Click Murmur Syndrome (Mitral Valve Prolapse)
The Click-murmur syndrome (aka Barlow’s syndrome) involves mitral valve prolapse, 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 is designed to prevent backflow of blood from the left ventricle into the left atrium. Mitral valve prolapse can often be detected by a doctor during examination of the heart and confirmed with an echocardiogram. (Mitral valve prolapse: Drooping down or abnormal bulging of the mitral valve’s cusps backward into the atrium during the contraction of the heart. Mitral valve prolapse is often an asymptomatic condition but it may be marked by mitral regurgitation with symptoms (as chest pain, fatigue, dizziness, dyspnea, or palpitations) with a tendency in some cases to endocarditis or ventricular tachycardia.
