Why the study?
Does the Lillehei-Kaster pivoting disc valve compared to the Bjork-Shiley tilting disc valve affect the incidence and severity of intravascular haemolysis in patients after single aortic valve replacement?
Population
64 patients one year after single aortic valve replacement
Comparison
Lillehei-Kaster pivoting disc valve vs Bjork-Shiley (Delrin) tilting disc valve
Design
RCT, randomized series
Follow-up
one year

Both valves induce only mild, insignificant haemolysis post-AVR; confirms their equivalence with minimal clinical impact.
Does the Lillehei-Kaster pivoting disc valve compared to the Bjork-Shiley tilting disc valve affect the incidence and severity of intravascular haemolysis in patients after single aortic valve replacement?
Both Lillehei-Kaster and Bjork-Shiley disc valves cause mild, clinically insignificant intravascular haemolysis one year after aortic valve replacement.
