Fibrosis means scar tissue.
Hi Kathy----I am also a former user of the diet drugs Fen-Phen. Your echo results sound pretty good to me. I have had several echos that show left ventricle dilatation, concentric hypertrophy and mitral 3+, tricuspid 3 and aortic 1+ regurgitation. I also have congestive heart failure now. Are you having any symptoms like shortness of breath, swelling of the feet or ankles, or anything like that? I also have something on or in my mitral valve, fibrosis, thickening, or something of that nature. Dr. if you happen to read this, what is fibrosis anyways???? Your ejection fraction is very good also. I really don't think that you have anything to worry about at this point, but it might not be a bad idea to keep an eye on the aortic regurgitation---maybe yearly, or what ever your doctor suggests. Good luck to you!!
No, this is almost certainly not due to the Phen-Fen. The mitral valve is the one affected by Phen-Fen and mild aortic insufficiency is nothing to be concerned about. Of course there are some hungry class-action lawyers who would love to have a talk with you anyways....
