Background Today, there is no accepted approach to evaluate tricuspid regurgitation (TR) using cardiovascular magnetic resonance (CMR). Contrary to 4-chamber imaging planes, which often do not show the entire regurgitant jet, these jets are readily visualized in short-axis views in the right atrium (RA). We hypothesized that the size and signal intensity (SI) of the cross-sectional jet area in the short-axis views would reflect TR severity. Methods We studied 61 patients with ≥mild TR on echocardiography, who underwent CMR within 24 hours. The severity of TR was determined by color Doppler vena contracta (VC): severe (VC≥7 mm; N = 20), moderate (3<VC<7 mm; N = 21) and mild (VC≤3 mm; N = 20). CMR TR jet area and mean SI (normalized by that in the RA cavity away from the jet) were measured in a single short-axis frame that depicted maximum area.
