2 This document provides updated normal values for all four Cardiac chambers, including three-dimensional echocardiography and myocardial deformation, when possible, on the basis of considerablylarger numbers of normal subjects, compiled from multiple databases. In addition, this document attemptsto eliminate several minor discrepancies that existed between previously published guidelines.

7 Standardization of the methodologyused to quantify Cardiac chambers is maintained by creating anddisseminating official Recommendations , which when followed bypractitioners provides uniformity and facilitates for echocardiographic Chamber quantificationwere last published in 2005 by the American Society ofEchocardiography (ASE) and the European Association ofEchocardiography (renamed the European Association ofCardiovascular Imaging [EACVI]).1,2 Since then, echocardiographic technology has continuedevolving, with two major developments being real-time three-dimensional (3D) echocardiography (3DE) and myocardial defor-mation imaging. The goal of this document is to provide an updateto the previously published guidelines, as well as recommendationsand reference values, while eliminating the minor discrepancies thatexisted between previous guidelines.

8 The normal values in this up-date include 3DE and myocardial deformation, when , compared with the previous guidelines, this update isbased on considerably larger numbers of normal subjects, compiledfrom multiple databases, to improve the reliability of the most issues covered in this document reflect a broadconsensus among the members of the writing group, one importantissue the group debated was partition values for severity of abnormal-ities. Most often, in addition to describing a parameter as normal orabnormal (reference values), clinical echocardiographers qualify thedegree of abnormality with terms such asmildly,moderately, andAbbreviationsAP= AnteroposteriorASE= American Society ofEchocardiographyBSA= Body surface areaCMR= Cardiac magneticresonanceDTI= Doppler tissue imagingEACVI= EuropeanAssociation of CardiovascularImagingEDV= End-diastolic volumeEF= Ejection fractionESV= End-systolic volumeFAC= Fractional area changeGLS= Global longitudinalstrainI-I= Inner edge to inner edgeIVC= Inferior vena cavaLA= Left atrialL-L= Leading edge to leading edgeLV= Left ventricularMDCT= Multidetectorcomputed tomographyPW= Pulsed-waveRA= Right atrialRIMP= Right ventricular indexof myocardial performanceRV= Right ventricularRWT= Relative wall thicknessSTE= Speckle-trackingechocardiographyTAPSE= Tricuspid annularplane systolic excursionTAVI= Transcatheter aorticvalve implantationTAVR= Transcatheter aorticvalve replacementTEE=

In addition to providing normative data, itwould be beneficial to standardize cutoffs for severity of abnormalityfor all parameters across echocardiography laboratories, such that thetermmoderately abnormal, for example, would have the same mean-ing universally. However, different approaches may be used for deter-mining cutoff values for the different degrees of abnormality, all ofwhich have significant first approach would be to empirically define cutoffs formild, moderate, and severe abnormalities on the basis of SDs aboveor below the reference limit derived from a group of healthy advantage of this method is that these data readily exist formost echocardiographic parameters.

10 However, this approach isfundamentally flawed. First, not all echocardiographic parametersare normally distributed (or Gaussian), even in a normal , even if a particular parameter is normally distributed innormal subjects, most echocardiographic parameters, whenmeasured in the general population, have a significant asymmetricdistribution in one direction (abnormally large for size or abnormallylow for function parameters). An alternative method would be todefine abnormalities on the basis of percentile values ( , 95th,99th) of measurements derived from a population that includesboth healthy people and those with disease. Although these datawould still not be normally distributed, they would account forthe asymmetric distribution and the range of abnormality presentwithin the general population. The major limitation of this approachis that such population data sets simply do not exist for most echo-cardiographic , an approach that predicts outcomes or prognosis would bepreferred.
