AORTIC ANNULUS SIZING FOR TRANSAPICAL HEART VALVE IMPLANTATION: AN AGREEMENT ANALISYS OF DIFFERENT THREE-DIMENSIONAL TRANSOESOPHAGEAL ECHOCARDIOGRAPHIC MODALITIES AND CARDIAC COMPUTED TOMOGRAPHY SCAN

Linear regression, variation coefficients (VC) intra-class correlation coefficients (ICC) and concordance correlation coefficients (CCC) were used to test agreement with MDCT measures obtained at level of virtual basal ring Results: 3DTEE derived CSA calculated either by virtual ring or computed methods was lower than that measured at CT (p=0.003 and p=0.04 respectively, Table 1) wheras negligible difference was obtained by the direct annulus planimetry method (p=0.31).
