Quick update - she did good, the dr. said it's been a very long time since he's seen anything so bad, but she came through like a trooper. She had the whole pre-op area cracking up the morning of...as usual.
Back when we first met the dr., he mentioned the tissue band that goes around the valve and keeps the heart together. He said it looked calcified as well, but he'd do his best. If it was too bad, she would die, right there. Well, it was bad, and disintegrated while he cleaned it - but he, miracle worker that he is, was able to create a new one from a bovine pericardium. God put her in the right hands, then guided those hands all the way, and the doc admits it.
It took her a long time to get off the ventilator, but they finally got it. Right now, she's either sleeping [pain meds] or in a lot of pain, so continued prayers would be most welcome. I'm going to try to get there every morning around 5:30am, as it's the only way to get a parking spot. That hospital is huge! I think I've walked 20 miles since yesterday morning, and I can't walk well. A nice bonus is that the gal at the coffee shop recognized me this morning, and gave me a punch card for free coffee.
The first verse I saw this morning.....
My flesh and my heart faileth: but God is the strength of my heart and my portion forever. Psalm 73:26. God is good. All the time.
EDIT: Almost forgot. My aunt texted me a pic of her kitty, Snickers - she was praying too.
