2.3.1 Parasternal window Longaxis views (PLAX) 123 Sonography
The basic concept of echocardiography was first demonstrated by Lazzaro Spallanzani in the 18 century when he described the reflected echoes of inaudible sound. [1] Hertz and Edler reported the first use of ultrasound in the cardiac evaluation and continuous monitoring of heart movements in 1954. [2]
Parasternal long axis view of a representative echocardiographic image
Transthoracic echocardiography (TTE) is the primary initial imaging modality in cardiac imaging. Advantages include portability, safety, availability, and ability to assess the morphology and physiology of the heart in a noninvasive manner.
Parasternal long axis view of the transthoracic echocardiography which
Parasternal long axis view is often the first view obtained during an echocardiographic study. It is used to guide M-Mode echocardiography for left ventricular measurements. Initially the parasternal long axis view is obtained.

The parasternal long-axis view (PLAX) is located on the left side of the sternum. It provides imaging planes of the long axis of the heart. Figure 2 illustrates the position of the transducer, the orientation of the index marker and the scanning plane through the heart.

sional (2D) imaging (Figure 5). Alternatively, the left parasternal view is also used for measuring RV wall thickness. Thickness > 5 mm indicates RV hypertrophy (RVH) and may suggest RV pressure overload in the absence of other pathologies. IVC DIMENSION. The subcostal view permits imaging and measure-

Parasternal Long-Axis View. A pericardial effusion is seen as an anechoic (black) region between the hyperechoic (bright) pericardium and the walls of the heart. The image demonstrates a small pericardial effusion, while the illustration demonstrates the location of a larger (circumferential) effusion.

The segments are studied in six views: the parasternal long axis, the parasternal short axis at the levels of the mitral valve, papillary muscles, and apex, apical four chambers, apical two chambers. The scoring system is based on if the wall motion is normal, hypokinetic, akinetic, or dyskinetic. Based on the wall motion, a score of 1 to 4 is.

Figure 1. Two-dimensional echocardiogram. This view is called parasternal long axis view (PLAX). Structures that are closest to the transducer are placed at the top of the image. RV = right ventricle. LV = left ventricle. LA = left atrium. Ao = aorta.
Parasternal longaxis view demonstrating pericardial effusion and
The Parasternal Long Axis View is often abbreviated as PSLA or PLAX. It is usually the first cardiac ultrasound view obtained and will give you an immediate assessment of the general condition of the heart including ejection fraction and overall left and right ventricular sizes.

Parasternal long axis (PLAX) view is one of the easiest views to obtain and answers most of the questions encountered in day-to-day nephrology practice. The sonographic anatomy, image acquisition and key pathologies seen in this view are discussed below. How is the exam performed? The transducer or the probe:

Normal parasternal long axis view; Parasternal short axis view: This view is a cross sectional view of the left and right sides of the heart. These can be "sliced" at various levels between the base and the apex. By fanning the probe towards the right shoulder, one can visualize the aortic valve in cross section.
