Ventricular Septal Defect

Ventricular septal defect (VSD) is a congenital vicious collapse of the heart, which is the depletion of part of the interventricular septum. VSD can lead to severe complications and threaten the patient’s life from infancy to old age.

A VSD is a common, congenital defect in the structure of the heart that is characterized by a lack of communication between the left and right ventricles. If the intergastric septum does not close until the 7th to 8th week of embryonic development, the fetus may develop a VSD.

The source of the defect is the cell membrane between the left and right parts of the heart, which develops from the left common arterial duct (LAA), located between the heart and lungs. The LAA is the main source of blood supply to the lungs, and in the embryo its fibrous portion will subsequently form into the middle septum of the pulmonary artery. In congenital heart deafness, the LAA membrane is absent, and the connective tissue is thinned

Interventricular myocardial defect is a congenital heart pathology

**Gastric septal defect (VSD)** is a congenital heart defect in which there is a communication between the right (developing) and left (fundic) ventricles, as a result of which blood is discharged from the right ventricle to the left during systole of the left ventricle. This leads to incomplete filling of the left ventricle and a decrease in its function, i.e. to pulmonary hypertension and cardiomegaly. Some patients may not even notice this abnormality because they have a more severe form of the disease
