The tricuspid annulus is an oval semi-circular ring that is modeled after the tricuspid annulus in the human body. The tricuspid valve is located between the right atrium and the right ventricle, and mainly maintains the flow of blood from the atrium to the ventricle. The tricuspid annulus, which is commonly seen in clinical practice, is an elliptical semi-circular ring made of titanium alloy or biomaterials, which is placed into the heart during the operation, and has a certain degree of elasticity to adapt to atrioventricular motion of the heart. The tricuspid ring is placed in the heart and closed with sutures, which reduces the stress on the suture ring, thus minimizing tearing or damage to the valve itself. The tricuspid ring is not absorbed after placement and is generally effective in the long term. If a tricuspid annuloplasty ring is needed, it is recommended to go to the hospital in time and follow the doctor’s instructions to avoid adverse consequences.
