彩色多普勒与其它检查方法对心尖肥厚型心肌病诊断价值的比较

目的 :探讨CDFI对AHCM的诊断价值。材料和方法 :对经ECG、MRI、CIN和EMB检查确诊的AHCM的CD FI特点与诊断及鉴别诊断方法进行分析、讨论。结果 :分别由上述检测技术提示或证实的 2 1例AHCM患者均显示乳头肌以下心室游离壁 /室间隔不同程度的增厚。当厚度 >1 5cm以上者 ,心室收缩时 ,室腔区可消失。 2 1例中有 2例合并有右室心尖肥厚。结论 :CDFI为AHCM最理想的检测方法。如结合以上其它检查 ,特别是ECG提示 ,则可避免假阴性的出现 ,进一步提高准确性

The Value of Color Doppler Flow Imaging in Apical Hypertrophic Cardiomyopathy:Comparing with Other Diagnostic Methods

Purpose:To evaluate color Doppler flow imaging (CDFI)in diagnosing apical hypertrophy cardiomyopathy (AHCM)and to compare it with other diagnostic methods. Materials and Methods:21 patients with AHCM diagnosed by ECG, MRI, CIN, and EMB underwent CDFI. Results:In all 21 patients, free wall of left ventricle and/or inter ventricular septum below the level of pilliary muscle were thicker than normal. In cases with wall thickness >1 5cm, the cardiac chamber was so small that it was hardly detectable in systolic phase. 2 cases had apical hypertrophy involving right ventricle. Conclusion:CDFI is valuable in the diagnosis of AHCM. Combined with other diagnostic methods, especially with ECG, the diagnostic sensitivity of AHCM could be improved.
