Hi, Mary, and welcome to the forum. I'm sorry that your husband is encountering so many difficulties. As far as I know, a heart cath is not part of a transplant evaluation. Your hubby must have had a bad result on an EKG, a stress test, or a scan for them to do a heart cath...which would give them a clearer picture of what is going on. Apparently, they found an 85% blockage in one of his arteries. From what you said in your post, your husband is having problems with clotting, so an invasive procedure to clear the blockage, or a bypass operation, would not be possible right now, nor would a liver transplant.
It may just be your lack of punctuation, but there is no such thing as alcoholic hepatitis C. There is alcoholic hepatitis and alcoholic cirrhosis, and there is hep C, which is caused by a virus. Is your husband still abstaining from alcohol? I hope so, as that is the worst thing for the liver.
I know there are people on here--both patients and caregivers--dealing with high amonia levels. I have chronic active hep C and mild cirrhosis, and am a survivor of liver cancer caused by the hep C.
There are many knowledgeable and supportive people here, so I'm sure you will get an answer to your questions. I also recommend that you read some of the old posts, and the educational posts.
Hang in there!
Mary, I've never undergone a transplant evaluation or had a heart cath, but perhaps someone here can answer your questions about it. I can only say that this is the first time I've heard of a heart cath being part of a transplant evaluation, but I learn something new every day here at the forum.
The cirrhosis may have been caused by alcohol, but there is no such thing as alcohol-induced hep C--of that I'm sure.
