目的:探讨二尖瓣关闭不全的彩色多普勒超声诊断。方法:选取2013年10月-2014年10月铁力市朗乡镇卫生院收治的经过彩色多普勒超声诊断的二尖瓣关闭不全患者28例,分析其临床治疗方法资料。结果:超声心动图示二尖瓣返流程度:中度10例,重度18例。左心房内径(56.5±15.8)mm,合并三尖瓣中度以上返流2例。结论:超声心动图在明确二尖瓣返流解剖机制、病情发展的随访监测、手术干预治疗最佳时机的选择、内外科治疗效果评价等方面发挥越来越重要的作用。
Objective: To investigate the diagnosis of mitral regurgitation by color Doppler ultrasound. Methods: Twenty-eight patients with mitral regurgitation who were diagnosed by color Doppler sonography at Longxiang Town Hospital, Tieli City, from October 2013 to October 2014 were selected and their clinical treatment data were analyzed. Results: Echocardiography showed the degree of mitral regurgitation: 10 cases were moderate and 18 cases were severe. Left atrial diameter (56.5 ± 15.8) mm, merger tricuspid regurgitation in 2 cases. Conclusion: Echocardiography plays an increasingly important role in the anatomical mechanism of mitral regurgitation, the follow-up monitoring of disease progression, the selection of the optimal timing of surgical intervention and the evaluation of the effect of surgical treatment.
