Adenosine-guided radiofrequency catheter ablation of atrial fibrillation: A meta-analysis of randomized control trials

Journal of Arrhythmia, 2017
Background: The prognostic significance of adenosine-mediated dormant pulmonary vein conduction, and whether such dormant conduction should be eliminated, remains controversial.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Molecular Basis for Activation to Inhibition Switching in Kv7.2 Channel Modulators

Angewandte Chemie, EarlyView.
The paper describes the serendipitous discovery of chemical manipulation allowing the activator‐to‐inhibitor switching in Kv7.2 channel modulators. The molecular determinants driving this switch have been rationalized by multidisciplinary investigation encompassing synthetic and analytical chemistry, in silico methods, cryo‐EM analysis ...

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 ...

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 ...
