I had a chance to talk very briefly with the doctor I believe I will choose for my surgeon. He comes with a great reputation. I didn't have an appointment but he had a minute for me between 2 open heart surgeries scheduled for that day. He will be replacing the Aorta valve, probably with a synthetic valve. He said he does all these replacements "off the machine". I think that means not hooking me up to a machine to for my blood during the surgery. This sounds like it is a good thing, but then I wondered if that is even possible. Any thoughts?
