Welcome to this fantastic site. You certainly have had your share of terrible problems with your husband's situation. My husband is the patient here and has had a few of these problems, but not all at once. He's had Class 4 CHF, he's had to have his lung drained, he has had C Diff, which is severe ulcerative diarrhea type infection, and he's had an AVR. He missed the IV line infection, and the possible defibrillator, but he's got a pacemaker. He's also had 2 mitral valve surgeries (one to repair a leak), 2 lung surgeries, a serious bout of serum sickness, and a scary temp of 106.7 (both of those gave him a 10 day stay in the hospital, most in the ICU).
Last May he went in for gallbladder surgery and had a disastrous bleedout and almost lost his life. He needed 33 units of blood products to stop the bleed. It took him all summer to recover from that. Right now, he's in the hospital getting treatment for pulmonary hypertension, Class 4 CHF, and anemia. He's been there for 27 days now, but will be home soon, when his INR comes up to snuff. He's feeling a lot better, and lost 24 pounds of fluid. He'll probably be a ton of new medication when he comes home.
I'm telling you all of this to let you know that in spite of how serious things look now, there is every hope that your husband will recover and the human body can weather some pretty bad things. He's in the best possible place to get the job done. They'll take care of each problem one by one and although his stay will be an extended one you will have him home with you when he's better. I hoping that by the time they have it all straightened out, his heart rhythms will settle down and he won't have to have a defibrillator, but if he needs one, then he will be in good company. Our Vice President has one, Dick Cheney.
We have several members here who have had very major problems and have come through it all.
So don't lose faith, he can recover from this. I hope you will keep in touch with us all here and let us know how things are going on a daily basis, if you can.
Take care of yourself through this. He's going to need your help when he gets home.
