Background

The heart valve is a one-way valve structure between an atrium and a ventricle, and ensures that blood flows from the atrium to the ventricle. The normal valve structure includes two portions, a leaflet and an annulus. Valvular disease, typically of the type of valve stenosis/insufficiency, occurs when the anatomy and/or function of the annulus or leaflets is disrupted due to aging, disease, etc. Once a stenosis and/or insufficiency of the valve occurs, normal blood flow is affected and abnormal hemodynamic changes burden the heart, ultimately leading to heart failure. Valvular heart disease seriously affects patient health and quality of life, and therefore, sufficient attention needs to be paid.

Tricuspid valve regurgitation is generally caused by pulmonary hypertension, right ventricular enlargement and tricuspid valve annular dilation, and is clinically commonly represented by the causes of the tricuspid valve regurgitation (left heart failure, pulmonary hypertension and the like), and the symptoms of right heart failure such as tricuspid valve regurgitation, hypodynamia, ascites, edema, liver pain, dyspepsia, anorexia and the like are aggravated. Mild regurgitation of the tricuspid valve has no obvious clinical symptoms, but surgical treatment is required when there is severe regurgitation.

Traditional treatment approaches for mitral and tricuspid valve disease include medications for mild to severe regurgitation, and surgical procedures with corresponding surgical indications. Wherein the surgical method further comprises a valve replacement procedure and a valve repair procedure. In surgical procedures, typical open chest, open heart surgery is too invasive, requiring extracorporeal circulation to be established, with a high incidence of complications and risk of infection. Many patients do not tolerate the enormous surgical risk and can only remain indefinitely at risk for death.
