They did another heart catheterization today, and everything is fine!
The doctors say she's just having bad spasms, which is very treatable.
She has to lie (lay? I suck at knowing which one to use) flat for like eight hours to make sure the artery closes/heals properly,
but this means she'll be able to come home tomorrow!
It's a darn good thing, too, because I'm about to beat my head against a wall.
Thanks for praying!
