A 57-year-old man presented with a one-month history of dyspnea. Computed tomography revealed a pulmonary embolism, and echocardiography revealed multiple linear floating thrombi in the right atrium. An urgent surgical thrombectomy was performed, and most of the thrombi in the right atrium and bilateral pulmonary arteries were removed under cardiopulmonary bypass. The thrombi in the right atrium adhered to the linear Chiari networks. The patient was treated with rivaroxaban uneventfully and subsequently discharged on postoperative day 26. Herein, we report a case of right atrial thrombi and pulmonary embolism likely augmented by the Chiari network, which was successfully treated with surgical thrombectomy.
