| 目的 探讨实时三维超声(RT-3DE)在二尖瓣叶裂(MVC)诊断中的价值。 方法 对17例经二维超声心动图诊断MVC的患者在左心室长轴切面和二尖瓣短轴切面实施RT-3DE全容积显像,在三个方位(冠状位、矢状位、水平位)、六个方向对图像进行剖析观察,对二尖瓣瓣叶裂进行定位诊断,测量裂口宽度及长度,观察裂口与周围结构的空间位置关系。 结果 RT-3DE全容积图像可以清晰显示瓣叶裂的位置、宽度、长度及裂口宽度随心动周期的变化及其与周围腱索、主动脉瓣的空间位置关系。 结论 RT-3DE能为超声医生对MVC的诊断提供更明确的诊断依据,为心脏外科医生的手术方式的选择提供更全面的参考信息。 |

| Objective To explore the value of real-time three-dimensional echocardiography (RT-3DE) in diagnosis of mitral valve cleft (MVC). Methods Seventeen patients with two-dimensional echocardiography diagnosed MVC underwent RT-3DE in left ventricular long-axis and short-axis. RT-3DE images were analyzed in three planes: Coronal, sagittal, horizontal plane and six directions to diagnose the specific location, and the width and depth of MVC were measured, the space relationship between the cleft and other structures was observed. Results RT-3DE image clearly displayed the location, the width and depth of mitral valve cleft, the changing of width with cardiac cycle, as well as the space relationship among chordae, papillary muscle and artery. Conclusion RT-3DE can provide more specific basis in diagnosis of mitral valve cleft, and is important in decisions regarding mitral valve surgery. |
