What Is Tricuspid Regurgitation?

The most common causes are functional insufficiency secondary to right ventricular dilatation and annulus expansion. The primary causes are rheumatic mitral valve disease, congenital heart disease (pulmonary stenosis, Eisenmenger syndrome), and pulmonary heart disease. . The causes of organic tricuspid valve insufficiency are less direct, the most common of which are congenital diseases: tricuspid valve malformation (Ebstein's malformation), and other infective endocarditis and tricuspid prolapse , Carcinoid syndrome, endocardial myocardial fibrosis, etc. Tricuspid valve insufficiency, when the right ventricle contracts, blood returns to the right atrium, and the right atrium rises, leading to systemic congestion and liver enlargement.

1. X-ray inspection

The picture shows the right atrium and right ventricle hypertrophy, the right edge of the heart protruding, and half of the changes caused by other valve lesions.

2. ECG examination

ECG shows atrial hypertrophy, P wave height and width; right bundle branch block or right ventricular hypertrophy, and even myocardial strain. Often have heart

The diagnosis of tricuspid regurgitation should include an understanding of the degree of regurgitation. Typical clinical signs are of value in diagnosing severe tricuspid valve insufficiency. Right ventricular angiography has been used as a means of diagnosing suspicious cases and estimating the degree of reflux. In recent years, ultrasound and Doppler examinations have gradually replaced traumatic examinations.

Drug treatment

(1) Diagnose the primary cause of right heart enlargement and etiological treatment.

(2) Give vasodilators, diuretics, cardiotonic drugs; vasodilators can reduce counterflow.

(3)

For some diseases such as primary pulmonary hypertension, mitral valve disease, pulmonary valve or funnel stenosis, right ventricular myocardial infarction, etc., we should always be vigilant and prevent the occurrence of functional tricuspid regurgitation; and in other diseases such as Ebstein's deformity and common atrioventricular channels in congenital abnormalities, and some acquired diseases such as rheumatic inflammation, coronary artery disease caused by tricuspid papillary muscle dysfunction, trauma and infective endocarditis, etc. Signs of tricuspid insufficiency occur.
