Two-dimensional transthoracic echocardiogram (2D TTE) parasternal short axis view of the aortic root

(A) A diagram of the transducer position for obtaining a short axis two dimensional image; the short axis is obtained by a 70° to 110° clockwise rotation of the transducer from the parasternal long axis, with superior and inferior transducer manipulations, and the plane is oriented at the base of the heart (left panel).
(B and C) The parasternal short axis view from a transthoracic echocardiogram shows the noncoronary (NCC), right coronary (RCC), and left coronary (LCC) leaflets of the aortic valve. Also seen are the left atrium (LA), right atrium (RA), tricuspid valve (TV), right ventricle (RV), and pulmonic valve (PV).
