Clinical results with the use of the SJM Biocor stentless aortic valve at 7 years

In the normal aortic valve, resulting blood flow eddies promote proper valve closure and lessen leaflet impact during opening. An ideal aortic valve substitute should therefore incorporate the aortic sinuses to achieve this physiological haemodynamic performance. Homografts and the stentless aortic valve are the present substitutes that respect this important principle.
