In the parasternal short axis view, careful examination of the origins of the right and left coronary artery arising from their appropriate sinuses should be demonstrated by 2D imaging AND color Doppler interrogation. Poor visualization of the origin of the left coronary artery or a dilated right coronary artery should make you suspicious for this diagnosis. With color Doppler examination, flow can be seen coursing from the left coronary artery into the pulmonary artery in diastole from this view.
