Tricuspid Annulus: Definition, Uses, and Clinical Overview
The Tricuspid Annulus is the fibrous and muscular “ring” that forms the base of the tricuspid valve. It sits between the right atrium (upper right chamber) and right ventricle (lower right chamber). Clinicians reference it in heart imaging, valve disease evaluation, and planning valve repair procedures. Its size and shape can change with the heartbeat and with certain heart conditions.
