To determine, by means of transesophageal echocardiography (TEE), the risk factors for intracavitary thrombosis or prethrombotic state and for embolic accidents in patients with atrial fibrillation.
We studied 49 patients with chronic atrial fibrillation, submitted to clinical examination, EKG, chest X-ray, and TEE.
Thirty percent of patients had valvopathies, 29% myocardiopathies, intracavitary thrombus or prethrombotic state were found in 37%, 40% of them had embolic accidents. We did not find statistical significance between myocardiopathies and valvulopathies. The left atrial diameter did not preview embolic accidents. We have observed 6 patients without structural cardiopathies, three of them presented embolic events, and one prethrombotic state.
Embolic phenomena are inherent to atrial fibrillation and independent of structural cardiopathies, with indication to prophylactic use of oral anticoagulants.
通过经食管超声心动图（TEE）确定心房颤动患者发生心腔内血栓形成或血栓前状态以及栓塞事件的危险因素。
我们研究了49例慢性心房颤动患者，对其进行了临床检查、心电图、胸部X线和TEE检查。
30%的患者患有瓣膜病，29%患有心肌病，37%发现有心腔内血栓或血栓前状态，其中40%发生了栓塞事件。我们未发现心肌病和瓣膜病之间有统计学意义。左心房直径不能预测栓塞事件。我们观察到6例无结构性心脏病的患者，其中3例出现栓塞事件，1例出现血栓前状态。
栓塞现象是心房颤动所固有的，与结构性心脏病无关，提示应预防性使用口服抗凝剂。
