The tricuspid valve (also known as the right atrioventricular valve) is on the right side of the heart, between the right atrium and the right ventricle. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Medical Subject Headings ( MeSH) is a huge Controlled vocabulary (or metadata system for the purpose of indexing journal articles and books Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group The right atrium (in older texts termed the "right auricle" is one of four chambers (two atria and two ventricles in the Human The right ventricle is one of four chambers (two atria and two ventricles in the Human Heart. The normal tricuspid valve usually has three leaflets and three papillary muscles. In Anatomy, the papillary muscles of the Heart serve to limit the movements of the mitral and Tricuspid valves These muscles contract to tighten They are connected to the papillary muscles by the chordae tendineae, which lay in the right ventricle. The chordae tendineae, or heart strings, are cord-like Tendons that connect the Papillary muscles to the Tricuspid valve and the Tricuspid valves may also occur with two or four leaflets, and the number may change during life.

Pathology

Tricuspid regurgitation is not uncommon in the tricuspid valve. Regurgitation is Blood flow in the opposite direction from normal as the backward flowing of blood into the Heart or between heart chambers It is a common valve to be infected (endocarditis) in IV drug users. Endocarditis is an Inflammation of the inner layer of the Heart, the Endocardium. [2][3] Although it is not a common site of endocarditis, patients with a small VSD usually develop endocarditis of the tricuspid valve.

The tricuspid valve can be affected by rheumatic fever which can cause tricuspid stenosis or tricuspid insufficiency (also called tricuspid regurgitation). Rheumatic fever is an Autoimmune inflammatory Disease which may develop two to three weeks after a Group A streptococcal infection (such as Tricuspid valve stenosis is a Valvular heart disease which results in the narrowing of the orifice of the Tricuspid valve of the Heart. Tricuspid insufficiency, a Valvular heart disease also called Tricuspid regurgitation, refers to the failure of the heart's Tricuspid valve to close properly Some patients are born with congenital abnormalities of the tricuspid valve. A congenital disorder is a disease or disorder that is present at birth Congenital apical displacement of the tricuspid valve is called Ebstein's anomaly and typically causes significant tricuspid regurgitation. Ebstein's anomaly is a Congenital heart defect in which the opening of the Tricuspid valve is displaced towards the apex of the Right ventricle of the Tricuspid insufficiency, a Valvular heart disease also called Tricuspid regurgitation, refers to the failure of the heart's Tricuspid valve to close properly

The first endovascular tricuspid valve implant was performed by physicians at the Cleveland Clinic. The Cleveland Clinic (formally known as the Cleveland Clinic Foundation) is a multispecialty academic medical center located in Cleveland, Ohio, [4]
