“…5 Coronary artery embolism with acute STEMI as the initial presentation of cardiac myxoma is extremely rare. 5,9 This is attributed to the perpendicular position of the coronary ostia in relation to the aortic blood flow and the protection of the ostia by the aortic leaflets in systole. However, villous myxomas form emboli as a result of their tendency to fragment, often resulting in small tumoral particles that can pass through the coronary apertures.…”

a b s t r a c tPrimary cardiac neoplasms are very rare, with an incidence less than 0.2% in unselected patients at autopsy. Of these, cardiac myxomas are the most common benign cardiac tumors in the adult. Atrial myxomas are a rare source of coronary artery embolism. Coronary embolism as the first presentation of cardiac myxoma is extremely uncommon. We report a case of acute inferior wall ST elevation myocardial infarction (STEMI) caused by embolization of the tumor fragment from left atrial myxoma into the left circumflex coronary artery. The patient was successfully treated by percutaneous coronary intervention with catheter aspiration of the embolized tumor fragment followed by surgical excision of the tumor.

Probable Left Atrial Myxoma Presenting as Concurrent Cerebral and Myocardial Infarctions

Concurrent cerebral and coronary artery embolization is a theoretically possible, but extremely rare complication of an atrial myxoma. We present a paitent with a left atrial mass (a probable myxoma) who presented with concurrent cerebral and myocardial infarctions due to emboli of tumor origin. An 84-year-old woman presented with an acute cerebral infarction of the middle cerebral artery territory. Several hours after admission, she complained of chest pain consistent with a myocardial infarction. Transthoracic and transesophageal echocardiographic studies revealed the presence of a large, mobile, heteroechoic mass with a few daughter nodules in the left atrium, compatible with a myxoma. Coronary angiography disclosed subtotal occlusion of the ramus intermedius branch and visible tumor vascularization adjacent to the right coronary artery. With medical treatment, including anticoagulation, the patient was stabilized and had an uneventful clinical course for the ensuing 6 months since discharge.
