Answer

The subcostal view is preferred at initial screening for mechanical activity and pericardial fluid and for gross assessment of global and regional abnormalities. To obtain a subcostal view, place the transducer on the left subcostal margin with the beam aimed at the left shoulder.

The parasternal view allows visualization of the aortic valve, proximal ascending aorta, and posterior pericardium and permits determination of left ventricular size. It is particularly helpful when the subcostal view is difficult to obtain. To obtain a parasternal view, place the transducer in the left parasternal area between the second and fourth intercostal spaces. The plane of the beam is parallel to a line drawn from the right shoulder to the left hip.
