Thrombotic catastrophe in the patient with multiple Björk-Shiley prostheses.
The Annals of Thoracic Surgery
|March 1, 1983
Summary
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.
