Thrombotic catastrophe in the patient with multiple Björk-Shiley prostheses
Insights
Thrombosis of Björk-Shiley mechanical heart valves is a known complication. Patients with multiple Björk-Shiley prostheses face greater diagnostic and therapeutic challenges, with a 26.8% cumulative incidence of thrombosis at six years.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
- Prosthetic Heart Valves
Background:
- Thrombosis associated with Björk-Shiley prostheses is a long-standing clinical concern.
- The use of multiple prosthetic valves presents unique management challenges.
Purpose of the Study:
- To evaluate the incidence and management of thrombosis in patients with Björk-Shiley prostheses.
- To specifically assess complications in patients with multiple Björk-Shiley valve implants.
Main Methods:
- Retrospective review of 172 patients who received one or more Björk-Shiley valves.
- Analysis of patient data from January 1975 to July 1980 at the University of Kentucky Medical Center.
Main Results:
- Patients with multiple Björk-Shiley prostheses experienced increased diagnostic and therapeutic difficulties.
- The cumulative incidence of thrombosis was 26.8% at six years in patients with multiple prostheses.
Conclusions:
- Multiple Björk-Shiley prostheses are associated with a significantly higher risk of thrombosis.
- Long-term use of multiple Björk-Shiley prostheses is not recommended due to these complications.
Abstract:
Thrombosis of the Björk-Shiley prosthesis has been a recognized problem for many years. Review of 172 patients at the University of Kentucky Medical Center who had one or more Björk-Shiley valves inserted between January, 1975, and July, 1980, revealed special problems in those patients with multiple prostheses. Diagnosis and therapy prove more difficult, and the cumulative incidence of thrombosis in the patients with multiple prostheses is 26.8% at six years. Projected long-term use of multiple Björk-Shiley prostheses is discouraged.
