瓣环成形术

瓣环成形术是收紧、重塑或加固心脏瓣膜周围瓣环的手术。可在修复心脏瓣膜的其他治疗中进行。

目的

瓣环成形术可重塑、加固或收紧心脏瓣膜周围受损或发生病变的环状组织。

心脏瓣膜周围的环状组织被称为瓣环。瓣环可能变宽并变形。瓣环变形可能导致瓣叶无法正确打开和关闭。因此,血液可以通过瓣膜向后渗漏,这种状况被称为瓣膜反流。心脏较正常情况增大或心脏瓣膜渗漏可能导致瓣环变形。

可以进行瓣环成形术来修复瓣膜。可以同时进行修复心脏瓣膜的其他手术。

风险

Some possible risks of an annuloplasty are:

  • Bleeding from the surgical cut.
  • Infection.
  • A heart valve that becomes too narrow due to too much tightening during surgery.

To lower risks like these, it's best to see a surgeon who has expertise in doing heart valve repair surgeries.

可能出现的情况

在瓣环成形术中,心脏外科医生会测量瓣膜周围现有瓣环的大小。然后,在现有瓣环上缝一条束带。束带可能为硬性,也可能为柔性。

瓣环成形术可在心内直视手术或微创心脏手术(后者切口较小)期间完成。

研究人员正在研究如何使用细长管以侵入性较小的方式进行瓣环成形术及其他心脏瓣膜治疗。这类方法被称为经导管手术。
