左心房分隔

定义

一种先天性心脏畸形，其中有一个隔断将左心房分为接受部分或全部肺静脉的后上腔和与左心耳和房室交界区（通常是二尖瓣）相通的前下腔。 附加信息：在区分 "分割左心房 "和 "先天性瓣上或瓣内二尖瓣环 "时，后者的前下腔仅包含二尖瓣口。

A congenital cardiac malformation in which there is a partition that divides the left atrium into a posterosuperior chamber that receives some or all of the pulmonary veins and an antero-inferior chamber that communicates with the left atrial appendage and atrioventricular junction (usually the mitral valve). Additional information: in differentiating 'Divided left atrium' from 'Congenital supravalvar or intravalvar mitral ring', in the latter, the antero-inferior compartment contains only the mitral valvar orifice.
