A coupled mitral valve -- left ventricle model with fluid-structure interaction

, 2017
Understanding the interaction between the valves and walls of the heart is important in assessing and subsequently treating heart dysfunction. With advancements in cardiac imaging, nonlinear mechanics and computational techniques, it is now possible to ...

Small vesicles, big potential: A review of innovative exosome delivery and molecular mechanisms in preclinical myocardial infarction models

Animal Models and Experimental Medicine, EarlyView.
This narrative review discusses animal models of exosome‐based myocardial infarction treatments. Emerging techniques aim to improve exosome stability, targeting, and bioavailability for MI treatment as drug delivery vehicles and regenerative mediators that promote myocardial regeneration. Abstract Exosomes have emerged as promising therapeutic carriers,

Association between the proportionality of functional mitral regurgitation and survival after mitral valve operationCentral MessagePerspective

JTCVS Open
Objective: The concept of proportionate and disproportionate functional mitral regurgitation suggests that transcatheter edge-to-edge mitral repair may benefit patients with a smaller left ventricle relative to a higher regurgitant burden.

Patient–valve mismatch: A comparison of mechanical versus biological prostheses in ischemic mitral patients undergoing chordal-sparing mitral valve replacement

Journal of Medicine in Scientific Research, 2021
Background Chordal-sparing mitral valve replacement (MVR) is now preferred over downsized annuloplasty repair in treating chronic severe ischemic mitral regurgitation.

Material transport in the left ventricle with aortic valve regurgitation

, 2018
This experimental in vitro work investigates material transport properties in a model left ventricle in the case of aortic regurgitation, a valvular disease characterized by a leaking aortic valve and consequently double-jet filling within the elastic ...

Role of echocardiography in diagnosis and risk stratification in heart failure with left ventricular systolic dysfunction [PDF]

, 2007
Heart failure (HF) is a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood.

Long‐Term Impact of Prosthesis‐Patient Mismatch After Transcatheter Aortic Valve Replacement in Patients With Small Aortic Annuli

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Prosthesis‐patient mismatch (PPM) remains common following transcatheter aortic valve replacement (TAVR) and is associated with worse clinical outcomes. PPM is of particular concern in small aortic annuli (SAA). Aims To compare the incidence, predictors, and long‐term impact of PPM in SAA TAVR.
