This is a question that has been bugging me for a while and I thought I might share it with you guys...my grandfather recently survived a burst aorta which they said might have had something to do with his RA. My rheumatologist, who also treats my grandfather said to me after it happened that it might be wise every once in a while making sure I was also okay in that department. This scares me a little, as I am only a young woman with a child. I know that with AS it can affect the heart valves as well as other parts of your body...can this cause an aortic dissection? Does anyone know the answer?
