A novel fully automated method for mitral regurgitant orifice area quantification [PDF]

, 2013
BackgroundEffective regurgitant orifice area (EROA) in mitral regurgitation (MR) is difficult to quantify. Clinically it is measured using the proximal isovelocity surface area (PISA) method, which is intrinsically not automatable, because it requires ...

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).

Tricuspid Regurgitation in Acute Heart Failure: Predicting Outcome Using Novel Quantitative Echocardiography Techniques

Diagnostics, 2022
Background: The prognostic impact of tricuspid regurgitation (TR) in acute heart failure (AHF) remains uncertain. Methods: We retrospectively assessed 418 consecutive AHF patients who underwent comprehensive echocardiographic assessment within 24 h of ...

Acute and Chronic Changes in Myocardial Work Parameters in Patients with Severe Primary Mitral Regurgitation Undergoing Transcatheter Edge-to-Edge Repair

Journal of Cardiovascular Development and Disease, 2023
Background: The noninvasive assessment of myocardial work (MW) allows for the evaluation of left ventricular (LV) performance by considering the effect of LV afterload.

Treatment of Tricuspid Regurgitation With the FORMA Repair System

Frontiers in Cardiovascular Medicine, 2018
Background: Tricuspid regurgitation (TR) is common and undertreated as the risk of surgery is high in this patient population. Transcatheter devices offer treatment with a lower procedural risk.

Change in Lung Fluid Volume during Exercise in Patients with Exercise-Induced Mitral Regurgitation

Medicina, 2022
Exercise-induced mitral regurgitation (MR) can be diagnosed during stress echocardiography testing. Remote dielectric sensing (ReDSTM) is a noninvasive electromagnetic-based modality to measure lung fluid levels.

Dynamic aspects of acute mitral regurgitation: effects of ventricular volume, pressure and contractility on the effective regurgitant orifice area. [PDF]

Circulation, 1979
The dynamics of acute mitral regurgitation were studied in six open-chest dogs in whom a portion of the anterior leaflet was excised. Phasic mitral and aortic flows were measured electromagnetically and left ventricular filling volume, regurgitant volume (RV) and forward stroke volume (SV) were calculated.

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

, 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
