';Ventricular Septal Defect Overview


Ventricular septal defect is a hole in the wall between the right and left ventricles of the heart. This abnormality usually develops before birth and is found most often in infants.





The ventricles are the 2 lower chambers of the heart. The wall between them is called the septum. A hole in the septum is called a septal defect.





If the hole is located between the upper chambers or atria, it is called an atrial septal defect.';
