He is feeling much better as a result, and is now eating and drinking on his own in small quantities. He had an echo-cardiogram and an ECG today, and these both showed that everything is repaired.
They have indicated that he will probably be discharged tomorrow, which is a little scary for us as he still requires quite a bit of care that we don't really know how to provide. And we are staying in a hotel room to boot. We have to stay here for a follow up appointment in 1 week, so at least we will be close to the hospital.
