Coronary artery embolization is an extremely rare and potentially lethal complication of atrial myxomas. We observed of a case of left atrial myxoma associated with acute anteroseptal and inferior myocardial infarction. A transthoracic echocardiographic study revealed the presence of an echogenic, mobile mass, compatible with myxoma in the left atrium. Coronary angiography disclosed abrupt occlusions of the distal left anterior descending artery and the right coronary artery. The tumor was successfully removed surgically after medical treatment and the patient was doing well post operatively at 6-month follow-up.
