Many people have "leaking heart valves", a condition called Mitral Valve Regurgitation or Mitral Valve Prolapse
. Many live well into their 70's or 80's with this condition. A leaking valve, in itself, is not a life-threatening problem. However, the interrupted blood flow from one of the above-named problems can cause circulatory problems in the heart and major blood vessels. Talk your concerns over with your Doctor.
