septal defect a defect in the cardiac septum resulting in an abnormal communication between opposite chambers of the heart. Common types are aortic septal defect, atrial septal defect, and ventricular septal defect. See also congenital heart defect.

septal defect

Etymology: L, saeptum, fence, defectus, failure
a defect in the wall separating the left and right sides of the heart. Depending on the size and the site of the defect, various amounts of oxygenated and deoxygenated blood mix, causing a decrease in the amount of oxygen carried in the blood to the peripheral tissues. The defect is usually congenital. Kinds of septal defects are atrial septal defect and ventricular septal defect.

septal defect

An abnormal opening in the central wall of the heart providing a communication from the right side to the left or vice versa. This is a developmental congenital defect and its significance varies from trivial to grave depending on its position and size. Popularly known as ‘hole in the heart’.
