Tricuspid stenosis

Tricuspid stenosis (stenosis of the right vein opening) in which a defect, tricuspid stenosis due to the opening, there is an obstruction in the movement of blood from the right atrium to the right ventricle.

The cause of

As acquired defects, most frequently caused by rheumatic fever, when associated with mitral stenosis.Less commonly tricuspid stenosis occurs within fibroelastoze endocardium, endomyocardial fibrosis, systemic lupus erythematosus or carcinoid syndrome.

Tricuspid stenosis as a birth defect caused by congenital abnormalities of the tricuspid valve in the heart of the complex malformations.

The clinical picture

The clinical picture depends on the support of the dominant defects (mitral, aortic). If expressed tricuspidal stenosis, dominated fatigue, dyspnea (shortness of breath) and pain in the liver area (venous stasis). Manifested clinical signs are: swollen neck veins, hepatomegaly (enlarged liver), ascites (fluid in the abdomen), peripheral edema (islands).

Diagnosis

It is based on history, clinical presentation, physical examination, ECG, radiology, ultrasound and cardiac catheterization.

Treatment

Diuretics to reduce systemic venous congestion is allowed in isolated and moderately severe forms of the disease. Surgical treatment is considered in the presence of concurrent anomalies and indications for such treatment arises in the case of reduction of tricuspid opening under 2 cm ², or the existence of a pressure gradient of 5 mmHg or more. Surgical treatment involves tricuspid valvuloplasty or valve replacement, and recently he performed balloon dilatation of the tricuspid orifice.
