Recent advances in the management of ventricular tachyarrhythmias [version 1; referees: 2 approved]
F1000Research, 2017 Ventricular arrhythmias are an important cause of cardiovascular morbidity and mortality, particularly in those with structural heart disease, inherited cardiomyopathies, and channelopathies. The goals of ventricular arrhythmia management include symptom

CaMKII-dependent regulation of cardiac Na(+) homeostasis. [PDF]
, 2014 Na(+) homeostasis is a key regulator of cardiac excitation and contraction. The cardiac voltage-gated Na(+) channel, NaV1.5, critically controls cell excitability, and altered channel gating has been implicated in both inherited and acquired arrhythmias.

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions
Advanced Science, EarlyView.This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Ventricular arrhythmias in patients with Takotsubo syndrome
Journal of Arrhythmia, 2018 Takotsubo syndrome (TTS) is a unique nonischemic cardiac disease characterized by acute myocardial dysfunction of the left and/or right ventricle. Patients are predominantly postmenopausal women and usually present with symptoms indistinguishable from ...

Advanced Science, EarlyView.This study highlights that radioimmunotherapy drives crosstalk between fibroblasts and immune cells (especially macrophages) in the cardiac microenvironment, with IL‐6 as the key mediator, and tocilizumab alleviates cardiac fibrosis by targeting this interplay.

A CLINICAL REVIEW OF VENTRICULAR ARRHYTHMIAS IN PATIENTS WITH CONGESTIVE HEART FAILURE
European Medical Journal Cardiology, 2019 Heart failure is an increasingly prevalent condition, which is associated with ventricular arrhythmias. The reduction in cardiac pumping efficiency leads to the activation of several compensatory mechanisms.

Arrhythmogenic right ventricular cardiomyopathy associated with severe left ventricular involvement in a cat. [PDF]
, 2009 An 8-year-old, 4 kg, intact female, domestic shorthaired cat was referred for tachypnea and pleural effusion. A 24-h Holter recording showed numerous polymorphic ventricular premature complexes with left and right bundle branch block morphology ...

Advanced Science, EarlyView.High electrical performance alone does not guarantee efficient bioelectronic signal transduction. Despite excellent mixed ionic‐electronic conduction, recordings from cardiomyocytes reveal that p(g2T‐TT)‐based OECTs predominantly transduce field potential FP‐like signals due to weak cell‐polymer coupling.

Smart Optogenetics for Real‐Time Automated Control of Cardiac Electrical Activity
Advanced Science, EarlyView.We are able to stop dangerous heart‐rhythm spirals before they fully form. Within about 100 ms, it pinpoints the spiral's tiny central tip (≈0.9 mm) using light‐based sensing and machine learning, then shines targeted light to shut it down. This fast, precise, closed‐loop approach detects, targets, and terminates arrhythmias in real time.
