Supports Björk-Shiley preference in aortic valve replacement; extends RCT evidence of hemodynamic superiority versus Lillehei-Kaster.
Does the Björk-Shiley aortic disc valve prosthesis improve haemodynamics compared to the Lillehei-Kaster valve in patients undergoing aortic valve replacement?
The Björk-Shiley aortic disc valve provides superior haemodynamics compared to the Lillehei-Kaster valve, particularly in small sizes.
Levang et al. (1979) studied this question.
