Quantification of Tricuspid Valve Regurgitation With 2D and 4D‐Flow MRI: Comparison of Different Methods in Adult Patients With Ebstein's Anomaly

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Ebstein's anomaly (EA) is a congenital heart disorder involving tricuspid valve dysplasia and right heart abnormalities resulting in severe tricuspid regurgitation (TR). Multiple techniques assess regurgitation severity, but their correlation with EA severity markers remains unclear. Purpose To compare MRI techniques for quantifying

Two Faces of Mitral Stenosis: Uncovering Structural and Hemodynamic Signatures of Rheumatic and Mitral Annular Calcification–Induced Disease

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Mitral annular calcification (MAC) is common and associated with increased cardiovascular risk and, when severe, mitral stenosis (MS). MAC‐related MS differs anatomically and hemodynamically from rheumatic MS (RMS), challenging standard ...

Characterization of Effective Orifice Areas of Mitral Prosthetic Heart Valves: An In-Vitro Study.

, 1970
International audienceReference values of hemodynamic parameters for the assessment of prosthetic heart valves are necessary, and ideally need to be provided by entities independent of the valve manufacturers. Thus, the study aim was to provide, in vitro,

Mitral valve stiffening in end-stage heart failure: Evidence of an organic contribution to functional mitral regurgitation

, 2005
ObjectiveMitral regurgitation is a complication for many patients with congestive heart failure. Although this regurgitation is considered purely functional, we hypothesize that the alterations in cardiac geometry and function induce dysfunctional ...

Association Between HIV Infection Duration and Left Ventricular Concentric Remodeling and Myocardial Fibrosis: A Cross‐Sectional Study Using Cardiac MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Antiretroviral therapy has transformed HIV into a chronic condition, yet cardiac injury remains a major issue. Purpose To assess the ability of cardiac MR imaging markers to predict cardiac injury and disease progression in HIV‐infected individuals. Study Type Prospective.

Design of a Miniature Tissue Culture System to Culture Mouse Heart Valves

, 2010
Valvular heart disease is a leading cause of morbidity and mortality in adults but little is known about the underlying etiology. A better understanding of the genetic and hemodynamic mechanisms involved in growth and remodeling of heart valves during ...

Point‐of‐Care Ultrasound M‐Mode Analysis Using M.mode.ify

Journal of Ultrasound in Medicine, EarlyView.
Objectives M‐mode ultrasound provides high temporal resolution imaging by rendering a single scan line over time, enabling precise measurement of rapidly moving structures. Traditional M‐mode is limited to real‐time acquisition and cannot be applied retrospectively. M.mode.ify is a novel software tool that generates M‐mode‐like tracings from video data,
