| tricuspid | 1. Having three cusps, or points; tricuspidate; as, a tricuspid molar. 2. <anatomy> Of or pertaining to the tricuspid valves; as, tricuspid obstruction. <anatomy> Tricuspid valve, the valve, consisting of three triangular membranous flaps, at the opening of the right auricle into the right ventricle in the heart of most mammals; sometimes called the tricuspid valves, each flap being regarded as a valve. Origin: L. Tricuspis, -idis; tri- (see Tri-) + cuspis a point: cf. F. Tricuspide. Source: Websters Dictionary (01 Mar 1998) |
| tricuspid area | The region of the chest wall over the lower part of the body of the sternum, where the sounds produced at the tricuspid valve are heard most distinctly. (05 Mar 2000) |
| tricuspid atresia | Absence of the orifice between the right atrium and ventricle, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (hypertrophy, left ventricular) because the right ventricle is absent or not functional. (12 Dec 1998) |
| tricuspid incompetence | Defective closure of the tricuspid valve permitting regurgitation into the right atrium during systole. (05 Mar 2000) |
| tricuspid insufficiency | See: valvular insufficiency. (05 Mar 2000) |
| tricuspid murmur | A murmur produced at the tricuspid orifice, either obstructive or regurgitant. (05 Mar 2000) |
| tricuspid orifice | An atrioventricular opening which leads from the right atrium into the right ventricle of the heart. Synonym: ostium atrioventriculare dextrum, ostium venosum cordis. (05 Mar 2000) |
| tricuspid stenosis | Pathologic narrowing of the orifice of the tricuspid valve. (05 Mar 2000) |
| tricuspid tooth | A tooth having a crown with three cusps. (05 Mar 2000) |
| uterine prolapse | The abnormal downward displacement of the uterus from its normal anatomic position within the pelvis. Higher grade prolapse can result in protrusion of the uterus from the vaginal canal. (27 Sep 1997) |
| abnormal cleavage of cardiac valve | Congenital malformation of a valve leaflet with a defect extending from the free margin. (05 Mar 2000) |
| Amussat's valve | A series of crescentic folds of mucous membrane in the upper part of the cystic duct, arranged in a somewhat spiral manner. Synonym: plica spiralis ductus cystici, Amussat's valve, Heister's valve, spiral valve of cystic duct, valvula spiralis. (05 Mar 2000) |
| anterior cusp of atrioventricular valve | The anterior leaflet or valvule of either the tricuspid or mitral valves. Synonym: cuspis anterior valvae atrioventricularis dextrae/sinistrae. (05 Mar 2000) |
| anterior urethral valve | A crescentic horizontal fold in the proximal spongy urethra. (05 Mar 2000) |
