My Father has had 2 metal valves placed in his heart. He called today to tell me he now has kidney failure. Told me there wasn't much they could do because of the valves. He is going into the hospital in June, and the way he is talking he's not coming out. He doesnt want us children to be upset with his wife for pulling the plug. Can somebody let me know if there are any options. He's also a diabetic.
