Tricuspid regurgitation: new evidence on a forgotten valve disease. Rev.Urug.Cardiol. [online]. 2015, vol.30, n.3, pp.312-325. ISSN 0797-0048.

Tricuspid regurgitation is the most common pathology of the tricuspid valve. In the majority of cases it is secondary to diseases producing right ventricular overload. Less frequently it is primary, acquired or congenital. A mild tricuspid regurgitation is frequent in healthy people and has a benign course. There are moderate and severe forms, that regardless the etiology may constitute a clinical challenge for physicians. Diagnostic is based on echocardiography that also allows its quantification. Medical treatment is symptomatic and pathophysiologic. In the last years the importance of considering surgery while operating left valves was established. The results are auspicious to repair instead of replacement. Nevertheless, replacement with a bio prosthesis or a mechanical valve may be required if native tricuspid valve has organic damage. Chronic overload may damage the right ventricle in an irreversible way. Tricuspid regurgitation increases mortality significantly.
