The double discharge of the great vessels from right ventricle


The double discharge of the great vessels from right ventricle

This defect occurs in 1% of children born with congenital heart disease. At the same vice aorta and pulmonary artery away from the right ventricle. In this case there is usually a ventricular septal defect, and it is the only way out of the left ventricle.


The double discharge of the great vessels from the right ventricle is classified into two types depending on the location of ventricular septal defect and the presence and degree of stenosis (narrowing) pulmonary artery. From the same dependent expression of vice and its treatment.

if the ventricular septal defect is under the aorta, the majority of the blood enters the aorta - a type I
Conversely, if the defect is in the pulmonary artery, most of the blood gets into it - type II
if the defect is not accompanied by a narrowing of the pulmonary artery is a type IA or IIA
if there is a narrowing of the pulmonary artery IB or IIB.


In type IA in the first months of life, the child appears shortness of breath, signs of circulatory failure. The child is behind in weight. Auscultated a rough systolic murmur along the left sternal border. An electrocardiogram showed signs of increase of both ventricles. On the x-ray changes in the lungs.

IB type is characterized by shortness of breath, fatigue on exertion, attacks of breathlessness with cyanosis of the skin, the patient may be changes in the fingers on the type of "drumsticks" and nails - "hour-glass." An electrocardiogram showed signs of increased right ventricle.

Type IIA, it is still called the Taussig-Bing anomaly is particularly severe course. The child has low body weight, severe shortness of breath. Developed heart failure is almost impossible to treat. The skin has a slight bluish tint. Auscultated systolic murmur along the left sternal border. On the X-ray arc is defined by the characteristic bulging pulmonary artery, the increased size of the heart.

Type IIB is characterized by severe cyanosis (cyanosis) and resembles the flow of tetralogy of Fallot. The most accurate method for diagnosis of this defect angiocardiography. Research vessels of the heart with the help of contrast agents. It allows you to make an accurate diagnosis and to clarify the place of origin of the vessels.

Treatment.

Today the preferred surgical treatment. Depending on the type of blemish apply different methods of surgical treatment. Radical (with full surgical correction of vice), the operation is performed for children under 4 years. In a later age a complete correction of vice is not possible, therefore, apply partial defect correction methods.
