Mitral Valve Prolapse is a special type of heart valve problem. In this condition when the valve closes, it actually passes beyond the closure line into the left atrium. This causes the valve to leak.
People with Marfan Syndrome can suffer from leaking of the heart valves, Mitral Valve Prolapse. The leaks are often mild and require no treatment but sometimes surgery is necessary.
Children with Mitral Valve Prolapse are sometimes said to be more prone to dysautonomia - palpitations, sweating and feeling faint.
If the valve prolapses badly it can usually be repaired although sometime replacement is necessary.
