Transthoracic echocardiographic parasternal view transducer position and standard images

(A) Orientation of the probe indicator.
(B) Direction of the ultrasound beam on the heart.
(C-H) Identification of the heart chambers and echocardiographic appearance on parasternal-short-axis view.
(C-D) Aortic valve level.
(E-F) Mitral valve level.
(G-H) Mid-papillary level. This transition of views is achieved while the sonographer makes a tilting ("fanning") movement of the probe. The aortic level view is obtained with superior "fanning" of the probe and mitral level and mid-papillary view with inferior direction "fanning" of the probe.
