Cerebrovascular manifestations of tumors of the heart

Abstract

Primary tumors of the heart, most commonly myxoma, are an uncommon cause of ischemic stroke and intracranial aneurysms. The tumors may occur in any age group but are most frequently detected in middle-aged persons with an atypical or cryptogenic stroke. While some patients will have a history of cardiac or constitutional symptoms, in many cases ischemic stroke will be the initial manifestation of the cardiac mass. Myxomas are the most common cardiac tumors, and valvular fibroelastoma is also a potential cardiac cause of stroke. Among patients with stroke, the most common location for a myxoma is the left atrium. Elevations of inflammatory markers provide clue for a myxoma. Cardiac imaging is the most definitive diagnostic study. Treatment centers on surgical removal of the cardiac mass may be curative.
