Pediatr Transplantation 2010: 14:182–187. © 2009 John Wiley & Sons A/S. Abstract:  Intrapatient consistency relative utility of TDI as well other echocardiographic parameters are incompletely understood HTx We sought to evaluate the strength common used evaluation recipients, including TDI. reviewed 388 echocardiograms 73 catheterizations from 34 recipients without coronary disease over an 18-month period. Data included systolic diastolic parameters, with VCFc mitral annular velocities. descriptive statistics, analyzed intrapatient variability using MSR one-way anova. Echocardiographic data were compared invasively measured hemodynamic data. For most velocities, was smaller than total variability. higher normal patients. approximately 10% slower previously published studies subjects. Pediatric ranges not same healthy norms, range findings rejection is relatively broad. Serial assessment important when interpreting
