Simulation of left ventricle fluid dynamics with mitral regurgitation from magnetic resonance images with fictitious elastic structure regularization [PDF]

arXiv, 2017
Computer modeling can provide quantitative insight into cardiac fluid dynamics phenomena that are not evident from standard imaging tools. We propose a new approach to modeling left ventricle fluid dynamics based on an image-driven model-based description of ventricular motion. In this approach, the end-diastolic geometry and time-dependent deformation

Circulating endothelial cells and vascular cell adhesion molecule-1 correlates with severity of regurgitation lesion and heart failure in rheumatic heart disease

Journal of Experimental and Integrative Medicine, 2015
Objective: This study aims to determine the correlation of vascular cell adhesion molecule-1 (VCAM-1) and circulating endothelial cells (CEC) with cardiac valves lesion severity and heart failure (HF) in rheumatic heart disease (RHD). Methods: A cross-sectional observational study using human peripheral blood samples of 36 children aged 6 to14 years ...

Coronary Artery Bypass Surgery With or Without Mitral Valve Annuloplasty in Moderate Functional Ischemic Mitral Regurgitation: Final Results of the Randomized Ischemic Mitral Evaluation (RIME) Trial

Circulation, 2012
Background—The role of mitral valve repair (MVR) during coronary artery bypass grafting (CABG) in patients with moderate ischemic mitral regurgitation (MR) is uncertain.

The risk of death according to left ventricular ejection fraction and right ventricular dilatation in 17 321 adults with heart failure from 40 high‐, middle‐ and low‐income countries – A Global Congestive Heart Failure (G‐CHF) study

European Journal of Heart Failure, EarlyView.
Abstract Aims The aim of this study was to describe the prognostic importance of left ventricular ejection fraction (LVEF) versus right ventricular (RV) dilatation and dysfunction in patients with heart failure (HF) from countries of different income levels. Methods and results We enrolled 17 321 participants with HF from 40 countries.

Prospective Comparison of Valve Regurgitation Quantitation by Cardiac Magnetic Resonance Imaging and Transthoracic Echocardiography

Circulation Cardiovascular Imaging, 2013
Background—Both transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) imaging allow quantification of chronic aortic regurgitation (AR) and mitral regurgitation (MR).

Circulating growth differentiation factor‐15 levels are associated with early echocardiographic signs of diastolic function impairment in the STANISLAS cohort: A 20‐year follow‐up study

European Journal of Heart Failure, EarlyView.
Summary of the study design and key findings. The (+) and (−) signs mean that the variable has a positive or a negative association with growth differentiation factor‐15 (GDF‐15) levels in the fully adjusted model (age, gender, current smoker, body mass index, total cholesterol, systolic blood pressure and N‐terminal pro‐B‐type natriuretic peptide ...

Predictors of Long-Term Outcomes in Patients With Significant Myxomatous Mitral Regurgitation Undergoing Exercise Echocardiography

Circulation, 2014
Background— Significant myxomatous mitral regurgitation leads to progressive left ventricular (LV) decline, resulting in congestive heart failure and death. Such patients benefit from mitral valve surgery.

Clinical and plasma proteomic characterization of heart failure with supranormal left ventricular ejection fraction: An emerging entity of heart failure

European Journal of Heart Failure, EarlyView.
Heart failure (HF) with supranormal ejection fraction (HFsnEF) is an unnoticed but emerging entity in HF. This study showed that HFsnEF carries a similarly increased cardiovascular risk as HF with reduced ejection fraction (HFrEF) and distinct structural and proteomic characteristics from HFrEF, warranting a further comprehensive understanding and ...

Transcatheter Therapy of Mitral Regurgitation

Circulation, 2014
The mitral valve apparatus is a complex structure that incorporates the leaflets, chordae tendinae, papillary muscles, annulus, and left ventricle (LV) in its function. As a result, diseases that affect any of these structures can result in severe mitral

Acute kidney injury after lung transplantation, incidence, risk factors, and effects: A Swedish nationwide study. [PDF]

Acta Anaesthesiol Scand
Abstract Background Acute kidney injury (AKI) is a serious complication after lung transplantation, but the reported incidence varies in the literature. No data on AKI have been published from the Swedish lung transplantation program. Methods The aim of our study was to investigate the incidence, perioperative risk factors, and effects of early ...
