Content

The double outlet of the right ventricle of the heart disease is the origin of the aorta and pulmonary artery in the right ventricle, or a large artery and another major artery originate from the right ventricle. Ventricular septal defect is usually higher than the aortic diameter, only 10% cases of ventricular septal defect of the small aperture opening ratio of aorta, ventricular septal defect is about 60% below the aortic valve, 30% located below the pulmonary valve, a few cases of ventricular septal defect position in the middle part of the aorta and pulmonary artery in the lower part of the lower part of the opening, and large artery very few cases of ventricular septal defect in ventricular septal opening far away.

There are many methods for the right ventricle outlet of chd. According to the relationship between the anatomic position of the interventricular septal defect and the trunk of the artery, the double outlet of the right ventricle can be classified as follows:

Double outlet of right ventricle

1 aortic valve defect with pulmonary stenosis, without pulmonary stenosis;

2 pulmonary valve ventricular septal defect with pulmonary stenosis without pulmonary stenosis;

3 ventricular septal defect associated with the opening of the two major arteries, with pulmonary stenosis, without pulmonary stenosis;

4 had no ventricular septal defect associated with the opening of the two major arteries;

Double outlet right ventricle

1 aortic septal defect, without or with pulmonary stenosis;

2 pulmonary septal defect with or without pulmonary stenosis;

3 of the ventricular septal defects associated with the opening of the two major arteries, without or with pulmonary stenosis;

4 had no ventricular septal defect associated with the opening of the two major arteries;

Other complex types

Total anomalous pulmonary venous connection, complete common atrioventricular canal, mitral atresia or stenosis, aortic stenosis or hypoplasia.

There are different classifications of right ventricular double outlet, which play an important role in the future treatment.
