Abstract

Percutaneous transvenous mitral commissurotomy using the Inoue technique was performed in a 59-year-old female with mitral stenosis and a severely calcified mitral leaflets. Although not entrapped in the subvalvular apparatus, the balloon catheter was deviated away from the mitral orifice-apex axis of the left ventricle during the inflation of the proximal balloon, which plucked and severed the chordae tendineae of the posterior mitral leaflet and resulted in severe mitral regurgitation.

摘要

采用井上技术对一名59岁二尖瓣狭窄且二尖瓣叶严重钙化的女性患者进行经皮经静脉二尖瓣交界切开术。尽管球囊导管未陷入瓣下装置，但在近端球囊充盈时，其偏离了左心室二尖瓣口-心尖轴线，拉扯并切断了二尖瓣后叶的腱索，导致严重二尖瓣反流。
