Tricuspid Valve Disease

On this page:

Definition

  • Tricuspid atresia is a congenital heart disease in which blood is unable to flow from the right atrium to the right ventricle because the tricuspid valve is absent or abnormally developed.
  • Tricuspid regurgitation (tricuspid insufficiency) is a disorder characterized by a backward flow of blood across the tricuspid valve which separates the right lower heart chamber (ventricle) from the right upper heart chamber (atrium).

Causes

  • Tricuspid atresia
    • Congenital heart disease
  • Tricuspid regurgitation
    • Damage to the valve itself
    • Enlargement of the right ventricle due to failure of the right ventricle.
    • Rheumatic fever
    • Medications for weight loss e.g. "Phen- fen" (phentermine and fenfluramine) or dexfenfluramine
    • Carcinoid tumor

Symptoms

  • Tricuspid atresia
    • Cyanosis (bluish discoloration of skin) due to the mixing of deoxygenated blood with the normally oxygenated blood in the aorta.
    • Shortness of breath (dyspnea)
  • Tricuspid regurgitation
    • Cyanosis (bluish discoloration of the skin)
    • Easily fatigued
    • Shortness of breath (dyspnea)
    • Clubbing of fingers or toes
    • Pulsations in the neck vein
    • Swelling of the abdomen, feet and ankles
    • Fatigue, tiredness and weakness

What You Can Do

  • Tricuspid atresia
    • Various surgical approaches have been developed. These include creating a shunt (or bypass) from the aorta to the pulmonary arteries. Another surgical approach to rectify this defect is Fontan operation which is a definitive treatment. In this procedure the systemic venous return is connected to the pulmonary arterial tree.
  • Tricuspid regurgitation
    • If the condition is asymptomatic, no treatment is required
    • Surgery may be needed to replace or repair the tricuspid valve
    • Treat streptococcal infections promptly to prevent rheumatic fever
    • Take prophylactic antibiotics before any dental work or invasive procedure to prevent the bacteria from causing endocarditis of weakened heart valve.
