components of the tricuspid valve apparatus (see Anatomy). The lesion may be classified as primary when it is caused by an intrinsic abnormality of the valve apparatus or as secondary when it is caused by right ventricular (RV) dilatation.
Common presenting complaints in patients with LV dysfunction include the following (see Presentation):
Dyspnea on exertion
Orthopnea
Paroxysmal nocturnal dyspnea
Ascites
Peripheral edema
Color flow Doppler echocardiography is a mainstay for evaluating tricuspid regurgitation (see Workup). Depending on the etiology and severity of tricuspid regurgitation, treatment may involve medication or surgical repair or replacement of the valve. (See Treatment and Medication.)
