Tilting the probe toward the apex scans the midpapillary plane of the parasternal short axis. This level in the parasternal short axis view shows the left ventricle clearly between the two papillary muscle groups. The left ventricle is bordered by lateral free wall on its right, the muscular interventricular septum on its left, and the inferior free wall at the bottom. The right ventricle is easily visualized and differentiated from the left because it has only one prominent papillary muscle. | |||
This view is ideally used for ventricular wall motion segmental analysis. Thickening and wall motion is visualized in ten segments of the mitral valve and papillary muscle levels. | |||

The base of the heart or the aortic level of the parasternal long axis view can be visualized by tilting the transducer toward the patient’s right shoulder and by rotating it slightly clockwise. The aortic valve is between the left atrium (anterior) and the right ventricle (posterior). The aortic valve and its three leaflets are part of the so-called Y-shape configuration composed of the coronary in the upper region, right coronary in the lower left, and non coronary in the left. The following conditions can be assessed using the aortic level of the parasternal short axis view: aortic root size, structural alterations of the Valsalva sinus, proximal aortic dissection, and presence of anomalies of the aortic valve and abnormalities of the valve leaflets. | The base of the heart or the aortic level of the parasternal long axis view can be visualized by tilting the transducer toward the patient’s right shoulder and by rotating it slightly clockwise.
