Ventricular septal defect

Ventricular septal defect (VSD) schematic Ventricular septal defect refers to ventricular septal hypoplasia during embryonic development, forming abnormal traffic, and generating left-to-right shunts at the ventricular level. It can exist alone or be a component of some complex cardiac malformation. Ventricular deficiency is the most common congenital heart disease. Ventricular septal defect is about 20% of the total number of congenital heart disease, which can exist alone or coexist with other deformities. Defects range from 0.1 to 3 cm, those in the membrane are larger, and those in the muscle are smaller. The latter is also called Roger's disease. If the defect is less than 0.5cm, the partial flow is small, and there are usually no clinical symptoms. The right ventricle enlarges mainly in the small defect, and the left ventricle enlarges significantly in the large defect.
