We encountered a case in which prosthetic mitral valve leaflets were jammed by a transmitral balloon catheter during mechanical mitral valve replacement. The catheter, which was inserted in the left ventricle to render the leaflets incompetent during de-airing, forced the leaflets into the closed position. The leaflet edges pinched the catheter lumen and obstructed balloon deflation. Excessive inflation of the balloon and extraction of the catheter before complete deflation of the balloon should be avoided to prevent a potentially serious complication.
我们遇到了一例在机械二尖瓣置换术中人工二尖瓣叶被经二尖瓣球囊导管卡住的病例。在排气过程中，插入左心室以使瓣叶功能不全的导管将瓣叶压至关闭位置。瓣叶边缘夹住导管腔并阻碍球囊放气。应避免在球囊完全放气前过度充盈球囊和拔出导管，以防止潜在的严重并发症。
