Post–Myocardial Infarction Scar With Fat Deposition Shows Specific Electrophysiological Properties and Worse Outcome After Ventricular Tachycardia Ablation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Fat deposition (FD) is part of the healing process after myocardial infarction. The characteristics of FD and its impact on the outcome in patients undergoing ventricular tachycardia (VT) ablation have not been thoroughly studied.

The Cardiac Electrophysiology Web Lab [PDF]

Biophysical Journal, 2015
Computational modelling of cardiac cellular electrophysiology has a long history, with many models now available for different species, cell types, and experimental preparations. This success brings with it a challenge: how do we assess and compare the underlying hypotheses and emergent behaviours, in order to choose a model as a suitable basis for a ...

Iron Overload Leading to Torsades de Pointes in β-Thalassemia and Long QT Syndrome [PDF]

, 2016
The authors present a unique case of torsades de pointes in a β-thalassemia patient with early iron overload in the absence of any structural abnormalities as seen in hemochromatosis.

Life‐Like Ferrous Oxide Microspheres from Kombucha

Advanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

Advanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

Hope in Miniature: The First Case of Implantation of a “Tiny Pacemaker” in Italy as a Successful Treatment for Congenital Atrioventricular Block in a Low Birth Weight Child

Case Reports in Cardiology
Congenital complete atrioventricular block (CAVB) is a rare cardiac condition occurring in approximately one in 15,000 to one in 22,000 live births. Maternal autoimmune diseases, with anti-ssA (Ro) and anti-ssB (La) antibodies implicated in 56%–90% of ...

Same-day discharge after atrial fibrillation ablation

Heliyon, 2023
Background: Atrial fibrillation (AF) catheter ablation has become an increasingly effective and safe strategy for the management of AF. With increased safety of catheter ablation, same-day discharge (SDD) is a potential way to minimize health care ...

Arrhythmogenic Right Ventricular Cardiomyopathy Caused by a Novel Frameshift Mutation

, 2016
Arrhythmogenic right ventricular cardiomyopathy is a rare cardiomyopathy that might be asymptomatic or symptomatic, causing palpations or syncope, and might lead to sudden cardiac death. It is recommended that physical exertion be reduced.
