The ventricular septal defect is the most common congenital heart defect in childhood (30%). Most patients have an isolated VSD, however a VSD also occurs in combination with other defects like Tetralogy of Fallot, which will be discussed elsewhere. About five percent of all patients with a VSD have a chromosomal abnormality, including trisomy 13, 18 and 21. Due to a high rate of spontaneous closure (50%) VSD is less seen in adulthood. | The ventricular septal defect is the most common congenital heart defect in childhood (30%).

There are three main anatomic components of the interventricular septum ( | There are three main anatomic components of the interventricular septum (Figure 3); the septum of the atrioventricular canal (1), the muscular septum (2), the parietal band or distal conal septum (3). VSDs may occur at various locations in any of the three components. The location of the defect is not of particular interest when taking the characteristics of the intracardiac shunt in account. However it is important in terms of the frequency of involvement of the atrioventricular valves and the rate of spontaneous closure and additionally the relation to the AV pathway when considering surgical correction. | ||
