What is an atrioventricular canal defect?

An atrioventricular septal defect (also known as an atrioventricular canal defect) is a congenital heart condition, which means it’s present at birth. It describes several heart problems, including a hole in the wall (septum) at the center of your heart, as well as problems with the way your heart’s valves work.

The condition forces your heart to work too hard to pump blood. It also allows blood to flow in the wrong direction. It can lead to a range of health conditions, including congestive heart failure.

Atrioventricular septal defects are very common in children with Down syndrome.
