The European Network for Translational Research in Atrial Fibrillation (EUTRAF): objectives and initial results. [PDF]
, 2015 Atrial fibrillation (AF) is the most common sustained arrhythmia in the general population. As an age-related arrhythmia AF is becoming a huge socio-economic burden for European healthcare systems. Despite significant progress in our understanding of the

Automatic Mapping of Atrial Fiber Orientations for Patient-Specific Modeling of Cardiac Electromechanics using Image-Registration [PDF]
arXiv, 2018 Knowledge of appropriate local fiber architecture is necessary to simulate patient-specific electromechanics in the human heart. However, it is not yet possible to reliably measure in-vivo fiber directions, especially in human atria. Thus, we present a method which defines the fiber architecture in arbitrarily shaped atria using image registration and ...

Implantable Self‐Powered Systems for Electrical Stimulation Medical Devices
Advanced Science, EarlyView.In this paper, the design strategy and clinical application of ISS are discussed in depth from four aspects: the design and optimization of the energy collection module, the selection and preparation of adaptive electrode materials, the innovation of system design strategy, and the biological effect of electrical stimulation of ISS.

A neonate with ‘amphibian heart’: A rare combination of complex congenital heart diseases
IHJ Cardiovascular Case Reports, 2021 Persistent truncus arteriosus is a rare congenital malformation of the heart. It arises from the ventricular cavity through a common ventriculo-arterial junction and is usually associated with doubly committed ventricular septal defect.

Calcium in the Pathophysiology of Atrial Fibrillation and Heart Failure
Frontiers in Physiology, 2018 Atrial fibrillation (AF) is commonly associated with heart failure. A bidirectional relationship exists between the two—AF exacerbates heart failure causing a significant increase in heart failure symptoms, admissions to hospital and cardiovascular death,

Advanced Science, EarlyView.In the context of chronic hyperglycemia, a DDR is initiated, leading to the pathological activation of DNA‐PKcs in the diabetic heart. This activated DNA‐PKcs directly interacts with and phosphorylates YAP1 at Thr226, thereby increasing the nuclear expression of YAP1.

Dynamics of cardiac re-entry in micro-CT and serial histological sections based models of mammalian hearts [PDF]
arXiv, 2018 Cardiac re-entry regime of self-organised abnormal synchronisation underlie dangerous arrhythmias and fatal fibrillation. Recent advances in the theory of dissipative vortices, experimental studies, and anatomically realistic computer simulations, elucidated the role of cardiac re-entry interaction with fine anatomical features in the heart, and ...
