Atrioventricular valve repair with artificial chordal replacement has been widely used for congenital and acquired mitral valve abnormalities, but not for tricuspid valve abnormalities. A case is presented of dysplastic tricuspid valve that was successfully repaired using artificial chordae. A 2-year-old female presented with poor weight gain. Echocardiography revealed severe tricuspid regurgitation due to dysplastic tricuspid valve, poor coaptation by prolapse of the anterior leaflet, and tethering of the septal leaflet by short chordae. The prolapsed anterior leaflet was repaired with three pairs of 6-0 expanded polytetrafluoroethylene sutures. The short chordae of the septal leaflet were detached, and the septal and posterior leaflets were sutured together. Trivial tricuspid regurgitation was noted postoperatively. There was no tricuspid regurgitation during the follow up period of three years. The present case provides further evidence that artificial chordal replacement is a useful technique even for small children with congenitally abnormal tricuspid valves.

D002815 Chordae Tendineae The tendinous cords that connect each cusp of the two atrioventricular HEART VALVES to appropriate PAPILLARY MUSCLES in the HEART VENTRICLES, preventing the valves from reversing themselves when the ventricles contract. Tendineae, Chordae
D003490 Cyanosis A bluish or purplish discoloration of the skin and mucous membranes due to an increase in the amount of deoxygenated hemoglobin in the blood or a structural defect in the hemoglobin molecule. Cyanoses
D005260 Female Females
D005500 Follow-Up Studies Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D014261 Tricuspid Valve The valve consisting of three cusps situated between the right atrium and right ventricle of the heart. Tricuspid Valves,Valve, Tricuspid,Valves, Tricuspid
D014262 Tricuspid Valve Insufficiency Backflow of blood from the RIGHT VENTRICLE into the RIGHT ATRIUM due to imperfect closure of the TRICUSPID VALVE. Tricuspid Incompetence,Tricuspid Regurgitation,Tricuspid Valve Incompetence,Tricuspid Valve Regurgitation,Incompetence, Tricuspid,Incompetence, Tricuspid Valve,Insufficiency, Tricuspid Valve,Regurgitation, Tricuspid,Regurgitation, Tricuspid Valve,Valve Incompetence, Tricuspid,Valve Insufficiency, Tricuspid,Valve Regurgitation, Tricuspid
D014263 Tricuspid Valve Prolapse Abnormal protrusion of one or more of the leaflets of TRICUSPID VALVE into the RIGHT ATRIUM during SYSTOLE. This allows the backflow of blood into right atrium leading to TRICUSPID VALVE INSUFFICIENCY; SYSTOLIC MURMURS. Its most common cause is not primary valve abnormality but rather the dilation of the RIGHT VENTRICLE and the tricuspid annulus.
