A case of malfunctioning Beall prosthetic mitral valve causing severe heart failure is presented. The unusual aspect of this malfunction was the finding of disc dislodgment despite the absence of pathology in the disc itself. The dislodgment was caused by excessive tissue ingrowth around the suture ring. The need for close clinical follow-up of this type of prosthetic valve is emphasized.
本文介绍了一例因Beall人工二尖瓣功能障碍导致严重心力衰竭的病例。该功能障碍的不寻常之处在于，尽管瓣膜盘本身没有病变，但却发现瓣膜盘移位。移位是由缝线环周围过度的组织向内生长引起的。强调了对这类人工瓣膜进行密切临床随访的必要性。
