what does it mean aortic valve is trileaflet
All the valves are trileaflet, with the exemption of the mitral valve, which has two leaflets. All four cardiac valves are surrounded by fibrous tissue forming partial or complete valvular rings, or annuli. These annuli join the fibrous skeleton of the heart to support and anchor the valvular structures.The aortic valve is situated between the left ventricular outflow tract and the ascending aorta.he normal human heart contains four valves that regulate blood flow into and out of the heart. The aortic and pulmonic valves are identified as the semilunar valves, whereas the tricuspid and mitral valves are referred to as the atrioventricular valves.
