右心轴位X线心血管造影解剖

AXIAL ANGIOCARDIOGRAPHIC ANATOMY IN THE RIGHT HEART

本文按照右心常规位和轴位(长轴位、右前斜延长位和四腔心位)造影的投照方位,对55例右心铸型和心脏断面标本进行了心脏形态和轴位造影的对照研究。结合临床应用,从解剖学角度详细描述了与右心造影有关的正常心脏的形态结构,如房室口、三尖瓣、右室流出道、肺动脉瓣及肺动脉主干、房间隔和室间隔等在造影中的形态位置和联系。并对室上嵴,隔缘肉柱和节制带等肌束的形态结构也进行了讨论。联系标本对右心常规位和轴位造影进行了对比,显示了轴位心血管X线造影在显示心脏内部解剖结构和先心病诊断的应用中的优越性。

55 normal adults heart specimens are studied by dissection and casts which are placed in a manner similar to that seen on standard and axial angiocardiographic views (long-axis view,four-chamber view and elongated right anterior oblique view). For clinic application, the normal morphologieal structures of heart which related to angiocardiogram of right heart are studied anatomically, such as, the location and appearaces of right atrioventricular orifice, tricuspid valve, right ventricular outflow tract, pulmonary valve and pulmonary trunk, intcratrial and interventricular septum in angiocardiogram. The constitution and terminology of crista supraventricularis, trabecula septomarginalis and morderator band are discussed. Compared the specimens with the stardard and axial angiocardiography in the diagnoses of congenital heart disease are discussed.
