概述

三尖瓣疾病是一种心脏瓣膜病(瓣膜性心脏病)。两个右心腔(右心室和右心房)之间的瓣膜不能正常工作。因此,心脏必须更努力地工作,将血液输送至肺部和身体其他部位。

三尖瓣疾病常伴有其他心脏瓣膜问题。

三尖瓣疾病的症状和治疗方法因具体瓣膜状况而异。治疗方法可能包括监测、用药、瓣膜修复或瓣膜置换术。

类型

存在几种类型的三尖瓣疾病,包括:

  • 三尖瓣反流三尖瓣未正确闭合。这会导致血液回流进入右上腔室(右心房)。
  • 三尖瓣狭窄。瓣膜变窄或堵塞,导致血液更难从右上心腔(右心房)流向右下心腔(右心室)。
  • 三尖瓣闭锁如果出生时就存在这种病症(先天性心脏缺陷),患者将不会形成三尖瓣。右心腔之间的血流将被一个实心片状组织阻塞。
  • 三尖瓣下移畸形这是一种出生时即存在的罕见心脏问题(先天性心脏缺陷)。三尖瓣处于错误的位置,瓣膜形状畸形。血液可能通过瓣膜渗回(三尖瓣反流)。
