Abstract

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.
