The suprasternal window is imaged with the patient in the supine position, with his or her chin slightly tilted toward the ceiling. The transducer index mark is pointed directly at 12 o’clock toward the patient’s neck. The suprasternal notch view allows for visualization of the ascending aorta, aortic arch, and descending aorta in long axis. The great vessels can also be seen coming off of the aortic arch. This view can be used to evaluate color flow Doppler of the aortic arch for any signs of turbulent flow. The arch can also be imaged in a short axis view, and evaluated for any significant dilation, aneurysms or aortic dissections. If Doppler angles allow, spectral Doppler can be performed through the long axis of the ascending or descending aorta to identify any stenosis or diastolic flow reversal significant for severe aortic insufficiency.
