1020-7 Afterload Dependence of Mitral Regurgitant Volume and Regurgitant Orifice Area by Quantitative Doppler

Journal of the American College of Cardiology, 1995
Quantitation of the severity of mitral regurgitation (MR) is complicated by changes in loading conditions that occur either spontaneously or as a result of therapy. Effective regurgitant orifice area has been proposed as a more fundamental measure of the severity of MR than regurgitant volume.

IMPACT OF THE ETIOLOGY OF MITRAL REGURGITATION ON CALCULATION OF REGURGITANT VOLUME USING THE PROXIMAL FLOW CONVERGENCE METHOD

Journal of the American College of Cardiology, 2013
To evaluate the impact of mitral regurgitation (MR) etiology on the accuracy of the proximal isovelocity surface area (PISA) method, we compared PISA method with conventional volumetric method in 176 patients with degenerative MR (prolapse or flail, group A) and 126 with functional MR (group B).

Retrospective Evaluation of Transcatheter Edge‐To‐Edge Mitral Valve Repair in Dogs With Myxomatous Mitral Valve Disease

Journal of Veterinary Internal Medicine
Background Transcatheter edge‐to‐edge repair (TEER) is an emerging minimally invasive mitral valve repair treatment for dogs with myxomatous mitral valve disease (MMVD), but reports on its outcomes are limited.

Left ventricular dysfunction in hypertensive patients and inter-arm pressure difference

Journal of Indian College of Cardiology
Background: Systolic inter-arm pressure difference (SIAD) is considered as cardiovascular risk. We aimed to ascertain whether the presence of (SIAD) is associated with impaired left ventricular (LV) functions or not.

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

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
