Résumé
Tricuspid annular (TA) dilation is a key process in functional tricuspid regurgitation, but normal TA dimensions using cardiovascular magnetic resonance have not been established. We measured TA diameters in 66 healthy volunteers, aged 38 ± 11 years, during 3 different phases of the cardiac cycle (end-systole, early diastole, and end-diastole) and in 2 routinely acquired cardiovascular magnetic resonance imaging planes (4-chamber [4C] and right ventricular inflow-outflow [RVIO]). Three readers independently measured each value and 1 reader repeated measurements 1 month apart. The upper limit of normal (ULN) was calculated as 1.96 standard deviations above the mean. We assessed inter- and intraobserver reliability using the intraclass correlation coefficient (ICC) and Bland-Altman analysis. We found the TA diameter largest during early diastole in the 4C view with an ULN of 43 mm (22 mm/m
