孤立性心室肌致密化不全超声诊断

目的　研究超声心动图 (U CG)诊断孤立性心室肌致密化不全 (Isolated noncom paction of the ventricular my-ocardium INVM)的价值。方法　仪器采用 ATL 30 0 0 ,HP5 5 0 0或 ACUSON 12 8XP10 C彩色超声仪 ,探头 2～4 MHz。结果　 U CG特点心室内均出现大量突出的肌小梁及深陷的小梁隐窝 ,进一步测量小梁隐窝深度计算 X/Y比值 ,比值从二尖瓣水平到心尖水平逐渐减小。结论　 UCG可特异性诊断 INVM。

Diagnosis of Isolated noncompaction of the ventricular myocardium with Echocardiography

Objective To study the valueof diagnosis of INVM with echocardiography. Methods ATL3000,HP5500,ACUSON 128XP 10C color ultrasound system with 2～4MHz. Results Echocardiography features were as follows: numerous prominent ventricular trabeculations and deep intertrabecular recesses were presented in ventricle. The depths of the intertrabecular recesses were assessed by a quantitative echocardiography X to Y ratio. The ratio were smaller gradually from mitral valve level to apex. Conclusion UCG is promising first line diagnostic tool for INVM.
