Abstract
A prosthetic heart valve of the bileaflet type is characterized in particular by having leaflets in confronting relation to one another which are guided along opposite sides of the leaflets for accurate controlled swinging movement between open and closed positions in such a way that the guiding portions do not interfere with or restrict in any way the opening size of the valve but permit effective washing action as the blood flows therethrough.
