Mitral valve prolapse often presents with a characteristic sound known as a "click" during systole, which can sometimes be associated with a late systolic murmur if significant regurgitation is present. This sound occurs because the mitral valve leaflet moves back into the left atrium during ventricular contraction, which is typically described as a systolic click.

The presence of a systolic murmur in patients with mitral valve prolapse is related to the regurgitant flow that occurs when the prolapsed leaflet prevents the valve from closing completely. Therefore, recognizing that a systolic murmur can be indicative of mitral valve prolapse is vital for the diagnosis and management of this condition, making it an important characteristic sound associated with this pathology.
