Defect in the pulmonary artery wall

Normally, the aorta and pulmonary artery are connected to each other is not. Defect aortolegochnoy septum is the presence of openings between the ascending aorta and pulmonary artery. It is formed as a result of impaired formation between aortolegochnoy septum.

This is a rare malformation. The frequency of less than one percent of all congenital heart defects. The hole can be in any part of the septum. Its value is usually from 2 to 30 mm. Since the pressure in the aorta more pressure in the pulmonary artery, resets the arterial blood from the aorta into the pulmonary artery. Which leads to an increase in pressure in the pulmonary vessels and increase blood volume in the pulmonary circulation. The extent of these changes depends on the size of the hole.

Complaints of patients with non-specific. Shortness of breath, fatigue with a little exercise. A child may lag behind in physical development. Frequent pneumonia and other lung diseases.

This defect is diagnosed with:

auscultation - auscultated sistolodiastolichesky noise, ie during both phases of contraction and relaxation of cardiac muscle

on the electrocardiogram - reveal an increase in both ventricles of the heart
X-ray examination - are changes in the lungs and strengthen the pulsation of the aorta.

Treatment septum defect aorto pulmonary only operative. Performed surgery in the early stages in the first year of life, as this vice early pathological changes occur in the lungs. The operation consists in tying the hole between the aorta and pulmonary artery, or if the hole is placed a large patch. The operation is performed under extracorporeal circulation.
