右心室条束的形态观测及其临床意义

Morphological Study of Right Ventricular Bands and Its Clinical Significance

目的:为右心室条束的超声心动图诊断提供形态学基础。方法:采用50例成人心脏标本,观察右心室条束的出现率、附着点和形态,并对其长度和直径进行测量。结果:①有右心室条束34例,出现率为68％;其中,有2条或多条束者16例(47.07％)。右心室条束总计66条。②右心室条束分布于右心室的流入道,且多附着于室间隔与后乳头肌、乳头肌与乳头肌之间。③右心室条束的长度和直径分别为13.79±6.58mm和0.82±0.72mm。结论:右心室条束为正常解剖结构,但其异常可能引起临床症状。

Objective:The purpose of this study is to provide morphological data of right ventricular bands for echocardiography diagnosis. Methods: Prevalenos, attachments, morphological features, lengths and diameters of right ventricular hands were observed and measured on 50 hearts of adult cadavers. Results: (1) right ventricular bauds were observed in 34 specimens, and the prevalence was 68%. of the 34 specimens containing right ventricular hands. 16(47.07%) exhibited 2 or mure,such that the total number of right ventricular hands identified was 66.(2)Right ventricular bands were in the inflow tract of the right ventricle,and they mostly attached the interventricular septum and the posterior papillary muscle, the papillary muscle and the papillary muscle, (3)The lengths and diameters of right ventricular bands were 13.79±6.58mm and 0.82 ± 0.72mm respectively. Conclusion: Right ventricular hands an: normal human anatomical structures,but their abnormality would possibly result in clinical symptoms.
