Having passed the 30th anniversary of the first implantation of a Björk-Shiley convexo-concave tilting mechanical valve, recognition of the life-threatening complication of strut fracture is not widespread. The authors report the case of a 48-year-old man with acute-onset chest pain and dyspnea found to have strut fracture and disk embolization of a 26-year-old Björk-Shiley prosthetic aortic valve. The value of echocardiography in the diagnosis of this condition is discussed.
在经历了首例 Björk-Shiley 凸凹倾碟式机械瓣膜植入 30 周年之后，人们对支架断裂这一危及生命的并发症的认识还并不广泛。作者报告了一例 48 岁男性患者，突发胸痛和呼吸困难，发现为 26 岁 Björk-Shiley 人工主动脉瓣的支架断裂和瓣叶栓塞。讨论了超声心动图在这种情况下的诊断价值。
