Description

60歳男性.大動脈弁狭窄のため,88年11月大動脈弁置換術(Medtronic-Hall弁:23mm)を施行.89年11月より胸痛が出現,90年5月心筋梗塞を発症し,当科に紹介された.心音図上,閉鎖クリックの異常に幅広い分裂と著明な出現遅延を認め,頸動脈波は切痕の異常な低位を示した.超音波ドプラ検査にて,拡張早期に限局する特異な大動脈弁逆流(AR)がみられ,大動脈造影でも同時相にSellers II度のARを認めた.同年9月12日再手術を施行,人工弁の左室側弁輪部にフィブリン血栓の付着を認めた.血栓を除去し,弁装着方向を回転させたところ,上記の諸種異常所見は消失した.術前に認めた,大動脈弁逆流を含む諸種異常所見は,弁閉鎖過程の異常を反映したものと考えられた.
