Due to persistent nature of this cough, a computerized tomography (CT) scan of the chest was performed that revealed a large (4.5 cm) right ventricular (RV) mass and pericardial effusion (Figure 1()).

Preoperative 2D echocardiogram confirmed a large 5.5 x 7.5 cm mass that was intimately associated with right ventricular free wall encroaching upon the AV groove and interfering with the tricuspid valve (TV) mechanism (Figure 2()).
