50例左室假腱索二维超声心动图分析

目的就左室假腱索患者的临床资料进行分析,并对鉴别诊断等问题提出初步看法。方法应用二维超声心动图在1026例中检出50例左室假腱索。使用PHILIPUSHD7超声诊断仪,多切面检查心脏。检查标准为:不论任何一个切面,凡有跨越左室腔的线样回声,且与左房室瓣不相连者即可确定。结果左室长轴切面发现率最高,最易发现室间隔至前或侧壁之假腱索;二尖瓣及乳头肌水平短轴切面次之,较易发现室间隔至前或侧壁之假腱索;心尖四腔切面发现率少,易发现近心尖部细小的或网络样线样回声。结论以往曾认为左室假腱索是无临床意义的解剖学变异,现在我们认为它可能是某些心前区杂音或心率失常的重要原因。

Objective Left ventricular false tendons in patients with clinical data analysis, and the differential diagnosis of such problem offers initial view.Methods Using two-dimensional ultrasound heartbeat graph in 1026 cases were detected in 50 cases of left ventricular false tendons. The use of PHILIPUS HD7 ultrasonic diagnostic instrument, multisection examination of the heart. Inspection standard： regardless of any one section, all across the left ventricular cavity linear echo, and with the left atrioventricular valve connected to determine. Results The left ventrieular longitudinal found was the highest, most easily found septal to front or sMe wall of false tendons; mitral and papillary level short axis view time, easier to find the septal to front or side wall of the false discovery rate; apical four chamber view, easy to be found near apex small or network sample line echo. Conclusion The previous left ventricular false tendons are of no clinical significance of anatomical variation, we now think it is possible that some precordial murmur or arrhythmia important reason.
