Disproportionate Mitral Regurgitation Determines Survival in Acute Heart Failure

Frontiers in Cardiovascular Medicine, 2021
Objectives: To assess the prevalence and impact of mitral regurgitation (MR) on survival in patients presenting to hospital in acute heart failure (AHF) using traditional echocardiographic assessment alongside more novel indices of proportionality ...

Is there a role for cardiovascular magnetic resonance imaging in the assessment of biological aortic valves?

Frontiers in Cardiovascular Medicine, 2023
Patients with biological aortic valves (following either surgical aortic valve replacement [SAVR] or trans catheter aortic valve implantation [TAVI]) require lifelong follow-up with an imaging modality to assess prosthetic valve function and dysfunction.

Echocardiographic evaluation of the functional mitral regurgitation after cardiac resynchronization therapy: which is the best approach? [PDF]

Archives of the Balkan Medical Union, 2020
A strong association between functional mitral regurgitation severity and all-cause mortality and hospitalization was found in patients with dilated cardiomyopathy and left ventricular systolic dysfunction, with or without an implanted device.

Usefulness of Vena Contracta for Identifying Severe Secondary Mitral Regurgitation: A Three-Dimensional Transesophageal Echocardiography Study

Reviews in Cardiovascular Medicine, 2023
Background: In secondary mitral regurgitation (SMR), effective regurgitant orifice area by the proximal isovelocity surface area method (EROAPISA) evaluation might cause an underestimation of regurgitant orifice area because of its ellipticity compared ...

Beyond effective regurgitant orifice in quantitative assessment of tricuspid regurgitation: impact on clinical outcomes [PDF]

European Heart Journal, 2020
Abstract Background Quantification in tricuspid regurgitation has been poorly investigated. Recommended methods and thresholds are directly translated from mitral regurgitation; however, the anatomy, hemodynamics, and regurgitant orifice geometry are different in TR. Effective regurgitant orifice (ERO)

In vitro Assessment of the Impacts of Leaflet Design on the Hemodynamic Characteristics of ePTFE Pulmonary Prosthetic Valves

Frontiers in Bioengineering and Biotechnology, 2020
Prosthetic pulmonary valves are widely used in the management procedures of various congenital heart diseases, including the surgical pulmonary valve replacement (PVR) and right ventricular outflow tract reconstruction (RVOT).

Intraoperative comparison of 2D versus 3D transesophageal echocardiography for quantitative assessment of mitral regurgitation

Annals of Cardiac Anaesthesia, 2021
Background: Effective regurgitant orifice area (EROA) can be represented by 3D echocardiographic vena contracta cross-sectional area (3D-VCA) as a reference method for the quantification of mitral regurgitation (MR) without making any geometrical ...

ASSESSMENT OF MITRAL REGURGITATION SEVERITY BY DIFFERENT ECHOCARDIOGRAPHIC METHODS IN COMPARISON WITH LEFT VENTRICLE ANGIOGRAPHY

The Iraqi Journal of Medical Sciences, 2016
Background:Proximal isovelocity surface area method and mitral regurgitatant jet estimation (with its ratio to left atrium) are reliable methods for estimation of mitral regurgitation severity aiding in management strategy, precluding the use of other ...

Comprehensive assessment of the aortic valve in critically ill patients for the non-cardiologist. Part II: Chronic aortic regurgitation of the native valve

Anaesthesiology Intensive Therapy, 2021
Inadequate diastolic closure of the aortic valve causes aortic regurgitation (AR). Diastolic regurgitation towards the left ventricle (LV) causes LV volume overload, resulting in eccentric LV remodelling.

NT-proBNP increase during stress echocardiography predicts significant changes in ischemic mitral regurgitation severity in patients qualified for surgical revascularization

Cardiology Journal, 2022
BACKGROUND: In many patients, significant changes in ischemic mitral regurgitation (IMR) severity during exercise can be observed independent of the degree of IMR at rest.
