Click-murmur syndrome

Mitral valve prolapse (also known as "Barlow's syndrome"), the most common heart valve abnormality, affecting 5-10% of the world population. Most patients have no symptoms and require no treatment, but some have fatigue and/or palpitations. The mitral valve prolapse can often be detected by a doctor during examination of the heart and confirmed with an echocardiogram. Patients are usually given antibiotics prior to any procedure which might introduce bacteria into the bloodstream, including dental work and minor surgery, because of an increased risk of infection of the abnormal heart valve.
