ASD stands for?

• A. Atrial Septal Defect
• B. Atrial Septum Defect
• C. Aortic Septal Defect
• D. Atrium Septal Dysfunction

Answer: (A)

The main idea here is knowing what ASD stands for in congenital heart terminology. ASD stands for atrial septal defect, a hole in the interatrial septum—the wall that separates the right and left atria. Because the left atrium usually has higher pressure than the right, blood tends to shunt from left to right through that opening, increasing right-heart and pulmonary blood flow. The term uses atrial to relate to the heart’s atria, septal to describe the septum, and defect to indicate a hole or opening. This is the standard wording for the condition, whereas options like Atrial Septum Defect, Aortic Septal Defect, or Atrium Septal Dysfunction are not the conventional terms. In practice, small ASDs may close on their own in children, while larger ones can require intervention to prevent long-term effects from volume overload and potential embolic risk. A fixed, widely split S2 with a possible systolic murmur can be an associated finding.
