Successful Resection of a Posterior Tricuspid Leaflet Lipoma and Reconstruction of the Tricuspid Valve.

Abstract

We present a case with posterior tricuspid leaflet mass involving a tricuspid annulus and the right ventricle. Echocardiography demonstrated a lobulated mass arising from posterior tricuspid valve and partially obstructing the orifice of the tricuspid valve. At the operation, a yellowish, walnut-sized mass arising from the posterior tricuspid leaflet tightly adherent to the posterior tricuspid annular was excised en bloc with posterior tricuspid leaflet and adherent ventricular myocardium and annulus. Autologous pericardium was used to repair the valve. The pathologic analysis confirmed the mass as a lipoma. In the follow-up, no recurrent mass or symptom was found.
