  • Echocardiographic Assessment: High Parasternal View Pulmonary Artery and Sweep to Aortic Arch
    • 2D:  2D of this view between the ascending aorta and pulmonary arteries confirms the presence of an AP window. 
    • Color Doppler: Short sweep from this view between the ascending aorta and pulmonary arteries with color confirms shunting across the AP window. 
    • Still: Measurements of the large AP window between the ascending aorta and MPA.

    • 3rd or 4th intercostal space (slide upward 1-2 rib spaces and slightly more medial to obtain this modified view)
