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

open access: yesEchocardiography
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 ...

Classic Murmur, Unexpected Diagnosis: A Case Report and Pathophysiological Review. [PDF]

open access: yesCase Rep Cardiol
A systolic murmur best heard at the aortic area with radiation to the neck is considered a hallmark of aortic stenosis. We report a patient with this auscultatory pattern in whom investigation revealed an unexpected diagnosis. Accompanying symptoms reinforced the initial suspicion, adding another layer of complexity to the diagnostic process. This case

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

open access: yesCardiovascular 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.

Quantification of Flow Rates and Flow Volumes in Valve Regurgitation Using 3-D High Frame-Rate Ultrasound

open access: yesIEEE Open Journal of Ultrasonics, Ferroelectrics, and Frequency Control, 2023
Valve regurgitation is a cardiac condition caused by the incomplete closure of a cardiac valve. Untreated, this condition may result in cardiac failure.

Benefit of 3D Vena Contracta Area over 2D-Based Echocardiographic Methods in Quantification of Functional Mitral Valve Regurgitation

open access: yesDiagnostics, 2023
Background: The two-dimensional proximal isovelocity surface area (2D PISA) method in the quantification of an effective regurgitation orifice area (EROA) has limitations in functional mitral valve regurgitation (FMR), particularly in non-circular ...

Prevalence and Prognostic Importance of Massive Tricuspid Regurgitation in Patients Undergoing Tricuspid Annuloplasty With Concomitant Left-Sided Valve Surgery: A Study on Rheumatic Valvular Heart Disease

open access: yesFrontiers in Cardiovascular Medicine, 2022
BackgroundThe presence of tricuspid regurgitation (TR) is very common in patients with concomitant left-sided valve disease. Recent studies have advocated an additional grading of massive TR that is beyond severe. The present study sought to characterize

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

open access: yesThe 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 ...

Usefulness of Vena Contracta for Identifying Severe Secondary Mitral Regurgitation: A Three-Dimensional Transesophageal Echocardiography Study

open access: yesReviews in Cardiovascular Medicine, 2023
Background: In secondary mitral regurgitation (SMR), effective regurgitant orifice area by the proximal isovelocity surface area method (EROAPISA) evaluation might cause an underestimation of regurgitant orifice area because of its ellipticity compared ...
