I am with kfay on this one--justwaiting has chosen a tissue valve. Graphic details of surgery or quick quips about taking a little pill are probably not what is needed to help justwaiting to prepare for surgery.
Kathy--Regarding pericarditis if you have a redo--- For my redo, they removed my pericardium altogether. I don't know how common that is, but then you won't have that problem.
