Examples of central and eccentric aortic regurgitation (AR) jets recorded by TEE. The components of AR by color Doppler are highlighted by arrows in the example of central AR: flow convergence, vena contracta (VC) and jet width in the left ventricular outflow tract. Note the smaller size and location of the vena contracta compared to the jet width in the LV outflow tract. The eccentric AR jet is directed towards the mitral valve (arrow) with a prominent flow convergence. Jet width in the left ventricular outflow in this eccentric jet cannot be used for evaluation of AR severity. LA = left atrium; LV = left ventricle.
