Background

  • 1 or more mitral valve leaflets bow into left atrium during systole
  • Most common valve disease in industrial countries (2.4% of pop.)
  • Myxomatous degeneration from connective tissue disorder

Clinical Features

Symptoms

  • Studies failed to demonstrate that chest pain, anxiety, or palpitations are associated with MVP
  • Symptoms related to autonomic dysfunction: fatigue, anxiety, exercise intolerance
  • If progresses to MR, CHF symptoms

Physical exam

  • Mid-systolic click
  • Late systolic murmur, crescendo into S2
  • May have associated physical features:
    • Pectus excavatum
    • Scoliosis
    • Low body weight
    • Marfanoid habitus

Differential Diagnosis

Valvular Emergencies

Evaluation

Workup

Diagnosis

Transesophageal echocardiogram of mitral valve prolapse
  • Echocardiogram is gold standard

Management
