Mitral Regurgitation Severity Analysis Based on Features and Optimal HE (OHE) with Quantification using PISA Method

Journal of Intelligent Systems, 2017
Heart disease is the foremost reason for death and also the main source of incapability in the developed nations. Mitral regurgitation (MR) is a typical heart disease that does not bring about manifestations until its end position.

Segmentation of jet area to quantity the severity of mitral regurgitation by color Doppler echocardiography

International Journal of Noncommunicable Diseases, 2018
Mitral regurgitation (MR) is a disorder of mitral valve and it is one of the most common causes of cardiovascular morbidity and mortality. Mitral valve allows blood to flow from left atrium, to the left ventricle and Mitral Valve regurgitation results in

When Myocardial Injury in Lupus Is Not Lupus: Probable Antimalarial‐Associated Cardiomyopathy Mimicking Lupus Myocarditis

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Antimalarial cardiotoxicity may mimic lupus myocarditis in systemic lupus erythematosus. We report a 53‐year‐old woman with chronic antimalarial exposure, myocardial injury, biventricular dysfunction, electrical abnormalities, low lupus activity, and no myocardial edema.

Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

Quantification of regurgitation in mitral valve prolapse with four-dimensional flow cardiovascular magnetic resonance

Journal of Cardiovascular Magnetic Resonance, 2021
Background Four-dimensional cardiovascular magnetic resonance (CMR) flow assessment (4D flow) allows to derive volumetric quantitative parameters in mitral regurgitation (MR) using retrospective valve tracking.

Study of Tricuspid Valve Regurgitation by 2D and 3D Echocardiography: Comparison Between Transthoracic and Transesophageal Examination for Screening Interventions

Echocardiography, Volume 43, Issue 4, April 2026.
Forty‐two patients with significant tricuspid regurgitation (TR) underwent transthoracic (TTE) and transesophageal (TEE) echocardiography. The same day wo‐dimensional (2D) and three‐dimensional (3D) parameters obtained with both modalities were compared.

Predictors of Mortality in Patients With Severe Ischemic Cardiomyopathy Undergoing Surgical Mitral Valve Intervention

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundIschemic mitral regurgitation is associated with substantial risk of death. Although surgical mitral valve intervention (MVi) may improve symptoms, it has not been shown to improve survival.
