Heart chamber wall defect. Artwork of a posterior (from behind) view of a defective heart, sectioned to show the internal anatomy. The defect is a hole in the wall (septum) between the heart's two ventricles, known as an ventricular septal defect (VSD). This results in deoxygenated blood (blue arrow) from the right side of the heart mixing with oxygenated blood (red arrow) from the left side of the heart. This can lead to pulmonary hypertension and breathlessness. VSD is usually a congenital defect, present at birth. It can close and heal without intervention, though in severe cases surgery may be needed to repair the defect.
