I am not sure where to post this question. I have been seeing a cardiologist for almost three years now for a leaky mitral valve. I get echoes every 6 months. He has rated the amount of regurgitation mild at rest, moderate to severe at exercise. He has said we need to watch it and if necessary I may need surgery to fix it, but that I don't need surgery yet. I was fine with that..it's something that can be fixed and everything else about my heart is described as normal. I can live with the thought of having valve surgery if it will fix the problem. So I have been fine psychologically dealing with my heart condition until recently. I had an MRI of my heart a month ago and the cardiologist noted that I have grade I (mild) diastolic dysfunction. I got to looking back through my past echo reports and found in amongst all the numbers and descriptions that in September 06 it was also noted that I had mild DD. My cardiologist has never mentioned this or discussed it with me before. I got to reading about DD and it doesn;t sound good. One article made it sound like I won't be around much likely after 5 years, another comment from a Cleveland Clinic doc sounded like grade I DD is not much worse than being normal. I don't know what to think, but I have a heavy cloud of fear over me that I am going to gradually deteriorate and die in a few years. You would think the fact that I can ride my bike 15 miles w/o any problem would ease my angst, but it doesn't. I'm flat scared :-(............. DO any of you out there have any experience with DD and can offer me with some reassurance? Thanks. PJackson
