HRS 2021: GANGLIA-AF Trial
Author(s): Maria Min-Young Kim Added: 2 years ago
In this interview, Dr Maria Min-Young Kim (Imperial College Healthcare NHS Trust, London, UK) discusses the results of the GANGLIA-AF Trial, a study that aimed to determine the role of ectopy-triggering ganglionated plexus ablation (ET-GP) in the treatment of Atrial Fibrillation. Questions: 1. Please summarise the main aims, study design and endpoints of this trial? 2. What were your key… View more

Electrophysiology & Arrhythmia
Author(s): Jonathan W Waks , Mark E Josephson Added: 3 years ago
Atrial fibrillation (AF), the most common sustained arrhythmia, is a leading cause of stroke, and is associated with significant morbidity and mortality worldwide. Despite its frequency, clinical importance, and advances in technology and our knowledge of the molecular, ionic and physiological fundamentals of cardiac electrophysiology, our limited understanding of the mechanisms that initiate and… View more

Unmasking Adenosine: The Purinergic Signalling Molecule Critical to Arrhythmia Pathophysiology and Management
Author(s): Gareth DK Matthews , Andrew Grace Added: 3 years ago
The use of adenosine in cardiology is ubiquitous. From arrhythmia to coronary intervention to cardiac imaging, adenosine is an essential part of everyday practice because of its widespread effects on electrophysiology and the coronary vasculature. Electrophysiologists will be most familiar with adenosine for its use in terminating supraventricular tachycardias (SVTs) that are dependent on the… View more

Multimodality Imaging to Guide Ventricular Tachycardia Ablation in Patients with Non-ischaemic Cardiomyopathy
Author(s): Ling Kuo , Jackson J Liang , Saman Nazarian , et al Added: 3 years ago
Catheter ablation has been increasingly used as a treatment for refractory ventricular tachycardia (VT) in patients with non-ischaemic cardiomyopathy (NICM). However, ablation outcomes tend to be quite variable because of the heterogeneity of the aetiology for the NICM and associated VT substrate in these patients.1–3 Patients with NICM can be sub-classified based on specific genotypic and… View more

ACC.24: The Embo-Abl Study
Author(s): Kengo Kusano Added: 1 week ago
ACC.24 — We are joined by Dr Kengo Kusano (National Cerebral and Cardiovascular Center, JP) to discuss the findings from the Embo-Abl Study.Embo-Abl is a multicenter prospective randomized study which aims to compare the incidence of periprocedural cerebral embolisms caused by catheter ablation of atrial fibrillation (AF) between cryoballoon and radiofrequency ablation. 230 patients with AF from… View more

EHRA 22: Real-world Data on S-ICD in Heart Failure Patients
Author(s): Marco Schiavone Added: 2 years ago
In this short interview recorded at EHRA 2022, Dr Marco Schiavone (Luigi Sacco University Hospital, Milan, IT) outlines the findings of a real-world meta-analysis designed to assess the clinical outcomes of S-ICD in HF patients from the largest European Registry. Results suggest that over 2 years, there were no significant differences in appropriate and inappropriate shocks between patients with… View more

Electrophysiology & Arrhythmia
Author(s): Penelope A Boyden , Wen Dun , Bruno D Stuyvers Added: 3 years ago
Abnormalities in electrical rhythm were studied by Einthoven at the start of the 20th century. In the 1940s, studies by Bozler et al.1 described contractile signals that appeared to be ‘triggered’ heart beats. Today we use the term delayed afterdepolarisations (DADs) to refer to oscillations in voltage that follow a driven action potential. In the mid-1970s, progress was made when Lederer and… View more
