ObjectiveTo evaluate the diagnostic values of transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) in cardiogenic embolic cerebral infarction.MethodsFifty patients with occult cerebral infarction who were admitted to the hospital between June 2015 and June 2016 were selected as research subjects. The patients were diagnosed by transesophageal echocardiography and transthoracic echocardiography. Diagnostic data were compared to analyze the values of the two diagnostic methods.ResultsSixteen out of fifty patients were diagnosed as cardiogenic embolic cerebral infarction by TEE (32%), including two cases of aortic plaques, six cases of atrial septal defect, two cases of atrial septal aneurysm, two cases of patent foramen ovale, one case of left atrial spontaneous echo contrast, one case of mitral prolapse and two case of mitral stenosis. Four cases were diagnosed as cardiogenic embolic cerebral infarction by TTE (8.0%), including one case of patent foramen ovale, one case of left atrial spontaneous echo contrast, one case of mitral prolapse and one case of mitral stenosis. The difference was statistically significant (P<0.05). The main difference of TEE and TTE was detection of aorta atheromatous plaques and atrial septal lesions. Aortic atheromatous plaques of two cases and atrial septal lesions of eight cases were missed in the diagnosis by TTE.ConclusionDetection and diagnosis of cardiac embolic cerebral infarction with TEE is highly accurate and advantageous. Therefore, TEE is worth promotion and application.
