Imaging Needs in Novel Transcatheter Tricuspid Valve Interventions
2018, JACC: Cardiovascular ImagingCitation Excerpt :After shifting the baseline in the direction of the jet with an aliasing velocity of approximately 28 cm/s, a proximal isovelocity shell radius of >0.9 cm is consistent with severe TR. Finally, the hepatic vein flow pattern, as assessed with a pulsed-wave Doppler, may show a systolic flow reversal in the hepatic veins in significant TR (32). Such systolic reversals are considered specific (>85% probability of severe regurgitation when present) but insensitive.
Recommendations for Noninvasive Evaluation of Native Valvular Regurgitation: A Report from the American Society of Echocardiography Developed in Collaboration with the Society for Cardiovascular Magnetic Resonance
2017, Journal of the American Society of EchocardiographyCitation Excerpt :The RVol, when significant, may cause flow reversal in the receiving or proximal chamber, depending on the valve. In atrioventricular valves, valve regurgitation may result in pulmonary systolic venous flow reversal with MR or hepatic venous systolic flow reversal in cases of TR.36-39 Such systolic reversals are considered specific (>85% probability of severe regurgitation when present) but insensitive.

2016, Practice of Clinical EchocardiographyIncrease of Modified Retrograde to Antegrade Flow Ratio on Doppler Ultrasounds of the Hepatic Vein Indicating Tricuspid Regurgitation During Follow-up of Liver Transplantation: Correlation With Echocardiographic Results
2009, Transplantation ProceedingsCitation Excerpt :TR may be a sign of congestive heart failure regardless of a valvular abnormality, causing passive hepatic congestion. Several investigators have reported that DUS parameters such as a dampened or reversed flow during systole, a Doppler shift difference between systolic and diastolic flow (S-D), and systolic/diastolic flow velocity ratio (S/D ratio) correlate with right atrial and right ventricular end-diastolic pressure or angiographic evidence of TR, (r = 0.64–0.74).10–12 However, it is sometimes difficult to divide HV waves into systolic and diastolic parts, because TR is usually combined with atrial fibrillation.

2002, Journal of Thoracic and Cardiovascular SurgeryCitation Excerpt :Eighty patients (31 with type 1 disease, 30 with type 2 disease, 16 with type 3 disease, and 3 with type 4 disease) underwent simultaneous closure of a secondary foramen ovale opened by means of increased right atrial pressures. Severity of TR was graded by transthoracic echocardiography as mild to severe (1+-4+) on the basis of a composite analysis of measurements of jet area, ratio of TR jet area to right atrial area, and pulsed-wave Doppler interrogation of the hepatic veins.11 A TR jet area that was limited to the immediate atrial aspect of the tricuspid valve and filled less than 33% of the right atrium (RA) was defined as 1+.
