Abstract
Of the 400,000 new strokes in the United States each year, approximately 85% are due to cerebral infarction, and about 15% of these are from cardiogenic embolization. Emboli from cardiac sources often cause a severe neurological deficit or death. The frequency of these devastating events would likely be reduced if the offending cardiac lesions were adequately recognized and treated. Recently, noninvasive cardiac imaging has expanded our ability to obtain morphological, functional, and metabolic information of the heart and thus diagnose and assess a variety of cardiac conditions, many of which have been implicated as potential causes of cerebral embolization or hypoperfusion. These imaging techniques differ widely in the information they offer, and their use should be optimized in the pursuit of associated cardiac disease in patients with acute focal cerebral ischemia. We believe the use of two-dimensional echocardiography in older patients with focal cerebral ischemia should be limited to those with clinical clues of heart disease. Two-dimensional echocardiography should be considered in all patients younger than 45 years old with otherwise unexplained focal cerebral ischemia. Transesophageal and contrast echocardiography should be used in selected individuals, particularly when the transthoracic images are technically inadequate for the evaluation of mitral and aortic prosthetic valves or vegetations, or whenever there is need for better visualization of the left atrial appendage or interatrial septum, or when a right-to-left shunt is suspected.
