Suprasternal view

Suprasternal view allows for visualization of the aortic arch, measurement of the ascending, descending and transverse arch. It is also the opportunity to evaluate for coarctation, hypoplastic arch or presence of a posterior shelf leading to obstruction. PW Doppler may be obtained in the pre and post-ductal aorta, as well as in the ascending aorta. The angulation is optimal for assessing aortic stenosis CW-Doppler.

Pre-ductal descending aorta indicating forward flow in systole and diastole.

Post-ductal descending aorta PW-Doppler indicating reversal of flow during diastole (left to right ductus arteriosus leading to diastolic steal effect).

It is important to evaluate the bifurcation of the first vessel (brachiocephalic) to ensure a bifurcation towards the right side - left sided arch. In the presence of a right-sided arch, one may need to further delineate if there is presence of a vascular ring.

This view is also useful to assess SVC flow and presence of catheter's position in the upper limb entering the right atrium via the SVC.
