Medical research has found that the prevalence of mitral valve
prolapse is substantially greater in patients with autoimmune thyroid
disorders such as Graves' Disease and Hashimoto's Thyroiditis. According
to the About.com Heart Surgery Forum, MVP is the most common heart valve
abnormality, with estimates ranging from 2 million or more Americans
diagnosed with this condition, and most are women (about 80%).
When you have MVP, one or both valve flaps are enlarged. When the heart
contracts or pumps, the flaps don't close smoothly or evenly. Instead,
part of one or both flaps collapses backward into the left atrium. This
sometimes allows a Mitral Valve Prolapse small amount of blood to leak
backward through the valve and may cause a heart murmur.
Major Symptoms of MVP include:
Pounding, fast heartbeat
Low tolerance for exercise
Shortness of breath
