The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, between the right atrium and the right ventricle. The function of the valve is to prevent back flow of blood into the right atrium. 1 Structure.
Insufficiency of the atrioventricular valves causes systolic murmurs: mitral regurgitation(MR) and tricuspid regurgitation(TR). There are four important areas used for listening to heart sounds. These are: Aortic area, Pulmonic area, Tricuspid area, Mitral Area (Apex).
