Usefulness of Vena Contracta for Identifying Severe Secondary Mitral Regurgitation: A Three-Dimensional Transesophageal Echocardiography Study [PDF]
Reviews 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 ...

Benefit of 3D Vena Contracta Area over 2D-Based Echocardiographic Methods in Quantification of Functional Mitral Valve Regurgitation [PDF]
Diagnostics, 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 ...

Vena contracta area measurement by three-dimensional echocardiography for assessing mitral regurgitation severity using a novel, fast, and reliable method [PDF]
BMC Cardiovascular DisordersBackground Echocardiography is the standard tool for the evaluation of mitral regurgitation (MR). Although Two-dimensional echocardiography is the most recommended tool, it has some limitations.

3D vena contracta area after MitraClip© procedure: precise quantification of residual mitral regurgitation and identification of prognostic information [PDF]
Cardiovascular Ultrasound, 2018 Background Percutaneous mitral valve repair (PMVR) is increasingly performed in patients with severe mitral regurgitation (MR). Post-procedural MR grading is challenging and an unsettled issue. We hypothesised that the direct planimetry of vena contracta

Percutaneous Removal of a Tricuspid Valve Vegetation Using the AngioVac System in a Young Woman Who Injects Drugs [PDF]
DiagnosticsRight-sided infective endocarditis (RSIE) is a difficult clinical problem, particularly among people who inject drugs (PWID), in whom large tricuspid vegetations may be complicated by severe regurgitation and septic pulmonary embolization.

REC: Interventional Cardiology (English Ed.), 2022 Initially, percutaneous mitral clip emerges as an alternative to surgery in patients with severe mitral regurgitation (MR) and high surgical risk. Nonetheless, it is now also considered a first-line treatment in patients with left ventricular ejection ...

Pre-procedural predictors for multiple clips in percutaneous edge-to-edge mitral valve repair
The Egyptian Heart Journal, 2021 Background Percutaneous mitral valve (MV) clipping for mitral regurgitation (MR) revolutionized MV repair; however, valve anatomies and pathologies vary. Often multiple clips are required, and predicting this pre-procedurally would be useful.

Assessment of Mitral Regurgitation Severity by measuring of Vena Contracta Area Using Transesophageal and Transthoracic Three-Dimensional Echocardiography [PDF]
Al-Azhar International Medical Journal, 2020 Background: Mitral regurgitation (MR) is one of the most common derangement of native valves and increases in prevalence with age. We aimed to compare the accuracy of the vena contracta area measurement (VCA) by 3-dimensional transesophageal (3D-TEE ...
