - but not yet! If I didn't have ms, then he'd be doing it now, (meaning probably in about 6m) but as I do, he'll do it in about 2 years; something to do with having a look at arteries while he's in there rather than opening me up twice, and memory problems sometimes caused by heart/lung machine?
As you can tell, I am now not 100% sure of what he said, and clearly didn't ask enough questions.
I mainly remember thinking something about 5% being good odds, so I may have misunderstood something really badly as that doesn't sound like good odds to me now 
I am actually quite sanguine about it, so I would be really grateful if any cardio people could explain stuff to me (I know it's a big ask).
Thank you.
