wherein the artificial heart valve (1) comprises a ring (3), a first valve leaflet (5), and a second valve leaflet (7),
wherein the first valve leaflet (5) and the second valve leaflet (7) are connected to the ring (3) at an upper part of the artificial heart valve (1),
wherein the first valve leaflet (5) and the second valve leaflet (7) are connected at a lower part junction (9) existing at a lower part of the artificial heart valve (1), and
wherein the first valve leaflet (5) and the second valve leaflet (7) have, at a lower part of the ring (3), a portion which become narrower in width toward the bottom thereof, and have a shape which is the narrowest in width at a lower end thereof,
