36例心肌致密化不全超声检查及临床特点

摘要

Objective:To analyze ultrasonic and clinical manifestation of noncompaction of the ventricular myocardi‐um (NVM) in order to guide clinical early diagnosis and treatment .Methods :Echocardiographic manifestations of 36 NVM patients were observed .Combined with electrocardiogram (ECG) ,cardiac MRI and coronary angiography (CAG) etc .,clinical manifestations of NVM were comprehensively analyzed .Results:Multiple coarse trabecular muscles and deep crypts among them were founded in heart chamber in all cases .Color Doppler showed that blood flow inside the crypts communicated with blood flow in heart chamber ,there were 33 cases (91.6% ) of left ventri‐cle type and three cases (8.4% ) of right ventricle type .Different types of abnormal ECG existed in all cases and at‐rial fibrillation occupied the largest proportion (50% ,18/36) .Some MRI results were accorded with those of ultra‐sound .In most cases ,CAG didn′t show coronary stenosis .Conclusion : Echocardiography is most convenient and effective examination ,which can provide important basis for diagnosis and treatment of noncompaction of ventricular myocardium .%目的：分析心肌致密化不全的超声及临床表现，以引导临床早期诊断和治疗。方法：观察36例致密化不全心脏的超声心动图表现，结合心电图、心脏磁共振、冠脉造影等检查，综合分析心肌致密化不全的临床表现。结果：所有病例心腔均可见多发粗大肌小梁及其间深陷的隐窝，彩色多普勒可见隐窝内血流与心腔血流相通；呈左心室型者33例（91.6％），右心室型者3例（8.4％）。所有病例存在不同类型异常心电图，其中房颤所占比例最大（50％，18／36）。部分磁共振结果与超声结果吻合。大部分冠脉造影无血管狭窄。结论：超声心动图为最方便、有效的检查方式，可为致密化不全心脏的诊疗提供重要依据。
