What type of heart murmur is associated with mitral valve prolapse?

Mitral valve prolapse is characterized by a late systolic murmur due to the abnormal movement of the mitral valve leaflets during contraction of the heart. As the left ventricle contracts, the prolapsed leaflets can billow back into the left atrium, resulting in turbulence and a distinct sound that occurs later in the systolic phase. This late-systolic murmur is often preceded by a mid-systolic click, which is indicative of the sudden tension on the mitral valve apparatus as it prolapses.

Identifying the murmur associated with mitral valve prolapse is crucial, as it helps in diagnosing the condition and understanding its hemodynamic implications. While early diastolic murmurs are typically associated with conditions related to heart filling and blood flow after the ventricles relax, and continuous murmurs are related to conditions like patent ductus arteriosus, they do not pertain to mitral valve prolapse. Similarly, systolic ejection murmurs are linked to normal flow across outflow tracts and do not demonstrate the specific changes associated with mitral valve prolapse. The characteristics of the murmur directly relate to the pathophysiology of the valve's movement during the cardiac cycle, affirming the
