Mild tricuspid regurgitation usually causes no symptoms, but some patients present with jugular venous pulsations due to increased jugular venous pressure.
As the severity increases, symptoms manifest themselves in two main ways.
Decreased cardiac output and peripheral stasis. Decreased cardiac output leads to weakness of the extremities and reduced exercise tolerance.
Peripheral stasis causes the patient to present (including jugular venous dilatation as described above) with epigastric pain, poor appetite, hepatomegaly, ascites, and lower limb oedema.
