Haemolysis is common yet rarely clinically relevant after mitral disc valve replacement; this Level 3 cohort comparison leaves open differential long-term effects.
Does the Lillehei-Kaster pivoting disc valve prosthesis compared to the Björk-Shiley tilting disc prosthesis affect the incidence and degree of intravascular haemolysis in patients undergoing mitral valve replacement?
Intravascular haemolysis is common but of little clinical significance after mitral valve replacement with disc prostheses, though it is slightly more pronounced with the Lillehei-Kaster valve compared to the Björk-Shiley valve.
