tricuspid regurgitation
Backward flow through the tricuspid valve causing right heart volume overload. May require surgical repair or replacement.
Full Definition
A condition where the tricuspid valve fails to close completely, allowing blood to flow backward from the right ventricle into the right atrium during systole. This creates volume overload of the right heart and can lead to right heart failure, hepatic congestion, and peripheral edema. Tricuspid regurgitation can be primary (due to valve pathology) or secondary (due to right heart pressure/volume overload). Surgical options include tricuspid valve repair with annuloplasty rings or valve replacement, often performed concomitantly with left-sided valve surgery.
Usage
Usage note: Abbreviate as TR in clinical contexts; distinguish primary from secondary etiology.
