Description
カウンターパルセーションは、心臓の機械的補助の周知の形態である。毎年世界中で100,000人以上の患者に使用されており、心機能不全が短期である多くの患者が救われうる。これらの患者のほとんどすべては、現在では動脈内バルーンポンプ(IABP)を用いた治療を受けており、この動脈内バルーンポンプは、患者の下行大動脈に置かれたカテーテルに取り付けられたバルーンから構成され、心臓の機能を向上させるために、バルーンが膨らんだりしぼんだりする。バルーンカテーテルは、通常、鼠径部の動脈に挿入され、このカテーテルは、患者のベッドのわきに置かれた制御装置につながれている。制御装置は、細いカテーテルを通して、ヘリウムのような軽い気体を、バルーンに入れたり出したりする。バルーンは、心臓が脈打つのにあわせて非常に早く空になり、大動脈内の圧力を下げ、心臓が血液を押し出すのを容易にする。心臓が弛緩するとバルーンはふくらみ、血液が心臓の動脈及び体の他の部分を通って押し出される。心臓の負荷を減らすことと、心臓への血流を増大させることの組み合わせは、心機能に関して非常に有益な効果を有する。
