Description

Using the same probe position used to obtain the long axis parasternal view, the probe is rotated clockwise by 90 degrees with the marker now facing the left shoulder. This brings into view the aorta and its cusps centrally, with the right heart structures wrapping around it. This view is used to assess the tri-leaflet aortic valve, high perimembranous ventricular septal defects, the coronary arteries, and the right ventricular inflow and outflow tracts. Colour Doppler assessment of the aorta in short axis will further delineate the coronaries, assess the presence of aortic incompetence, and detect perimembranous VSDs.
