目的分析超声心动图在心肌致密化不全(Noncompaction of Ventricular Myocardium NVM)诊断中的应用价值及临床意义。方法彩色多普勒超声心动图对临床心功能不全和心脏扩大的患者进行多切面的探查,总结心肌致密化不全患者的超声心动图特征,分析病变区域的分布特点。结果 15例超声诊断为心肌致密化不全,其中14例为左室受累,1例为左右室均受累。采用jenni等提出的诊断标准:①病变区域心室壁为双层结构,外层较薄为致密层,内层较厚为非致密化心肌,非致密化心肌中间可见深隐窝。②心室收缩末期内层非致密化心肌厚度与外层致密化心肌厚度比值>2.0。③彩色多普勒显示深隐窝内有血流与心室腔相通,患者的超声心动图均显示受累室壁由丰富的肌小梁和深陷的隐窝构成,隐窝内血流与心室腔相通,室间隔及左室前壁无受累。结论心肌致密化不全具有特征性超声心动图表现,是诊断心肌致密化不全可靠首选的方法。

Objective To study the value and clinical significance in the diagnosis of noncompaction of ventricular myocardium(NVM) by using echocardiography.Methods The heart shape,structure and flow of information were obtained by color Doppler echocardiography in patients with clinical heart failure and cardiac enlargement.And echocardiography characteristics in 15 patients with NVM were analyzed.Results 15 cases with NVM were diagnosed by ultrasound,14 out of 15 cases were with left ventricular involvement,and one ...
