Chapter 11. Tricuspid & Pulmonic Valve Disease
Sections: Tricuspid Valve Disease, Pulmonic Valve Disease.
Topics Discussed: pulmonary valve disorders; tricuspid valve disorder.
Excerpt:"Tricuspid regurgitation most frequently occurs with a structurally normal tricuspid valve (functional tricuspid regurgitation), which is the result of a dilated right ventricle and tricuspid annulus and papillary muscle dysfunction.Tricuspid valve disease can be difficult to recognize clinically. The symptoms may be overshadowed by associated illness, such as
systemic lupus erythematosus, infective endocarditis, trauma, or
neoplasia. The dominant presenting features may be symptoms that
are usually not considered cardiac in origin: abdominal discomfort,
jaundice, wasting, and inanition. In addition, patients with associated cardiovascular
disease may have nonspecific symptoms (exertional dyspnea and fatigue
in mitral stenosis) that obfuscate the diagnosis and deflect the
suspicion of tricuspid valve disease. In patients with mitral stenosis,
for example, tricuspid valve disease protects the pulmonary circulation
and exertional dyspnea, pulmonary edema, and hemoptysis are less
commonly reported, although a history of excessive fatigue may be elicited.
Most often, however, the history is insufficient to diagnose tricuspid
valve disease, and only a careful physical examination provides
the necessary clues.Because the..."
