Update

Had a little bit of a complication at the hospital. As they were monitoring him after the surgery (but before they woke him up), they saw that his chest was filling up with fluid. It's apparently not uncommon after this type of procedure, but it will often stop on its own and Austin's wasn't stopping. They had to take him back down to surgery and reopen the incision on his chest to find what was bleeding.

It was apparently pretty easy to find when they opened him back up, though - it was bleeding pretty bad. They sutured up the aorta that was bleeding and made sure there wasn't anything additional going on before they closed him up again. He's back in the recovery room now, so we're going to try to get some sleep, too.

Been a long day for all of us.
