Resumo: INTRODUCTION: Peripheral embolism is frequently related to a cardiac source of embolism. Transesophageal echocardiography (TEE) is a useful tool for identifying such sources. OBJECTIVES: Our laboratory has gained wide experience in TEE, with a large number of exams performed to search for a cardiac source of embolism. We therefore thought it would be useful to present our experience in the last 12 years following the introduction of the technique. METHODS: This was a retrospective study of 1110 consecutive patients undergoing TEE to search for a cardiac source of embolism, after an embolic event and a transthoracic echocardiogram. RESULTS: The patients' mean age was 53 +/- 14 years, 52% male. There was peripheral embolism in 5% of cases and cerebral embolism in the remainder. The exam identified a potential embolic source in 35.6% of cases, the most frequent diagnoses being intracardiac shunt at the atrial level (9.5%), atrial septal aneurysm (ASA) (6.6%), intracardiac thrombi (6.4%) and atherosclerotic plaques in the thoracic aorta (9.6%). The presence of ASA was frequently associated with patent foramen ovale (27%), which was more frequent in younger patients. Overall, we identified a cardiac source of embolism more often in elderly patients, with a predominance of atherosclerotic plaques in the aorta. ETE was more frequently diagnostic in patients with peripheral embolism, but there were no differences in terms of etiology. CONCLUSIONS: TEE is very useful to search for cardiac sources of embolism, especially in younger patients, in whom causes potentially treatable surgically or percutaneously can be identified. In elderly patients, therapeutic strategy will probably not be changed by the findings (mostly thrombi and atherosclerotic plaques). The presence of ASA and embolic events makes it essential to perform a thorough search by TEE for intracardiac shunts, which are frequently associated.
