Ventricular septal defect (VSD)
A ventricular septal defect means that there is a hole between the lower pumping chambers (ventricles) in the heart.
The hole allows blood to flow from the left side of the heart to the right, increasing the pressure of the blood travelling to the lungs and making the heart work harder.
A VSD is a form of congenital heart disease – a term used to describe a problem with the heart’s structure and function due to abnormal development before birth.
