Both transthoracic (TTE) and transoesophageal (TOE) echocardiography are used routinely to investigate ischaemic stroke. We retrospectively assessed the incidence of abnormalities on TTE/TOE and whether an abnormal TTE/TOE result could have been predicted on the basis of ancillary tests and clinical cardiological examination. Data from 428 patients were analysed. The diagnostic yield of TTE was 12%. For TOE there was a diagnostic yield of 40% in tests actually performed. Overall, echocardiography altered management in 5% of patients. A significant correlation was found between clinical cardiac disease, stroke subtype and the diagnostic yield of TTE. We conclude that the vast majority of abnormal findings occur in patients who already have clinical evidence of cardiac disease. This suggests that the use of these tests should not be "routine", but determined on an individual patient basis.
经胸超声心动图（TTE）和经食管超声心动图（TOE）均常规用于缺血性脑卒中的检查。我们回顾性评估了 TTE/TOE 的异常发生率，以及异常 TTE/TOE 结果是否可以根据辅助检查和临床心脏检查来预测。分析了 428 例患者的数据。TTE 的诊断率为 12%。对于实际进行的 TOE 检查，诊断率为 40%。总的来说，超声心动图改变了 5%患者的治疗方案。临床心脏疾病、脑卒中亚型与 TTE 的诊断率之间存在显著相关性。我们的结论是，绝大多数异常发现发生在已经有临床心脏疾病证据的患者中。这表明不应将这些检查作为“常规”使用，而应根据患者个体情况来决定。
