先天性肺动脉瓣畸形及肺动脉狭窄或闭锁,是复杂的先天性心脏病常见的伴发畸形,孤立出现者少见,分类困难,文献报道亦不一致,尚无合理的标准。我们通过130例先天性心脏病尸检标本,仔细观察分析后,以肺动脉瓣有无为主要标准提出以下分类;1.有瓣类:可分为闭锁型、狭窄型和无狭窄型,后两者肺动脉瓣叶数目多少不拘,瓣叶、瓣环和瓣孔均较正常为小者为狭窄型,否则为无狭窄型;如肺动脉瓣膜存在,交界融合,瓣孔闭锁,而与之相连的漏斗部却清
Congenital pulmonary valve malformations and pulmonary stenosis or atresia, is a common concomitant congenital heart disease complicated, rare in isolation, classification difficulties, the literature is also inconsistent, there is no reasonable standard. We passed the 130 cases of congenital heart disease autopsy specimens, after careful observation and analysis, with or without pulmonary valve as the main criteria for the following classification; 1. Valvular categories: can be divided into atresia type, narrow and no stenosis, the latter two pulmonary The number of leaflets is not much, the valve leaflets, valve annulus and valve holes are smaller than the normal for the narrow type, otherwise no stenosis; such as the presence of pulmonary valve, the junction of fusion, valve hole atresia, while connected with the funnel Department clear
