摘要

二尖瓣(僧帽瓣)逆流是常見之心臟瓣膜疾病，而二尖瓣脫垂是其主要成因，因先天瓣膜缺陷不良或某些疾病影響而造成瓣膜結構缺陷，進而影響血液動力學之正常運作，出現心悸、焦慮等症狀。若飛行員有此疾患，當面臨低壓、大G等高空特殊環境時，會加重循環系統之缺陷效應，進而影響操作航空器之穩定性、飛航安全與人員戰力。鑒於當前我國國軍教範並未對此病作明確之評估考量，本文參照美國空軍及海軍之最新教範，將此疾病之標準檢查如心臟超音波結果與症狀嚴重程度進行分類，並執行航醫應為的評估建議與相關醫療處置，以祈對我國國軍之飛行安全與效率有顯著助益。

Mitral regurgitation is a very common valvular disease, also one of the primary clinical and aeromedical concerns for mitral valve prolapse. Such organic defects result in hemodynamic instability, and cause cardiac arrhythmias, palpitations and anxiety, et cetera. Mitral valve prolapse diagnosed in aircrew might reduce +Gz tolerance and impact flight performance, and endanger flight safety. As ROC waiver currently include guideline for the aeromedical disposition of mitral valve prolapse, we introduced diagnostic standard and severity grading of mitral valve prolapse, referring from the latest USAF and US navy waiver guide. Suggestions for flight surgeons were proposed and aeromedical disposition for this group of pilots were discussed.
