Optimal Quantification of Functional Mitral Regurgitation: Comparison of Volumetric and Proximal Isovelocity Surface Area Methods to Predict Outcome

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Effective orifice area (EOA) ≥0.2 cm2 or regurgitant volume (Rvol) ≥30 mL predicts prognostic significance in functional mitral regurgitation (FMR).

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.

Quantification of Mitral Valve Regurgitation in Cavalier King Charles Spaniels and Chihuahuas Using Radius of Proximal Isovelocity Surface Area [PDF]

Animals
Mitral regurgitation (MR) resulting from myxomatous mitral valve disease (MMVD) is a prevalent condition in dogs, particularly smaller breeds like Cavalier King Charles Spaniels (CKCSs) and Chihuahuas (CHHs).

Novel 3-dimensional effective regurgitation orifice area quantification serves as a reliable tool to identify severe mitral valve regurgitation [PDF]

Scientific Reports
A precise quantification of mitral regurgitation (MR) severity is essential for treatment and outcome of patients with MR. 3D echocardiography facilitates estimation of MR but selection of patients with necessity of invasive treatment remains challenging.

Impact of measurement location on direct mitral regurgitation quantification using four-dimensional flow cardiovascular magnetic resonance [PDF]

Journal of Cardiovascular Magnetic Resonance
Background: Four-dimensional (4D) flow cardiovascular magnetic resonance (CMR) shows promise for quantifying mitral regurgitation (MR) by allowing for direct regurgitant volume (RVol) measurement using a plane precisely placed at the MR jet. However, the

Proximal isovelocity surface area method for assessment of mitral regurgitation severity: Principles, pitfalls, and future directions

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2021
Quantification of mitral regurgitation (MR) is important in clinical practice. As fluid approaches a finite circular orifice, concentric hemispherical shells are formed with gradually decreasing surface area and increasing velocity. Severity of MR by the

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 ...
