Association between CMR‐derived hepatic T1‐time, tricuspid regurgitation and survival

European Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.
We investigated the association between tricuspid regurgitation (TR) severity and hepatic T1‐time in 1029 patients undergoing cardiac MRI and echocardiography. Hepatic T1‐time increased progressively with TR severity and remained independently associated after adjusting for NT‐proBNP and right ventricular function. Both TR and hepatic T1‐time predicted

The impact of different geometric assumption of mitral annulus on the assessment of mitral regurgitation volume by Doppler method

Cardiovascular Ultrasound, 2020
Background Mitral regurgitation volume (MRvol) by quantitative pulsed Doppler (QPD) method previously recommended suffers from geometric assumption error because of circular geometric assumption of mitral annulus (MA).

Validation of “left ventricular early inflow-outflow index”: A novel echocardiographic method for quantification of mitral regurgitation in an Indian population with special focus on rheumatic etiology

Indian Heart Journal, 2018
Background: Quantification of mitral regurgitation (MR) has always required an “integrated approach” as there is no single gold-standard method. We investigated a new Doppler-derived parameter “left ventricular early inflow-outflow index (LVEIO)” for the

Morphological evaluation of a regurgitant orifice by 3-D echocardiography: applications in the quantification of valvular regurgitation

, 1999
The clinical evaluation of blood flow regurgitation through a heart valve or stenotic lesion is an unresolved problem. The proximal flowfield region has been the study focus in the last few years; however, investigators have failed to identify an ...

B-type natriuretic peptide as an index of symptoms and severity of chronic rheumatic mitral regurgitation

Heart Views, 2016
Background: The most common causes of severe mitral regurgitation (MR) in developing countries are rheumatic heart disease. The plasma level of B-type natriuretic peptide (BNP) is known to increase with left ventricular (LV) dysfunction. Aim of the Work:

Prognostic implications of sex-related disparities in severity assessment of primary mitral regurgitation following intervention

Open Heart
Background Current guidelines advocate for intervention in primary mitral regurgitation (PMR) based on detection of severe MR using standardised thresholds.

Mechanism of dynamic regurgitant orifice area variation in functional mitral regurgitation

, 1999
ObjectivesWe used the Doppler proximal flow convergence technique as a physiologic tool to explore the effects of the time courses of mitral annular area and transmitral pressure on dynamic changes in regurgitant orifice area.BackgroundIn functional ...

A novel transcatheter tricuspid annuloplasty for severe tricuspid valve regurgitation via the K-clip™ system: early experience in China

Frontiers in Cardiovascular Medicine
BackgroundPatients who suffer from severe tricuspid regurgitation (TR) do not undergo standard care therapy because of the high surgical risk. As a result, safer and less invasive techniques are being sought after internationally.

Quantification of Multiple Mitral Regurgitant Jets: An In Vitro Validation Study Comparing Two- and Three-Dimensional Proximal Isovelocity Surface Area Methods [PDF]

, 2017
BACKGROUND: The accuracy of the proximal isovelocity surface area (PISA) method for the quantification of mitral regurgitation (MR), in the case of multiple jets, is unknown.
