Abstract

胎儿先天性心脏病左室流出道切面教学标本制备方法,选用心脏发育畸形的引产胎儿,将其防腐处理后制作出游离的心脏标本,心脏的左室流出道切面以肺动脉圆锥作为断面的起始点,使切面的横轴与心脏的长轴平行,向上经升主动脉至上腔静脉,向下经前室间沟直达心尖部来作一切面。所得到的左室流出道切面标本各部结构完整齐全,不损伤心脏内部的微小结构,与真实活体内形状相同,能很好的满足医学教学与实践等需要的优点,适于学校、医院或医学科研机构。
The invention relates to a method for preparing a teaching specimen of a left ventricular outflow tract view of a fetus suffered from a congenital heart disease. In the method, a free heart specimen is prepared after a selected artificially-labored fetus having a malformed heart is antiseptically treated; and in the left ventricular outflow tract view, the horizontal axis of the view is parallel to the long axis of the heart by taking a pulmonary conus as a start point of a cross section, the cross section is up to a superior vena cava through aorta ascendens and down to the apex of the heart through an anterior interventricular groove. The obtained apical four-chamber view specimen has the advantages of integrated and complete structures of all parts, no damage to microstructures in the heart, the same shape as that in a real living body, and capability of meeting the requirements of medical teaching and practice and the like, and is suitable for schools, hospitals or medical research institutes.
