Acquired tricuspid regurgitation

Tricuspid regurgitation can be relative and organic. In the relative case, the valve itself has no lesion, but the right ventricle is hypertrophic, and the atrioventricular ring expands accordingly, resulting in poor tricuspid leaflet involution and incomplete closure. Patients with mitral stenosis or regurgitation in severe rheumatic heart disease are often accompanied by relative tricuspid regurgitation. Organic tricuspid regurgitation is a sequelae of rheumatic fever, which is rare in clinic. Most of them are accompanied by mitral and aortic valve diseases at the same time. The pathological changes were thickening and contracting of valve fibers, shortening of tendons and enlargement of valve rings. The valves could not be fully aligned during cardiac contraction. Often combined with the fusion of valve junction, so it also has stenosis.
