Well, given that I've gone through this with my favorite BIL for his second of his two bypasses and his heart transplant, he's going to have to have a heart cath & a number of other tests prior to the surgery. The one problem is that few of the docs and tech people will be around over the Labor Day weekend, although some are on call. Most likely they'll do the tests, then he'll sit, bored out of his gourd, Saturday through Monday.
More likely scared Sh*tless.
