超声心动图诊断主动脉左室通道

目的：分析主动脉左室通道的超声特征。方法：应用超声心动图检测6例主动脉左室通道患者。结果：在超声心动图检查中，6例较清楚显示主动脉根部与左室之间的异常交通，其中3例与手术结果一致，2例与造影结果一致。结论：超声心动图是诊断主动脉左室通道可靠的技术，可为选择治疗方案及评价预后提供重要依据。

Diagnosis of aortic left ventricular tunnel with echocardiography

Objective: To investigate echocardiographic manifestations of aortic left ventricular tunnel(ALVT). Methods: Examining a group of 6 patients with ALVT by using echocardiography. Results: Among the examinations of echocardiography manifestation, 6 cases comparatively displayed the abnormal tunnel between aortic left ventricle, three of which were consistent with the operation result, while two of which were consistent with the contrast exmination result. Conclusions: It is concluded that echocardiography which is the most reliable technique in the diagnosis of the aortic left ventricular tunnel has significance in making the therapeutic strategy and assessing the prognosis.
