Tricuspid regurgitation

Tricuspid regurgitation is called a type of heart disease, which occurs when the tricuspid insufficiency (tricuspid) valve, resulting in  Tricuspid regurgitation - tricuspid insufficiency (tricuspid) valve
 during systole to the backflow of blood from the right ventricle to the atrium.

Tricuspid regurgitation: Causes

Most often, the development of the tricuspid valve regurgitation occurs against a background of heart disease occurring with the expansion of the right ventricle and pulmonary hypertension. Much less this disease arises against bacterial endocarditis, rheumatic fever, carcinoid syndrome, Marfan syndrome. Tricuspid valve can be congenital disorders, or develop as a result of long-term use of certain medications (phentermine, fenfluramine, ergotamine).

Symptoms

If minor defects leaflets of the tricuspid valve (tricuspid regurgitation 1 degree) disease usually does not manifest itself and is considered a benign condition, the treatment is not carried out. Only a small proportion of patients have throbbing neck veins caused by increased pressure in them.

In severe tricuspid valve regurgitation observed a pronounced swelling of the jugular veins. A hand in the right jugular vein can feel her trembling. A significant valve insufficiency may lead to dysfunction of the right ventricle, the emergence of atrial flutter or atrial fibrillation, heart failure formation.

Tricuspid regurgitation: Diagnosis

The correct diagnosis when tricuspid regurgitation, as well as to determine the extent of the disease, it is possible on the basis of Doppler echocardiography. When tricuspid regurgitation 1 degree of regurgitation from the right ventricle back into the right atrium is barely noticeable. Tricuspid regurgitation is characterized by 2 degrees reverse current of blood is no more than 2, 0 cm from the tricuspid valve. In the third power failure regurgitation than 2, 0 cm, while in the fourth - the distributed throughout the volume of the right atrium.

As additional methods of research performed an electrocardiogram and chest X-rays. An electrocardiogram often reveal signs of right ventricular hypertrophy. X-rays when tricuspid regurgitation 1 degree of change is usually not detected. When tricuspid regurgitation grade 2 and above revealed enlarged shadow of the superior vena cava and right atrium, and in some cases, the presence of pleural effusion.

Heart catheterization  For the diagnosis of tricuspid regurgitation performed an electrocardiogram and chest X-rays
 as a diagnostic method for tricuspid regurgitation is rarely carried out.

Treatment for tricuspid regurgitation

Partly tricuspid valve regurgitation is well tolerated by human beings and does not require treatment. Therapy is usually assigned when tricuspid regurgitation 2 - 4 degrees. First of all, it is aimed at addressing the causes that led to the development of the tricuspid valve (treatment of rheumatism, septic endocarditis, etc.). In addition, the conduct and treatment of complications caused by tricuspid regurgitation - heart failure, arrhythmias.

In the absence of effect of conservative treatment carried out, as well as the further progression of the valve disease, surgery is indicated - prosthetics, plastic or tricuspid valve anuloplastika.

By anuloplastike usually resort in cases when the disease develops due dilation (expansion) of the valve ring. Tricuspid valve prosthesis is shown in its failure caused by the Epstein defect or carcinoid syndrome. For pig valve prosthesis used to significantly reduce the likelihood of postoperative thromboembolic complications. As practice shows, pig valve is functioning effectively for over 10 years, before it was replaced.
