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.
