[A surgical case of cor triatriatum complicated by arterial multiple embolism in adult].

A 30 year old male developed sudden chest pain while driving his car and was subsequently admitted to our hospital. Cardiac catheterization and arteriography revealed multiple embolism in the right coronary artery, the right renal artery and the both popliteal arteries. Thrombus was also suspected in the left atrium by echocardiography. Emergent surgery was performed to prevent recurrence of embolism, IA type cor triatriatum (according to the Lucus-Schmidt classification) and 3 x 1 cm thrombus in the accessory chamber was found. The thrombus was extracted and the abnormal septum was satisfactorily resected. The postoperative course was favourable and the patient returned to the community after discharge. Cases of cor triatriatum complicated by multiple arterial embolism are very rare and have not been reported in Japan yet. For this reason we present this case with additional discussion from literature.
