| tricuspid valve | <anatomy> This heart valve, named for its three cusps (leaflets), divides the right atrium and the right ventricle. When the right atrium contracts blood flows through the tricuspid valve into the right ventricle. On closure, the tricuspid prohibits the backflow of blood into the right atrium. (19 Jan 1998) |
| tricuspid valve insufficiency | Backflow of blood from the right ventricle into the right atrium, owing to imperfect functioning of the tricuspid valve. (12 Dec 1998) |
| tricuspid valve prolapse | Abnormal protrusion of one or more of the leaflets of the tricuspid valve into the right atrium during systole. (12 Dec 1998) |
| tricuspid valve stenosis | The pathologic narrowing of the orifice of the tricuspid valve. (12 Dec 1998) |
