Right atrial thrombus associated with combined valvular disease: Case report

A 77-year-old man had a large right atrial (RA) thrombus associated with a combined mitral and tricuspid valve disease. Echocardiography showed a larg e, immobile, non-homogeneous, irregularly surfaced mass in the dilated RA, and prolapse of the anterior mitral leaflet resulting in massive mitral reg urgitation. Computed tomography (CT) revealed a laminated structure with ca lcification and distinct margins, without invasion to the wall of the RA. O n the basis of these echo cardiographic and CT findings, a diagnosis of com bined mitral and tricuspid valvular disease complicated with RA thrombus wa s made. Removal of the RA thrombus, mitral valve replacement and tricuspid annuloplasty were performed simultaneously, with successful outcome.
