Why the study?
Does the Björk-Shiley tilting disc valve reduce intravascular haemolysis compared to the Lillehei-Kaster pivoting disc valve in patients undergoing combined mitral and aortic valve replacement?

35 patients examined 12-24 months after combined mitral and aortic valve replacements
Comparison
Björk-Shiley tilting disc valve vs Lillehei-Kaster pivoting disc valve (n=16)
Design
RCT, randomized
Follow-up
12-24 months

Supports preferring Björk-Shiley over Lillehei-Kaster to limit hemolysis after double valve replacement; confirms prosthesis-specific differences in hemolytic burden.
Does the Björk-Shiley tilting disc valve reduce intravascular haemolysis compared to the Lillehei-Kaster pivoting disc valve in patients undergoing combined mitral and aortic valve replacement?
The Björk-Shiley tilting disc valve is associated with significantly less intravascular haemolysis (lower LDH) than the Lillehei-Kaster pivoting disc valve after combined mitral and aortic valve replacement, though both are clinically benign.
