The Björk-Shiley tilting disc prosthesis demonstrated acceptable early mortality and good functional recovery with low rates of complications.
Indicates favorable early results with Björk-Shiley prosthesis; leaves open need for larger prospective comparisons.
The operation on and subsequent course of 88 patients with valve replacements using Björk-Shiley tilting disc prostheses has been reviewed in terms of mortality, clinical results, and valve function. The follow-up period varied between 6 months and 2 years. The hospital mortality was 17% and late mortality 8%. Of those who left hospital, 75% returned to full normal activity and required less (or no) drug therapy other than maintenance anticoagulation. There was one transient embolic episode. Significant intravascular haemolysis does not occur with this prosthesis.
