【摘要】 目的 分析了解心肌致密化不全(noncompaction of ventricular myocardtium，NVM)的超声心动图诊断价值。 方法 对4例心肌致密化不全患者采用HP5500彩色超声诊断仪，进行常规检查，重点观察左室长轴、短轴、四腔心切面。 结果 4例患者中均可见左室腔内未致密化的粗大肌小梁及隐窝，4例都未合并其他先天性心脏病，且均为左心室型。2例出现明显心功能不全，1例出现心律失常，另1例无明显症状。结论 应用超声心动图诊断心肌致密化不全是目前临床的最佳选择，它简便，经济，无创，结果可靠。

    【Abstract】 Objective To explore the clinical value of echocardiographic diagnosis of noncompaction of ventricular myocardium.Methods HP5500 color ultrasound system was used for 4 patients examination.Emphasis was put in observing left ventricular long-axis、short-axis and four chamber longitudinal section.Results In all the 4 patients,numerous prominent ventricular trabeculations and deep intertrabecular recesses were presented in echocardiogram.None of 4 cases complicated with other congenital heart disease.In all cases left heart was involved.In 2 cases showed cardiac insufficiency very clearly,1 case showed arrhythmia and 1 case showed nothing obviously.Conclusion The echocardiographic diagnosis is proved to be an optimal approach to the diagnosis of noncompaction of ventricular myocardium,which appears to be more economical,non- invasive and easy to perform. ......
