An ostium primum atrial septal defect (ASD) occurs when then atrial septum near the atrioventricular valves has a communication between the two atrium causing a left to right shunt. This rarely ... An atrial septal defect of the secundum type is relatively common and occurs from failure of the septum secundum to develop.

Understanding the Context

This results in a communication between the left and right atrium directly ... An atrial septal defect is the persistence of a hole (the foramen ovale) in the wall (septum) between the right atrium and left atrium of the heart. The foramen ovale usually closes spontaneously ... An atrial septal defect is an opening or hole in the wall that sits between the heart’s two upper chambers.

Key Insights

The heart’s upper chambers are called the right and left atria. Some people refer to atrial ...
