| 目的 在二维 (2D)基础上应用三维实时超声心动图(RT-3DE),探讨RT-3DE在评价人工瓣功能方面的临床应用价值。方法 应用Philips IE33型彩色多普勒超声诊断仪, 对23例受检者进行了实时三维超声心动图检查,其中二尖瓣位18例,主动脉瓣位5例。结果 23例人工瓣均获得较清晰的三维图像。20例人工瓣功能正常。3例功能异常,其中2例为人工瓣瓣周漏, 另有1例为二尖瓣位人工瓣血栓导致梗阻。结论 RT-3DE在2DE基础上, 可获得更丰富的空间信息,可以对2DE做出有益的补充。 |

| Objective To assess the clinical value of real-time three-dimensional echocardiography (RT-3DE) for evaluating the function of mechanical prosthetic valves. Methods Twenty-three patients, in which 18 patients with mitral valve prosthesis, and 5 with aortic valve prosthesis were examined with Philips IE33 to evaluate morphology and function of the mechanical protective valves. Results All the prosthetic valves of the twenty-three patients could be successfully observed by RT-3DE. Twenty of them worked normally. Other three cases were observed dysfunction, with perivalvular leakage in one case and obstruction of the prosthetic valve by thrombosis in another case. Conclusion As a new technique, RT-3DE can provide more spatial information than those of the 2DE in mechanical heart valve and offer the useful supplement to 2DE. |
