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

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 ...

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 ...
