Narrowing of the opening of the tricuspid valve, usually caused by a previous attack of rheumatic fever. Tricuspid stenosis is uncommon and often occurs with another heartvalve disorder. For example, tricuspid incompetence may also occur in intravenous drug users who have a bacterial infection of the heart. Tricuspid stenosis causes enlargement of the right atrium. The symptoms and diagnosis are similar to those of tricuspid incompetence. Treatment is with diuretic drugs and sometimes a digitalis drug. Heart-valve surgery is sometimes needed.
