  1. Results of volumetric and 4D flow CMR
  2. To test for differences between the different groups (last column) ANOVA with posthoc Dunnets (controls as reference) was used for normally distributed data and Kruskal Wallis analysis of variance with Mann Whitney U tests (controls as reference) for non-normally distributed data. #p < 0.05, *p < 0.01 and **p < 0.001. Abbreviations: 4D-TV FW 4D tricuspid valve forward flow, 4D-TV BW 4D tricuspid valve backward flow, 4D-SV TV 4D tricuspid valve effective flow, 4D-TV reg 4D flow tricuspid valve regurgitation, 2D-SV PA 2D pulmonary valve effective flow, TVann 4CH tricuspid annulus diameter in 4-chamber view, TVann 2CH tricuspid valve annulus diameter in 2-chamber view
