Which view is commonly used in echocardiography to visualize the aortic arch?

The suprasternal notch view is commonly used in echocardiography to visualize the aortic arch because it offers a direct line of sight to this area by utilizing the anatomical position of the suprasternal notch—located at the top of the sternum. This view allows the sonographer to assess the arch's structure and the great vessels that branch off of it, such as the brachiocephalic artery, left common carotid artery, and left subclavian artery.

This view is particularly valuable for identifying abnormalities such as coarctation of the aorta, aneurysms, or various congenital heart defects involving the great vessels. In contrast, other echocardiographic views like the subcostal view, apical four-chamber view, and parasternal long axis view are primarily focused on different cardiac structures and chambers, making them less ideal for evaluating the aortic arch specifically.
