超声在小儿心肌致密化不全的诊断价值

The value of ultrasonography in the diagnosis of pyknosis insufficiency of ventricular myocardium

目的:探讨超声诊断小儿心肌致密化不全的价值。方法:采用ACUSON S2000超声诊断仪,4V1c探头,频率3~4.5 MHz。观察左室长轴及短轴切面,二腔心切面,四腔心切面,观察心外膜下致密层心肌及心内膜下致密化不全心肌。结果:所有6例均可见心室内致密化不全的肌小梁及其间深陷的隐窝,6例均为左室型,均有心功能不全,4例有心律失常。结论:超声是诊断小儿心肌致密化不全的最佳选择。

Objective:To explore the the value of ultrasonography in the diagnosis of pyknosis insufficiency of ventricular myocardium.Methods:Using the Siemens production company ACUSON S2000 ultrasound diagnostic apparatus,4V1 c probe,the frequency of 3 to 4.5 MHz,we observed the left ventricular long axis and short axis view,two chamber view,four chamber view,observed subendocardial myocardial and endocardial dense layer of pyknosis insufficiency of myocardial.Results:There are intraventricular non compaction trabecular muscles and deep recess in all the 6 cases,6 cases were all left ventricular type.They all had heart failure.4 cases had arrhythmia.Conclusion:Ultrasound is the best choice for the diagnosis of left ventricular noncompaction.
