Three-Dimensional Transesophageal Echocardiographic Vena Contracta Area for Grading Mitral Regurgitation: Severity Cut-offs From a Prospective Tunisian Cohort. [PDF]

Echocardiography
Three‐dimensional vena contracta area (VCA) measured by transoesophageal echocardiography enables precise accurate quantification of mitral regurgitation severity. In a Tunisian cohort, 3D VCA showed strong correlations with conventional 2D indices and excellent diagnostic performance for severe MR, supporting its use particularly in rheumatic mitral ...

Three-dimensional transthoracic echocardiographic evaluation of tricuspid regurgitation severity using proximal isovelocity surface area: comparison with volumetric method

Cardiovascular Ultrasound, 2020
Background The quantification of tricuspid regurgitation(TR) using three-dimensional(3D) proximal isovelocity surface area (PISA) derived effective regurgitant orifice area (EROA) is feasible in functional TR.

Echocardiography vs. CMR in the Quantification of Chronic Mitral Regurgitation: A Happy Marriage or Stormy Divorce?

Journal of Cardiovascular Development and Disease, 2023
Quantification of chronic mitral regurgitation (MR) is essential to guide patients’ clinical management and define the need and appropriate timing for mitral valve surgery.

Echocardiographic evaluation of the functional mitral regurgitation after cardiac resynchronization therapy: which is the best approach? [PDF]

Archives of the Balkan Medical Union, 2020
A strong association between functional mitral regurgitation severity and all-cause mortality and hospitalization was found in patients with dilated cardiomyopathy and left ventricular systolic dysfunction, with or without an implanted device.

A novel fully automated method for mitral regurgitant orifice area quantification [PDF]

, 2013
BackgroundEffective regurgitant orifice area (EROA) in mitral regurgitation (MR) is difficult to quantify. Clinically it is measured using the proximal isovelocity surface area (PISA) method, which is intrinsically not automatable, because it requires ...

Predictors of Mortality in Patients With Severe Ischemic Cardiomyopathy Undergoing Surgical Mitral Valve Intervention

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundIschemic mitral regurgitation is associated with substantial risk of death. Although surgical mitral valve intervention (MVi) may improve symptoms, it has not been shown to improve survival.

Is there a role for cardiovascular magnetic resonance imaging in the assessment of biological aortic valves?

Frontiers in Cardiovascular Medicine, 2023
Patients with biological aortic valves (following either surgical aortic valve replacement [SAVR] or trans catheter aortic valve implantation [TAVI]) require lifelong follow-up with an imaging modality to assess prosthetic valve function and dysfunction.

ASSESSMENT OF MITRAL REGURGITATION SEVERITY BY DIFFERENT ECHOCARDIOGRAPHIC METHODS IN COMPARISON WITH LEFT VENTRICLE ANGIOGRAPHY

The Iraqi Journal of Medical Sciences, 2016
Background:Proximal isovelocity surface area method and mitral regurgitatant jet estimation (with its ratio to left atrium) are reliable methods for estimation of mitral regurgitation severity aiding in management strategy, precluding the use of other ...
