請教懂醫學術語的網友：

請問下麵兩句話是什麽意思？ 大致的意思？ 謝謝了！ 我隻閱讀了該研究的結論部分， 關於老年病人接受心髒瓣膜手術的研究。 文章發表於2017 年。

  1. “New York Heart Association class was significantly improved (P<0.001).”
  2. “After the procedure, TR was reduced by at least 1 grade in 91% of the patients, thereof 4% that were reduced from massive to severe.”

文章的來源和鏈接如下： 先謝謝啦！
