Tricuspid Regurgitation

Epidemiology

  • xxx

Etiology

  • Sinus of Valsalva Aneurysm (see [[Sinus of Valsalva Aneurysm]])
  • Trauma
    • Tricuspid valve regurgitation secondary to blunt chest trauma from a motor vehicle accident may remain asymptomatic for extended periods of time following injury. Gradual rupture of chordae tendinae, papillary muscle, and valve leaflets may eventually lead to right heart failure. In this patient, the echocardiogram shows significant tricuspid insufficiency, and cardiothoracic surgery consult for valve repair, in view of worsening symptoms, is indicated.

Clinical

  • Systolic Murmur (see [[Heart Murmurs]])
