Ventricular Septal Defect (VSD) is a hole in the wall that separates the two lower chambers of the heart. There are various types of VSD depending on their location. The most common type is perimembranous. The other classifications are muscular, inlet, and infundibular. VSD is also classified as restrictive or nonrestrictive. The problems that might be caused by VSD are higher pressure in the heart and lungs and reduced oxygen to the body. This is caused when the heart and lungs must work harder due to the defect. The high pressure in the blood vessels in the lungs may damage them and also cause congestion. There is a risk of pericarditis due to leaking of the blood out of the hole. It also may make it difficult for children to eat and stunt
