What is the medical term used for the condition that results in a heart murmur due to atrial septal defect?

The medical term that describes a heart murmur resulting from an atrial septal defect is best categorized as an acyanotic heart defect. An atrial septal defect is a congenital condition involving a hole in the wall (septum) that separates the two upper chambers of the heart (the atria). This defect allows oxygen-rich blood from the left atrium to flow into the right atrium, leading to increased blood flow to the right side of the heart and the lungs without causing a significant reduction in oxygen saturation in the arterial blood.

In acyanotic heart defects, such as atrial septal defects, the blood flow is typically left-to-right, which does not result in cyanosis—a bluish discoloration due to inadequate oxygenation. This condition can lead to various physiological changes and heart murmurs, but cyanosis does not occur, hence the classification as acyanotic.

The other choices refer to different conditions. Acute rheumatic fever is a complication following streptococcal throat infection that can cause heart valve damage but is not directly related to atrial septal defects. Congestive heart failure is a condition that can arise due to various heart defects but does not directly denote the murmur caused by an atrial
