I am a 38-year-old woman who was diagnosed six years ago with mitral valve prolapse with mild regurgitation and aortic valve sclerosis. Is it common to have both heart conditions at the same time? I am a bit upset because my cardiologist never told me about the aortic sclerosis, just mvp, and the only reason I know is because the technician left my file open and I read the report. I've read it's quite rare to have aortic valve sclerosis at my age, that it could be congenital or caused by rheumatic fever. This makes sense in my case because when I was 16, I was extremely ill with what was thought at the time to be bronchitis, then developed a week later sudden severe arthritis in my big toe joints. I couldn't walk for two weeks and then it basically went away overnight.
