Mitral click murmur syndromes are a group of cardiac conditions characterized by abnormal sounds and rhythm in the heart. Synonyms for this condition include mitral valve prolapse, click murmur syndrome, and systolic click murmur syndrome. These terms are often used interchangeably to describe the same set of symptoms and abnormalities observed during cardiac examinations. Mitral valve prolapse refers to the excessive movement or bulging of the mitral valve leaflets into the left atrium during systole. Its accompanying click and murmur sounds can be heard as the abnormal valve movement causes turbulent blood flow. Overall, these synonyms help describe and diagnose various manifestations of the same underlying heart condition.
