Diseases of other endocardial structures

Diseases of tricuspid valve
- The backflow of blood from the right ventricle into the right atrium, owning to imperfect functioning/insufficiency of the tricuspid valve.
- Incomplete closure of the tricuspid valve, resulting in tricuspid regurgitation; it is usually secondary to systolic overload in the right ventricle.
- Narrowing or stricture of the tricuspid orifice of the heart.
