We report a successful elective re-AVR and MVR 10 years after AVR with aortic root enlargement and OMC. The patient was a 41-year-old woman. The diagnosis of thrombosed Björk-Shiley (B-S) valve was first suspected by transtelephone PCG monitoring and reconfirmed by the frequency analysis of prosthetic valve sounds and the aortography preoperatively. The thrombosis was 15 x 8 x 6.5 mm in size and located at the minor orifice of B-S valve, extending to the strut. The transtelephone PCG was useful in analyzing prosthetic valve sounds for patients especially living away from the hospital.
我们报告了1例在进行主动脉瓣置换术（AVR）并伴有主动脉根部扩大和人工机械瓣（OMC）植入10年后成功进行择期再次AVR和二尖瓣置换术（MVR）的病例。患者为一名41岁女性。经电话经胸心脏超声（PCG）监测首次怀疑血栓形成的Björk-Shiley（B-S）瓣，并通过术前人工瓣膜声音频率分析和主动脉造影再次确认。血栓大小为15×8×6.5mm，位于B-S瓣的小孔处，延伸至支柱。电话经胸心脏超声对于分析人工瓣膜声音很有用，尤其是对于居住在远离医院地方的患者。
