Parasternal long axis view in normal echocardiogram

RV FW: Right ventricular free wall; RV: Right ventricle; IVS: Interventricular septum; Ao: Aorta; RCC: Right coronary cusp of aortic valve; NCC: Non coronary cusp of aortic valve; LVOT: Left ventricular outflow tract; AML: Anterior mitral leaflet; PML: Posterior mitral leaflet; LA: Left atrium; LV: Left ventricle; LV PW: Left ventricular free wall. Parasternal long axis view is often the first view taken during two dimensional echocardiography. It is taken from the left parasternal region with the ultrasound beam in plan parallel to the base-apex (long axis) of the heart. If the transducer is turned ninety degrees from this view, the parasternal short axis view will be obtained. The most superficial part of the heart imaged in this view is the pericardium covering the right ventricular free wall. M-Mode measurements of the left ventricle, aorta, left atrium and the mitral valve are usually guided from this view. This view is good for visualization of mitral and aortic regurgitations on color Doppler imaging. Doming of mitral and aortic valves in stenotic conditions will be seen well in this view. A perimembranous ventricular septal defect can be seen in this view just below the aortic valve. Aortic over-ride in Fallot’s tetralogy is well seen in parasternal long axis  (PLAX) view. Prolapse of the aortic and mitral valve can be seen in PLAX view. Asymmetric septal hypertrophy and systolic anterior motion of the mitral valve in hypertrophic obstructive cardiomyopathy are...
