High-power, Short-duration Radiofrequency Ablation for the Treatment of AF
Author(s): Irum D Kotadia , Steven E Williams , Mark O’Neill Added: 3 years ago
AF is the most common sustained cardiac arrhythmia and radio­frequency is the dominant energy source used for atrial ablation. Owing to an ageing population and the increasing burden of cardiovascular disease, the prevalence of AF, particularly in developed countries, is increasing.1,2 With increasing prevalence comes additional financial burden.3 It is paramount that AF therapy is effective in… View more

Electrophysiology & Arrhythmia
Author(s): Dipen Shah Added: 3 years ago
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, is associated with increased risk of stroke and heart failure and is a significant global health challenge.1 Pharmacological treatments to restore sinus rhythm in patients with AF are associated with a considerable relapse rate,2,3 whereas nonpharmacological interventions, such as catheter ablation procedures, which isolate… View more

Electrophysiology & Arrhythmia
Author(s): Henry Chubb , Steven E Williams , John Whitaker , et al Added: 3 years ago
Interventional magnetic resonance imaging (MRI) is a growing field, and the strength of MRI guidance for procedures rests fundamentally in the high-contrast imaging of soft tissue structures. Combined with the avoidance of radiation exposure, the potential for functional assessment and the ability to exploit MR signals for calculation of the location of interventional instruments, it is clear… View more

EHRA 23: Conformable PVI Catheter for PVI
Author(s): Vivek Reddy Added: 1 year ago
EHRA 2023 — Dr Vivek Y Reddy (Mount Sinai Hospital, US) shares the details of a study looking at conformable PVI catheters for pulmonary vein isolation (PVI). The study investigates the use of a highly deformable mesh-like eight-french catheter that has recently received CE mark approval. The trial is ongoing at three centers. Questions: What's the research context or rationale? Describe the… View more

The Cryoballoon vs Irrigated Radiofrequency Catheter Ablation (CIRCA-DOSE) Study Results in Context
Author(s): Jason G Andrade , Atul Verma , Laurent Macle , et al Added: 3 years ago
AF is a common chronic, progressive disease, characterised by exacerbations and remissions. Over the past 10–15 years, multiple large-scale observational studies and randomised controlled trials have demonstrated that catheter ablation is superior to anti-arrhythmic drug (AAD) therapy in maintaining sinus rhythm and improving AF-related symptoms, exercise capacity and quality of life.1–7 The… View more

Electrophysiology & Arrhythmia
Author(s): Stephen P Page , Mehul Dhinoja Added: 3 years ago
Over the last 30 years, the role of catheter ablation for treating a wide range of arrhythmias has increased dramatically. The electrophysiological substrates of the more straightforward arrhythmias (such as atrio-ventricular reciprocating tachycardia and atrio-ventricular nodal re-entry tachycardia) have now been well defined and excellent long-term success rates can be achieved at minimal risk… View more

Cardiac MRI to Manage Atrial Fibrillation
Author(s): Yan Zhao , Lilas Dagher , Chao Huang , et al Added: 3 years ago
AF is a common arrhythmia in clinical practice, with a prevalence of 2.7–6.1 million that is expected to rise to 5.6–12 million by 2050 in the US alone.1,2 Patients with AF have an increased risk of stroke and mortality and a decreased quality of life.3 In addition, management of AF increases the cost of healthcare.4,5,6 The mechanisms of AF are complex and are associated with electric and… View more

Atrial fibrillation (AF) is the most common sustained arrhythmia in the clinical practice.1 The prevalence of the arrhythmia is progressively increasing in developed countries and moreover, it is expected to affect up to 12 million people only in the US by 2050.2 Antiarrhythmic drugs continue to represent the first-line of treatment in AF patients, either to restore sinus rhythm or to prevent… View more
