Ventricular septal defect
Ventricular septal defect
The septum between the left and right ventricles of the heart is called the ventricular septum. An intact ventricular septum prevents blood flow between the left and right ventricles. Ventricular septal defect (VSD) is a condition where there is a hole in the ventricular septum, causing blood from the left and right ventricles to mix, leading to a series of problems. It is the most common congenital heart disease. The symptoms of VSD vary. If the defect is small, there are usually no obvious symptoms. If the defect is large, it can manifest as shortness of breath and fatigue after activity, and in severe cases, it can lead to growth and developmental delays.
