Mitral valve prolapse ejection fraction. Prior to the strict criteria for the diagnosis of mitral valve prolapse, as described above, the incidence of mitral valve prolapse in the general population varied greatly. Some studies estimated the incidence of mitral valve prolapse at 5 to 15 percent or even higher. One study suggested MVP in up to 35% of healthy teenagers. Recent elucidation of mitral valve anatomy and the development of three-dimensional echocardiography have resulted in improved diagnostic criteria, and the true prevalence of MVP based on these criteria is estimated at 2-3%. As part of the Framingham Heart Study, for example, the prevalence
Mitral valve repair still low) risk of stroke. One cardiac surgery professor said, "I think the only benefit is for cosmesis for the patient and the benefit is for marketing and growing our practices for ourselves because it’s a good way to grow one's practice." Robotic mitral valve repair operations are also being utilized throughout the United States. In the 2000s there have been several trials of a newer strategy of mitral valve repair that does not require major cardiac surgery. Through a catheter inserted in the groin, the valve leaflets are clipped together. This technique – percutaneous mitral valve repair – is
