Combined mitral and aortic valve replacement with the Börk-Shiley prosthesis

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.
