Combined mitral and aortic valve replacement with the Börk-Shiley prosthesis
Insights
Combined mitral and aortic valve replacement using the Björk-Shiley prosthesis showed a 9.5% mortality rate. While morbidity was elevated, most patients remained asymptomatic post-surgery.
Area of Science:
- Cardiovascular Surgery
- Prosthetic Heart Valves
- Cardiac Valve Disease
Background:
- Combined mitral and aortic valve disease often requires complex surgical intervention.
- The Björk-Shiley tilting-disc valve prosthesis is a potential option for these complex cases.
Purpose of the Study:
- To evaluate the outcomes of combined mitral and aortic valve replacement using the Björk-Shiley prosthesis.
- To assess mortality, morbidity, and long-term patient status after this procedure.
Main Methods:
- Retrospective analysis of 42 patients undergoing combined mitral and aortic valve replacement.
- Utilized the Björk-Shiley tilting-disc valve prosthesis.
- Follow-up included assessment of mortality, morbidity, embolism, hemorrhage, and valvular function.
Main Results:
- Hospital and late mortality rates were both 9.5%.
- Elevated morbidity was observed, with one case of severe hemorrhage.
- No embolic events occurred; only one patient had minor valvular dysfunction.
- 75.7% of patients were asymptomatic at a mean follow-up of 21.1 months.
Conclusions:
- The Björk-Shiley prosthesis demonstrates acceptable mortality and low embolic risk in combined valve replacement.
- Its low profile and minimal gradient are advantageous for multiple valve procedures.
- While morbidity requires attention, favorable long-term asymptomatic rates support its use.
Abstract:
Combined mitral and aortic valve replacement with the BJORK-Shiley tilting-disc valve prosthesis was performed in 42 patients. Hospital and late mortality rates were both at the 9.5% level. No correlation was seen between mortality and combination of concomitant valve lesions. Morbidity was elevated. No episodes of embolism were observed after surgery, although one patient died of severe haemorrhage. Only one patient showed valvular dysfunction (grade 2/4 leakage), but did not require reoperation. Postoperatively, 75.7% of the patients were asymptomatic for a mean follow-up period of 21.1 months. The Björk-Shiley prosthesis offers a small gradient associated with a low profile, which constitute important advantages in multiple valve replacement.
