Left atrial myxoma: association with acute coronary embolization in an 11-year-old boy.

An 11-year-old boy had clinical signs of an acute inferior wall myocardial infarction. On echocardiography, a left atrial myxoma was demonstrated. Coronary artery embolization from myxoma was confirmed by selective coronary arteriography. The tumor was removed 12 days after acute coronary embolization. The clinical value of echocardiography is demonstrated in this report of a successful surgical excision of left atrial myxoma in a child with a myocardial infarction due to tumor embolization.
