In the PLAX view, where is the Coronary Sinus located?

In the Parasternal Long Axis (PLAX) view, the Coronary Sinus is typically found posterior to the Left Atrium, making its location relative to other structures important for identification. It lies in close proximity to the descending aorta, towards the back of the heart. The correct identification as anterior to the descending aorta highlights its position in relation to other prominent structures within the echocardiographic view.

The descending aorta serves as an anatomical landmark that can help visualize and confirm the presence of the Coronary Sinus. In the PLAX view, the left atrium and left ventricle are usually in focus, and the coronary sinus can be assessed for its size and any associated abnormalities. Hence, this choice accurately describes the Coronary Sinus's location, emphasizing the importance of anatomical relationships in echocardiography to understand cardiac structure and function.
