Septal defects refer to congenital abnormalities that involve openings or holes in the septum, the wall that separates the left and right chambers of the heart. These defects can occur in the atrial septum (known as Atrial Septal Defects or ASDs) or the ventricular septum (known as Ventricular Septal Defects or VSDs). Such defects can lead to abnormal blood flow between the chambers, resulting in various cardiac complications.
