Many physicians consider tricuspid regurgitation to be a rare condition they need to know little about. Other physicians so commonly encounter tricuspid regurgitation that they consider it normal. The reason for these diametrically apposed views is that the newest Doppler echocardiographic methods are extremely sensitive to even small degrees of tricuspid regurgitation, and this finding is often identified during ecbocardiographic testing for any reason. Therefore, physicians performing echocardiography on their patients consider this a very common condition. However, clinicians who do not think of tricuspid regurgitation often become aware of this diagnosis only in its most advanced form, and so they consider it a rare occurrence. Tricuspid regurgitation obviously is of clinical importance in its advanced stages, and tricuspid regurgitation recognized only echocardiographically is not hemodynamically significant in most instances. So when is tricuspid regurgitation important? The purpose of this review is both to clarity the important use of echocardiographic tricuspid regurgitation to noninvasively measure right ventricular pressure and to recall all the clinical situations in which tricuspid regurgitation should be considered important. © Williams & Wilkins 1994.
