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 Disorders
Background 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]

Diagnostics
Right-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.

Intraoperative Quantification of Severe Mitral Regurgitation: A Comparative Assessment of Two-Dimensional Flow Convergence, Three-Dimensional Volumetric, and Doppler-Based Methods [PDF]

Journal of Cardiovascular Development and Disease
Accurate quantification of mitral regurgitation (MR) is central to perioperative decision-making, yet the agreement and interchangeability of commonly used echocardiographic methods remain uncertain.

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

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

Assessment of chronic aortic regurgitation using end-diastolic flow reversal in the upper descending aorta: diagnostic accuracy and prediction of aortic valve surgery in a prospective echocardiography and cardiac magnetic resonance imaging study [PDF]

Echo Research and Practice
Background This study aimed to assess the utility of end-diastolic flow reversal in the upper descending aorta (EFR) for echocardiographic grading of aortic regurgitation (AR) severity, using cardiac magnetic resonance imaging (CMRI) as the reference ...

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

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 ...

Intraoperative echocardiographic assessment of mitral regurgitation after mitral clip implantation: literature review

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 ...

Clinical impact of aortic valve replacement in patients with moderate mixed aortic valve disease

Frontiers in Cardiovascular Medicine, 2023
BackgroundInformation is scarce regarding the clinical implications of aortic valve replacement (AVR) for patients suffering from moderate mixed aortic valve disease (MAVD), characterized by a combination of moderate aortic stenosis (AS) and ...
