I have it too and I have MVP. I was told the same as you...it's not serious but I disagree due to much research. Your "flap" isn't closing the whole way causing the blood to back flow. This makes the heart work harder. Anything that makes the heart work harder is bad. Eventually it will either get enlarged or fail. I'm not talking next week so calm down.

Down the road...and some people do have valve replacements to correct this. So, keep your heart as healthy as a horse..plenty of exercise, eating right and lower your stress and regular checkups. The healthier your heart the better it will tick and the stronger it will be.
