Figure 1

Left: An example of a patient with severe TR assessed by both echocardiography (top right) and by CMR in short axis view, showing a signal loss in an area in the right atrium due to TR. This TR jet area is shown without (left, zoomed insert) and with (bottom right) the manual tracing and measured values. Right: CMR-derived TR assessment by jet area and normalized signal intensity. With increasing severity of the TR, the area increased and the normalized signal intensity decreased (all p < 0.05).
