超声心动图诊断心肌致密化不全8例报告

Echocardiography Diagnosis of Noncompaction of Ventricular Myocardium Report of 8 Cases

目的探讨心肌致密化不全(NVM)的超声心动图图像特征,评价超声心动图对该病的诊断价值。方法采用彩色多普勒超声诊断仪(探头频率2～4MHz)对8例NVM患者进行检查。结果8例超声均见心室内有许多粗乱突起的肌小梁和深陷的小梁间隐窝,彩色血流显示隐窝内血流与心室腔交通,心肌收缩力减弱。其中病变累及左室型5例,双室型l例,右室型2例。结论NVM具有典型声像图表现;超声心动图在NVM无症状阶段即可发现病变,是诊断NVM的最可靠且简便的检查手段。

Objective To explore the echocardiography characteristics of noncompaction of ventricular myocardium（NVM）,and to assess its value in the diagnosis of NVM.Methods Color doppler ultrasound system with 2～4 MHz transducers was used in 8 patients with NVM.ResultsIn all 8 patients,multiple trabeculations and deep intertrabecular recesses communicating with the ventricular cavity were found by color doppler imaging,the ability of myocardium contraction decended were found as well.These patients including 5 cases left ventricle type,1 case double ventricles type,2 cases right ventricle type.Conclusion NVM had typical echocardiography characteristics.NVM can be found on echocardiography even before patients’ symptoms appear,so echocardiography is a kind of reliable and convenient method for diagnosing NVM.
