先天性心脏病是由于胎儿期心脏及大血管发育期间多种因素影响心脏发育而出现障碍并导致的胎儿心脏或血管局部解剖结构以及功能异常,主要发生于胚胎第2~8周,这一期间主要是心脏发育的关键时间,也是心脏房室间隔完全长成时期。先天性心脏病是最常见的出生缺陷之一,可累及心脏的任何部位,影响心脏功能。据估计我国每年出生的先天性心脏病患儿约有15万,未经治疗的患儿很可能在出生后因心脏畸形导致血流动力学异常,进一步出现紫绀,喂养困难,生
Congenital heart disease is due to fetal heart and macrovascular development during the development of many factors that affect the heart to develop obstacles and lead to fetal heart or vascular local anatomy and dysfunction, mainly occurs in embryos from 2 to 8 weeks, during this period Mainly the key time of heart development, but also the heart atrioventricular septum completely into the period. Congenital heart disease is one of the most common birth defects, can affect any part of the heart, affecting heart function.
