The secundum type of atrial septal defect (ASD) is recognized as the most common form of ASD encountered in clinical practice. This defect occurs in the area of the fossa ovalis, which is a thin part of the atrial septum where there is typically a natural opening during fetal life that usually closes after birth.

This type of ASD allows for shunting of blood from the left atrium to the right atrium due to the higher pressure in the left atrium, leading to an increase in right atrial and right ventricular volume. The prominence of the secundum type is significant in that it represents a major portion of all congenital heart defects, making awareness of its characteristics essential for diagnosis and management.

The other features mentioned are not associated with secundum ASD. For instance, hypoplastic left heart syndrome is a distinct and serious congenital heart defect that does not relate to the presence of a secundum ASD. Additionally, secundum ASDs are typically located centrally in the atrial septum, away from the tricuspid valve, which is more consequential in the context of other types of ASD. Lastly, while this type of defect can lead to right heart volume overload and potentially contribute to right heart failure over time, it
