Abstract：
BACKGROUND:The aortic atherosclerotic debris is considered a high risk embolic source, being an independent predictor for cerebrovascular ischemia. The incidence is higher in the elderly and in patients with coronary artery disease. Transesophageal echocardiogram (TEE) is an important diagnostic tool that allows its detection. OBJECTIVE:To describe characteristics of patients with ischemic stroke and echocardiographic diagnosis of aortic debris. PATIENTS AND METHODS:We analyzed the group of patients with debris diagnosis in 209 TEE performed between 01/01/99 and 31/05/02, in 835 consecutive ischemic events. The information was collected from the Stroke Database of the Neurology Department of Policlinica Bancaria. RESULTS:TEE was accomplished in 25% of all assisted events. The mean age was 66.56 years (SD 11.22). In 30 studies (14%) aortic debris was detected. In this group of patients, 26 men and 4 women, was also found: plaques grade IV 60%, left atrial dilatation 40% and spontaneous echo contrast 20%. The most frequent risk factors were hypertension, dislipemia and smoking, with no significative difference compared to the group without debris. 40% had a prior cerebrovascular event. They presented with clinical subtype LACI 53%, PACI 27%, POCI 17%. 63% of patients had lacunar infarct (53% anterior and 10% posterior). CONCLUSION:The contribution of TTE for detection of embolic sources is relevant. A high percentage of the population with echocardiographic diagnosis of aortic debris, had a lacunar infarct, defined radiologically and by clinical features.
