Figure 1

Calculation of RV parameters. Delineation of right ventricular endocardial and epicardial borders using semi-automated software, and summing up over all contiguous slices covering the right ventricle allows the calculation of all volume, mass and functional parameters. Representative images are shown for end-diastole and end-systole together with tricuspid valve plane tracking (indicated by the yellow line on the four-chamber view). The RV blood pool is shown in blue, the LV blood pool in orange and the myocardium in beige.
