【摘要】 目的　探讨主动脉 左室隧道 (ALVT)的临床诊断及治疗。方法　对 6例ALVT行常规体检、心电图、X线胸片、二维超声心动图、心导管检查结果、外科手术治疗及术后随访结果进行分析。结果　 1.6例脉压差均增大并在胸骨左缘闻及双期杂音 ,4例并心功能不全 ;2 .5例心电图左室肥厚伴T ST改变 ;3.6例X线胸片示左心室增大 ;4 .4例超声心动图均显示主动脉根部与左室间的异常交通及血流 ;5 .6例均经左室造影显示ALVT的直接征象及造影剂返流左心室 ;6 .6例均经外科治疗证实为ALVT且手术补片缝合。结论　ALVT是一种少见的先天性心脏病 ,凡婴幼儿患儿以主动脉瓣关闭不全就诊 ,具有典型的主动脉关闭不全体征 ,应考虑ALVT的可能性 ,结合超声心动图及心导管检查予以确诊 ,一旦确诊宜早期手术。更多还原

【Abstract】 Objective To explore the diagnosis and treatment of aortico left ventricular tunnel(ALVT).Methods To analyze the clinical featues,laboratory examinations,management and outcomes in 6 patients with ALVT.Results 1.All patients had widened pulse pressure with systolic and diastolic murmur at 2 left intercostal spale 3rd,4 cases had congestive heart failure.2.Five cases had left ventricular by pertrophy and T ST change.3.All cases had left cardiomegaly by chest X ray.4.Four cases exibited the abnormal communication between the root of aortic and left ventricle by echocardiography.5.All showed the tunnel and blood regurgitation into the left ventricle by catheterization.6.All cases had surgical repair and were confirmed at surgery.Conclusions ALVT is a rare congenital heart disease.If a child has typical cilinical features of“aortic insufficiency”,we should consider the disease of ALVT.The diagnosis is made according to echocardiography and catheterization.Because ALVT can lead to progressive aortic regurgitation,it requires surgery as early as possible.更多还原
