Thank you all for the prayers for my grandmother.
From my medically-savvy Aunt: "They replaced the aortic arch and the descending aorta. " In layman's terms... she's got herself some bionic parts. Perfect, if you ask me. Normal human parts can't stand up to a woman like her. New parts mean she's going to last longer and be stronger and do more with those new parts than a normal person could do with their whole heart.
Continued prayers are certainly welcome - they're watching her blood pressure and praying against any sort of recovery complications such as stroke. My mother's gone up to be with her for an undetermined amount of time - she'll be in the hospital for around a week and she'll need a lot of help when she gets home. Keep sending good thoughts her way.
Ogee is travelling up with my dad in another week or so - he'll be driving up with my sister. It's supposed to be a Christmas gift, but with her being laid up, I think she could use the perk-up. The plan is still for us to go home for Christmas - I fear that Kid being around while she's recovering from open-heart surgery might just be a bit too much, so we'll keep him and his endless supply of energy down here until Christmas.
