What's the difference between mitral vavle prolapse and a mild mitral valve leak?

prolapse vs leak. Mvp is a congenital disorder of the mitral valve where the collagen fibers that make up the valve are disorganized. It may or may not be associated with leakiness of the valve, which is simply what it sounds like - leaking blood backwards through the valve. People with mvp are more likely to develop leaky valves, but it's not a guarantee. An echocardiogram can tell you how leaky it is.
