I am so sorry I was not here to help you out with your questions as I had major surgery on 8/16 and am just getting back into the swing of being online. I do hope your husband had his pericardectomy and that he is doing well. I hope that you are hanging in there and as a wife I understand what it is like to have your husband dx with a serious problem.
My husband has Crohn's Disease, had Prostate Cancer and coming up on the 5 year post op mark and just last September was dx with cardiomyopathy. Since he was 29 I have worried about him but the cardiomyopathy through me for a loop as I never thought he would develop a heart problem
Blessings to you and be well.
