Japanese Journal of Cardiovascular Surgery | 2002

Hiromi Yano; Naoki Konagai; Mitsunori Maeda; Masaharu Misaka; Taisuke Matsumaru; Tatsuhiko Kudou; Shin Ishimaru

症例は59歳男性.15年来閉塞性肥大型心筋症(HOCM)で,βブロッカーを投与中であった.本年6月より突然の心不全の進行を認め,経食道心エコーにて僧帽弁腱索断裂と診断した.まず内科的治療にて症状を改善させたのちに,開心術とした.僧帽弁前尖と後尖に腱索断裂を認めたため,人工弁置換術を施行し,腱索の病理組織診断は粘液変性であった.術後経過は良好であり,また心エコーでは,左室流出路圧較差は術前55mmHgから術後0mmHgとなり,狭窄は消失した.HOCMに腱索断裂を合併すると僧帽弁逆流による心不全の急性増悪をきたすため,経食道心エコーなどによる早期診断と時期を逸することなく外科的治療を行うことが必要と考えられた.
