The Björk-Shiley pyrolytic carbon disc prosthesis demonstrated satisfactory long-term performance in the tricuspid position with no thromboembolic or thrombotic complications in a small cohort.
Small series suggests acceptable tricuspid performance without thrombosis; leaves open need for larger comparative trials before wider use.
Ten-year experience of tricuspid valve replacement with the Björk-Shiley pyrolytic carbon disc is reported. Of the twelve patients, one died in association with the operation, due to tracheo-oesophageal fistula. There were four late deaths, two from unknown causes, one during re-replacement of mitral valve and one from carcinoma of the urinary bladder. No patient had thromboembolism, valve thrombosis or subacute infective endocarditis. From the analysis of the hospital records and follow-up data it is concluded that the Björk-Shiley pyrolytic carbon disc prosthesis is a satisfactory substitute for the tricuspid valve.
