摘      要：Background and Aim: It has been widely acknowledged, that tricuspid valve repair is not solely done, and itis done along with accompanying repair procedures. Tricuspid valve disease has a directimpact on the severity of the disease. Identifying the risk of the disease or severity of valvelesions which is related to the outcome of the patient, and increase in life span has animportant role in surgical practice. Moreover, location and size of the lesion plays a key rolein the management of the valve to attain the best surgical approach. Several literature hasshown, that patients undergoing concomitant surgical procedures has a less impact ontricuspid valve than mitral and aortic valves, also described as a forgotten valve.[14,15,16]Logically, the patients become asymptomatic during the early onset of disease as the severityof the disease progress symptoms will appear, and the doctors also anonymous to its signsand symptoms so, this disease is hidden until the disease approaches in its severe stages. Andthese diseases also get less importance or attention than left sided heart diseases. Diseaseclassification is depends on the pathology of the valve. In heart, tricuspid valve plays a keyrole in distributing the deoxygenated blood to lungs. The tricuspid valve has three leaflets orcusps which access the regulation of blood flow and maintain the way of systemic *** tricuspid valve damages, the deoxygenated blood regressing back to the right atrium whichalters in pressure and influences pulmonary circulation and systemic circulation. Not onlywith this, tricuspid valve shows major consequences while the patient is having left-sidedheart disorders. The orifice of tricuspid valve is rough and triangular, and is also larger thanthe mitral valve. Chordae tendineae originates from papillary muscles, which attaches to thecusps of the valve. During systole, right ventricle contracts, and the tricuspid valve closes,papillary muscles come in action to pull the chordae
