Assessment of left atrial function by MRI myocardial feature tracking
Left atrium (LA) volumes and function are predictors of cardiovascular events. Because LA function cannot be assessed from cardiovascular magnetic resonance imaging (MRI) using the well‐establishedExpand

Cardiac MR Strain: A Noninvasive Biomarker of Fibrofatty Remodeling of the Left Atrial Myocardium.
Purpose To determine whether left atrial (LA) strain quantification with cardiac magnetic resonance (MR) imaging feature tracking is associated with the severity of LA fibrofatty myocardialExpand
Left atrial aging: a cardiac magnetic resonance feature-tracking study.
Importance of left atrial (LA) phasic function evaluation is increasingly recognized for its incremental value in terms of prognosis and risk stratification. LA phasic deformation in the pathway ofExpand
Impact of obesity and epicardial fat on early left atrial dysfunction assessed by cardiac MRI strain analysis
AbstractBackgroundDiastolic dysfunction is a major cause of morbidity in obese individuals. We aimed to assess the ability of magnetic resonance imaging (MRI) derived left atrial (LA) strain toExpand
Localized transvalvular pressure gradients in mitral bileaflet mechanical heart valves and impact on gradient overestimation by Doppler.
BACKGROUND It has been reported that localized high velocity may be recorded by continuous-wave Doppler interrogation through the smaller central orifices of bileaflet mechanical heart valves (BMHV)Expand
In vitro study of valve-in-valve performance with the CoreValve self-expandable prosthesis implanted in different positions and sizes within the Trifecta surgical heart valve

Effect of oversizing and elliptical shape of aortic annulus on transcatheter valve hemodynamics: An in vitro study.
BACKGROUND Transcatheter aortic valve implantation (TAVI) is often performed in patients with non-circular aortic annulus and in oversizing (OS) conditions. The impact of elliptical annulus shape andExpand
Mitral valve-in-valve hemodynamic performance: An in vitro study.
OBJECTIVES The valve-in-valve (VinV) procedure may be used in high-risk patients with failed mitral surgical bioprostheses. The objective of this in vitro study was to assess the hemodynamic functionExpand
Effect of size and position of self-expanding transcatheter valve on haemodynamics following valve-in-valve procedure in small surgical bioprostheses: an in vitro study.
AIMS The valve-in-valve (ViV) procedure has become a valuable alternative for the treatment of failed surgical bioprostheses (BP) in high-risk patients. However, in small BP, the clinical outcomesExpand
