Hi Mary, Welcome to Healing Well forum. We are happy to have you.
I am sorry about your diagnosis of pericarditis. I hope that someone can come along and answer your question shortly.
Hi...I don't know anything about Johns Hopkins other than it has a great reputation. I underwent a pericardiectomy a year ago if you need any info about the procedure. There is a lot of info on old threads here from patients. Let me know if I can help in any way! Good luck to you!
