Parameter variations in personalized electrophysiological models of human heart ventricles. [PDF]
PLoS ONE, 2021 The objectives of this study were to evaluate the accuracy of personalized numerical simulations of the electrical activity in human ventricles by comparing simulated electrocardiograms (ECGs) with real patients' ECGs and analyzing the sensitivity of the

Association of Abnormal Serum L-Carnitine Levels with Idiopathic Changes in Left Ventricular Geometry in Pediatric and Adolescent Patients [PDF]
Iranian Journal of Medical Sciences, 2022 Background: There is no compelling evidence to prove an association between serum free L-carnitine levels and changes in left ventricular (LV) geometry. The present study aimed to evaluate a possible association between these parameters.

Investigation of human coronary arteries and heart ventricles mode of deformation and haemodynamics
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011 Mechanical properties of coronary arteries and heart tissues, computer 3D models of CA and heart ventricles were investigated. Numerical analysis of coronary arteries and heart ventricles mode of deformation and haemodynamics was made.

Persistent ventricle partitioning in the adult zebrafish heart [PDF]
Journal of Cardiovascular Development and Disease, 2021 AbstractThe vertebrate heart integrates cells from the early-differentiating first heart field (FHF) and the later-differentiating second heart field (SHF) emerging from the lateral plate mesoderm. In mammals, this process forms the basis for the development of the left and right ventricle chambers and subsequent chamber septation. The single ventricle-

A heart within the heart: double-chambered left ventricle [PDF]
European Heart Journal - Cardiovascular Imaging, 2008 We describe a rare congenital anomaly in a 49-year-old woman who presented with palpitations and slightly reduced exercise capacity. A double-chambered left ventricle was suspected on echocardiography and confirmed by cardiac computed tomography scanning, cardiac magnet resonance imaging, and invasive angiography.

Early surgical intervention for unusually located cardiac fibroelastomas [PDF]
Yeungnam University Journal of Medicine, 2020 Papillary fibroelastomas are the second most common primary cardiac tumor in adults. Over 80% of fibroelastomas occur on the cardiac valves, usually on the left side of the heart, while the remaining lesions are typically scattered throughout the atria ...

Numerical simulation of electrocardiograms for full cardiac cycles in healthy and pathological conditions [PDF]
, 2015 This work is dedicated to the simulation of full cycles of the electrical activity of the heart and the corresponding body surface potential. The model is based on a realistic torso and heart anatomy, including ventricles and atria.
