mitral valve prolapse
Also written as: MVP — mitral valve prolapse
Condition where mitral valve leaflets bulge backward into the left atrium during ventricular contraction.
Full Definition
Mitral valve prolapse (MVP) is a cardiac condition in which one or both leaflets of the mitral valve bulge (prolapse) backward into the left atrium during systole. This occurs due to abnormal mitral valve structure, often involving redundant or thickened valve tissue and elongated chordae tendineae. MVP is the most common valvular abnormality, affecting 2-3% of the population, with a higher prevalence in women. Most cases are benign and asymptomatic, though some patients may experience chest pain, palpitations, or fatigue. Complications can include mitral regurgitation, infective endocarditis, and rarely, sudden cardiac death. Diagnosis is typically made by echocardiography, which may reveal the classic mid-systolic click and late systolic murmur.
Usage
Usage note: Commonly abbreviated as MVP; specify degree of associated regurgitation when present.
