An 83-year-old man was transferred to our hospital with cardiac tamponade and suspected cardiac tumor detected by enhanced CT. Coronary angiography showed a coronary aneurysm of 50 mm ID on the left circumflex artery. An emergency surgery was performed to excise the aneurysm, and a fresh thrombus occupying the efferent artery was observed. Both the afferent and efferent vessels were closed by suture. The patient made an otherwise uneventful recovery. This case featured a fresh red thrombus formed in fistulous outflow of the coronary aneurysm that seemed a direct cause of rupture.
