A 84-year-old woman underwent aortic root replacement with stentless bioprosthesis and coronary artery bypass grafting. Four years later, she presented with dyspnea. Transthoracic echocardiography revealed aortic regurgitation, dilation and dissection of the sinus of Valsalva. A Bentall operation was performed by using prosthetic graft and bioprosthetic valve. Intimal tear caused the aortic wall dissection and aneurysm of the Freestyle valve.

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.
