| Abstract |
|
To evaluate the effectiveness of transesophageal echocardiography (TEE) for detecting potential intracardiac sources of cerebral emboli. We used both TEE and precordial conventional transthoracic echocardiogyrphy (TEE) in 27 patients with cerebral infarction. Group 1 had no clinical cardiac abnormality. And group 2 had cardiac abnormalities upon clinical examination. In group 1 (N= 18), TEE defined morphologic abnorrnalities in six patients (three with atrial appendage thrombus, two with patent foramen ovale, one with atrial septal aneurysm), whereas precordial echocardiography none. Although both echocardiogrpahic techniques revealed cardiac abnorrnalities in eight patients out of group 2 (N=9) only TEE could disclose left atrial appendage thrombus in six patients. We suggest that patients of cerebral infarction. Without demonstrable causes by conventiona studies including two-dimensional echocardiography. Should undergo TEE with the Valsalva maneuver. |
