Mitral click murmur syndrome, also known as systolic click-murmur syndrome or mitral valve prolapse syndrome, refers to a condition characterized by a clicking sound followed by a murmur heard during the systolic phase of the heartbeat. This syndrome is primarily associated with abnormalities in the mitral valve, which is one of the four valves in the heart responsible for regulating blood flow between the left atrium and the left ventricle.
In individuals with mitral click murmur syndrome, the mitral valve's leaflets and supporting structures are slightly stretched or elongated, causing them to bulge into the left atrium during systole. This bulging can result in a clicking sound as the leaflets snap back into place at the end of systole, creating an audible click. Following the click, a murmur may arise due to abnormal blood flow across the disrupted valve structure.
While mitral click murmur syndrome is generally considered a benign condition, it can sometimes be associated with other cardiovascular abnormalities, such as mitral regurgitation or arrhythmias. Symptoms of the syndrome can vary from individual to individual but commonly include chest pain, palpitations, fatigue, and shortness of breath, while some individuals may remain asymptomatic.
Diagnosis of mitral click murmur syndrome is typically made through a thorough physical examination, where a healthcare provider listens for the characteristic click and murmur using a stethoscope. Additional tests, such as echocardiography, may be performed to assess the structure and function of the mitral valve.
Treatment for mitral click murmur syndrome often involves managing symptoms through lifestyle modifications, such as avoiding stimulants and managing stress levels. Medications may be prescribed to control any related conditions, such as arrhythmias or high blood pressure. In
