| 目的 探讨经胸实时三维超声心动图（RT-3DE）诊断二尖瓣关闭不全的价值。方法 随机选取95例经手术确诊的二尖瓣关闭不全患者，对所有患者术前均行二维超声及RT-3DE检查，并与手术结果进行对比，评价二者诊断准确率的差异。结果 对95例患者均成功采集RT-3DE图像。95例中，风湿性心脏病二尖瓣狭窄合并二尖瓣关闭不全48例，二维超声与RT-3DE对其诊断准确率均为100%（48/48）；二维超声与RT-3DE诊断二尖瓣脱垂、二尖瓣腱索断裂、二尖瓣瓣裂、二尖瓣穿孔的准确率的差异均有统计学意义（P均<0.05）。结论 RT-3DE操作简便，成像速度快，三维图像细致，诊断准确率高于二维超声，是二尖瓣外科手术治疗前重要的检测手段。 |

| Objective To explore the application value of real-time three-dimensional echocardiography (RT-3DE) technology in the diagnosis of mitral insuffciency. Methods Ninety-five hospitalized patients with mitral insuffciency underwent the conventional two-dimensional echocardiography and RT-3DE images. Then the comparison with surgical results was made to evaluate the accuracy. Results The three-dimensional images of 95 patients were successfully captured by RT-3DE. Among them, 48 patients suffered rheumatic heart disease mitral valve lesion. The diagnostic accuracy of the conventional two-dimensional echocardiography and RT-3DE were 100% (48/48). The differences of accuracy in diagnosis of non rheumatic mitral insufficiency, mitral chordae tendineae fracture crack, mitral valve prolapse and mitral valve perforation were statistically significant (all P<0.05). Conclusion The RT-3DE is easily operated that features as fast imaging, clear three-dimension and high diagnostic accuracy, which provides an important preoperative examination for mitral valve surgery. |
