Assessment of left heart volume overloading on visual inspection “eyeballing.” (A) Apical 4 chamber view in 2D showing dilated left side of the heart (dilated left atrium and left ventricle); (B) Mitral regurgitation on color flow mapping as blue jet going back to left atrium (see explanation in text); (C) “Crab view” showing dilated pulmonary veins reflecting increased pulmonary venous return and (D) Dilated left atrium in parasternal short axis view—on visual inspection LA looks almost the double the size of aortic valve (Ao). LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle; Ao, aortic valve; RUPV, right upper pulmonary vein; RLPV, right lower pulmonary vein; LLPV, left lower upper pulmonary vein.
