Comparison of 2D vena contracta area with 3D planimetric mitral valve area in rheumatoid mitral valve disease

open access: yes, 2020
Rheumatoid valve disease is a general health problem of developing countries, and it mainly affects after the age of 40. Assessment of the correct mitral valve area (MVA) is important for the treatment of rheumatoid valve disease.

3D localization of vena contracta using Doppler ICE imaging in tricuspid valve interventions

open access: yes, 2022
PURPOSE: Tricuspid valve (TV) interventions face the challenge of imaging the anatomy and tools because of the ‘TEE-unfriendly’ nature of the TV. In edge-to-edge TV repair, a core step is to position the clip perpendicular to the coaptation gap.

Intraoperative comparison of 2D versus 3D transesophageal echocardiography for quantitative assessment of mitral regurgitation

open access: yesAnnals of Cardiac Anaesthesia, 2021
Background: Effective regurgitant orifice area (EROA) can be represented by 3D echocardiographic vena contracta cross-sectional area (3D-VCA) as a reference method for the quantification of mitral regurgitation (MR) without making any geometrical ...

On Nonuniform Flow Characteristics at the Vena Contracta

open access: yes, 1970
The kinetic energy correction factor for the flow at the vena contracta is calculated using experimental data and a modified Bernoulli equation. Based on an assumption of similarity of the profiles upstream and downstream of an orifice, two other ...

The Conundrum of Tricuspid Regurgitation Grading

open access: yesFrontiers in Cardiovascular Medicine, 2018
Findings from early percutaneous tricuspid intervention trials have shown that the severity of tricuspid regurgitation (TR) far exceeded the current definition of severe TR.

Procedural success of transcatheter annuloplasty in ventricular and atrial functional tricuspid regurgitation

open access: yesFrontiers in Cardiovascular Medicine, 2023
BackgroundTranscatheter annuloplasty is meant to target annular dilatation and is therefore mainly applied in functional tricuspid regurgitation (TR).

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

open access: yesHeart 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:
