Smith, Paul A. Tricuspid regurgitation TR is the most common lesion of the tricuspid valve TV. Mild TR is common and usually is benign. However, moderate or severe TR can lead to irreversible myocardial damage and adverse outcomes. Despite these findings, few patients with significant TR undergo surgery. The treatment of functional secondary TR in particular remains controversial because of high rates of residual or recurrent TR and poor outcomes following surgical intervention.

Blood that flows between different chambers of your heart must pass through a heart valve. These valves open up enough so that blood can flow through. They then close, keeping blood from flowing backward. The tricuspid valve separates the right lower heart chamber the right ventricle from the right upper heart chamber right atrium. Tricuspid regurgitation is a disorder in which this valve does not close tight enough.

In order to understand tricuspid regurgitation, it helps to understand the basic anatomy of your heart. Your heart is divided into four sections called chambers. The upper chambers are the left atrium and right atrium, and the lower chambers are the left ventricle and right ventricle. The left and right sides of the heart are separated by a wall of muscle called the septum.
