Percutaneous coronary intervention with catheter aspiration followed by surgical excision successfully treated a patient presenting with acute STEMI caused by left atrial myxoma embolization.
Case Report (n=1)
This case highlights a rare presentation of left atrial myxoma as acute STEMI due to coronary embolism, which was successfully managed with catheter aspiration and surgical excision.

May inform rare myxoma-related STEMI management; hypothesis-generating and requires prospective validation.
Primary 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.

Jayaprakash et al. (2015) conducted a case report in Acute inferior wall STEMI caused by left atrial myxoma embolization (n=1). Percutaneous coronary intervention with catheter aspiration followed by surgical excision was evaluated. Percutaneous coronary intervention with catheter aspiration followed by surgical excision successfully treated a patient presenting with acute STEMI caused by left atrial myxoma embolization.
