Tricuspid insufficiency

Due to congenital or acquired factors that cause tricuspid valve disease or tricuspid annulus dilation, the tricuspid valve is not fully closed during the systole. The disease is both functional and organic. The former is mostly secondary to lesions that cause right ventricular dilatation, and the incidence is quite high, such as primary pulmonary hypertension, mitral valve disease, pulmonary valve or funnel stenosis, and right ventricle. Myocardial infarction and so on. The latter can be congenital abnormalities such as Ebstein's malformation and common atrioventricular passages, or acquired diseases such as rheumatic inflammation, coronary artery disease caused by tricuspid papillary muscle insufficiency, trauma, and infective endocarditis. The prognosis of the disease depends on the nature of the underlying cause and the severity of heart failure. Prognosis caused by primary pulmonary hypertension and chronic pulmonary heart disease is often worse than that caused by mitral valve disease or atrial septal defect. . Medical treatment can alleviate the symptoms, and surgery can cure it.
