The case of a patient who survived strut fracture and embolization of a Björk-Shiley mitral prosthetic disc is presented. Prompt surgical treatment was directly responsible for survival. In addition, computerized axial tomography of the abdomen aided in localizing and retrieving the embolized disc, which was lodged at the origin of the superior mesenteric artery. A review of similar case reports from the literature supports our conclusions that the development of acute heart failure and absent or muffled prosthetic heart sounds in a patient with a Björk-Shiley prosthetic heart valve inserted prior to 1978 should raise the possibility of valve dysfunction and lead to early reoperation.
本文介绍了一例Björk-Shiley二尖瓣人工瓣膜瓣盘骨折并栓塞后存活的患者。及时的手术治疗是其存活的直接原因。此外，腹部计算机断层扫描有助于定位和取出栓塞的瓣盘，该瓣盘嵌顿于肠系膜上动脉起始处。对文献中类似病例报告的回顾支持我们的结论，即1978年以前植入Björk-Shiley人工心脏瓣膜的患者出现急性心力衰竭以及人工心脏瓣膜音消失或减弱，应提高瓣膜功能障碍的可能性并导致早期再次手术。
