The Left Anterior Oblique or LAO is obtained with the patients LEFT chest wall against the  sensor or film cassette.  This view is often used in angiography to better visualize the arch of the aorta, and its major branches to the head and upper extremities (arms).  Easy to remember: LAO - "Lay Aorta Open" (so you can look into the arch).
