目的探讨超声心动图在诊断主动脉-左室隧道中的临床应用价值.方法对6例主动脉-左室隧道的超声心动图资料及临床特点进行回顾性分析,并结合国内外相关文献综述报道的147例进行综合分析.结果 6例患者均经手术证实,超声心动图特征主要表现为升主动脉与左心室间主动脉瓣膜旁侧的异常通道,通道内可见高速往返血流,伴或不伴主动脉瓣受累.根据Hovaguimian分型:Ⅰ型2例,Ⅲ型2例,Ⅳ型1例,Ⅱ型1例(为术后再通).结合文献共报道主动脉-左室隧道153例,超声诊断准确率79.6％,误诊率17.1％,漏诊率3.3％.结论超声心动图是术前无创性诊断主动脉-左室隧道的首选方法,并能准确分型及描述心内结构受累情况.

Objective To evaluate the clinical value of echocardiography in the diagnosis of aorticoleft ventricular tunnel.Methods The echocardiographic and clinical characteristics were retrospectively analyzed in 6 patients with aortico-left ventricular tunnel we reported and 147 cases that documents reported.Results Six patients were confirmed by operation.The main echocardiographic characteristics of aortico-left ventricular tunnel were as follows:An abnormal communication began in the ascending aorta above the level of the coronary arteries,bypassed the aortic valve,and terminated in the left ventricle.The color Doppler flow imaging demonstrated to-and-fro flow,with or without aortic valve involvement.According Hovaguimian and his colleagues,2 cases were type Ⅰ,2 cases were type Ⅲ,1 case was type Ⅳ,1 case was type Ⅱ (showed as recanalization).Base on all of the 153 patients that we and documents reported,the accuracy rate of ultrasound diagnosis was 79.6％,the misdiagnosis rate was 17.1％,and missed diagnosis rate was 3.3 ％.Conclusions Echocardiography is the non-invasive and sensitive tool in the diagnosis of the type of aortico-left ventricular tunnel and structure of cardiac involvement,and is the preferred method for preoperative.
