【摘要】 目的：评价房室瓣腱索在房室瓣病变的诊断和治疗中的临床价值。方法：我们应用动态三维重建技术，研究了３３例房室瓣病变患者的腱索，其中男性１８例，女性１５例，年龄１４～５６岁，全部病例经手术及／或心导管证实，图像采集使用ＨＰＳＯＮＯＳ２５００超声心动图仪（配有３．７／５．０ＭＨｚ的多平面经食道探头），三维重建采用ＴＯＭＴＥＣＥＣＨＯＳＣＡＮ系统，将采集的图像提取并重建，从房室的侧面观察房室瓣腱索及瓣膜情况。结果：本组瓣膜病患者，有两组腱索增粗并钙化者及腱索稀疏与断裂者均行瓣膜置换术，仅单组腱索增粗者行瓣膜球囊扩张术，两组腱索增粗而无钙化者行瓣膜闭式分离术，动态三维重建技术展示了二维显像所不能获得的房室瓣腱索的立体图像。结论：动态三维重建房室瓣腱索能全面评价房室瓣病变，在瓣膜病的诊断与治疗中有重要意义。更多还原

【Abstract】 Objective:This study was sought ot compare the ultrasonic backscatter parameters of myocardium between patients of hypertension and hypertrophic cardiomyopathy,and try to find the way distinguishing these two diseases.Methods:Myocardial ultrasonic backscatter parameters of 37 hypertension(HT)patients,15 hypertrophic cardiomyopathy (HCM) patients with hypertrophic interventricular septum and 40 normal were measured.Results:Interventricular septum IB% and TG CVIB of HCM patients were significantly increased than those of HT patients and normal control( P <0 01).Conclusion:Ultrasonic backscatter parameters are useful in discrimination between hypertrophic cardiomyopathy and hypertension.更多还原
