Patient selection: tricuspid regurgitation (TR)
Tricuspid regurgitation was considered severe if one or more of the criteria are present. If none were present then the TR was nonsevere.
Criteria 1 - both of the following:
(1)
inferior vena cava diameter > 2.5 cm
(2) right atrium > 18 square cm AND no atrial septal defect AND no pulmonic valve disease
Criteria 2 - both of the following:
(1) jet area > 10 square cm
(2) vena contracta width > 0.7 cm
Criteria 3 - both of the following:
(1) systolic flow reversal in the hepatic vein (holosystolic reversal of hepatic vein flow)
(2) absence of AV dissociation, ventricular pacing and/or atrial arrhythmias
Criteria 4 - both of the following:
(1) triangular continuous TR Doppler signal
(2) density of continuous signal >= density of tricuspid inflow
Performance:
• The multirater kappa coefficient improved to 0.80.
• The level of agreement improved to 90%.
• The mean reader accuracy was 92%
