  • 初回僧帽弁形成術後の systolic anterior motion (SAM) に対し後尖連続縫合による height reduction を追加した1例

    在國寺 健太, 澤崎 優, 泊 史朗 日本心臓血管外科学会雑誌 46 (6), 288-291, 2017

    ...僧帽弁形成術におけるsystolic anterior motion(SAM)は,いまだに経験される合併症で対応に時として難渋する.今回初回形成術後SAMを呈し,再形成術を行った症例を経験したため報告する.症例は56歳女性.腱索断裂による後尖逸脱,僧帽弁閉鎖不全症に対し僧帽弁形成術を施行した.右側左房切開でアプローチすると,P3の腱索断裂を認め,P3弁尖は27 mmと高く広範囲が逸脱していたため,P3のhourglass-shaped...
