An 80-year-old woman was scheduled to have an operation for uterus cancer. Echocardiography revealed a giant mobile mass in the left atrium with a stalk at posterior wall of the left atrium. There was no significant mitral disease. Due to the risks of sudden circulatory collapse and systemic emboli, an emergency operation was indicated. Right side of the left atrium was opened under cardiopulmonary bypass following median sternotomy. The mass was attached to the posterior wall, 1.5 cm medial to the right upper pulmonary vein, with a thin stalk as diagnosed preoperatively. The mass (4.2 x 3.4 x 3.4 cm) was removed very easily. Pathological analysis revealed that the mass was a thrombus mixed with fibrin. A possible cause would be paroxysmal atrial fibrillation and/or hypercoagulative status due to malignancy. Anti-coagulation therapy was initiated postoperatively to prevent recurrence of thrombus. The patient recovered and discharged uneventfully.
