摘　　要：目的探讨实时三维超声心动图(RT-3DE)评价二叶主动脉瓣(BAV)畸形的应用价值。方法 应用经胸二维超声心动图(2DE)和RT-3DE对41例BAV患者进行诊断,并与手术结果对照。结果 经RT-3DE检查的41例患者与手术结果一致,其中横裂式25例、纵裂式10例、斜裂式6例;经2DE检查的30例患者与手术结果一致。2例患者2DE观察不清晰的赘生物,RT-3DE显示为附着于主动脉瓣叶心室面的赘生物。结论 RT-3DE能够快速、直观、准确显示瓣膜结构,在BAV的诊断中可获得较2DE更丰富的空间信息,具有重要应用价值。Objective To observe the value of real-time three-dimensional echocardiography（RT-3DE） in diagnosis of congenital bicuspid aortic valve（BAV） deformity.Methods Totally 41 patients with BAV underwent two-dimensional echocardiography（2DE） and RT-3DE,and the results were compared with those of surgical operations.Results BAV deformities were diagnosed with RT-3DE in all patients and were consistent with the findings of operation,including horizontal type in 25 patients,longitudinal type in 10 patients,oblique type in 6 patients,while 30 patients diagnosed with 2DE.Excrescences in 2 patients found with 2DE were proved to be vague vegetation attached to the surface of aortic valve toward the ventricular with RT-3DE.Conclusion RT-3DE can promptly,intuitively and accurately depict the structure of aortic valve,show more spatial information than 2DE in diagnosis of BAV.
