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

AFSymposium 24: EASY AF: Esophagus Deviation During Radiofrequency Ablation of AF
Author(s): Emile Daoud Added: 2 months ago
AF Symposium 2024 — Dr Emile Daoud (Chief Medical Officer of S4 Medical) joins us to talk about the data from the EASY AF study (NCT04659213).This randomized, controlled study investigated the use of an esophageal deviating device versus no device. The study showed that the use of the esophageal deviating device (S4 Medical) resulted in a significantly lower rate of ablation-related esophageal… 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

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

Catheter ablation is an effective strategy to maintain sinus rhythm in patients with symptomatic atrial fibrillation (AF), which has evolved from a highly specialised technique to a first-line therapy.1–3 The cornerstone of ablation is pulmonary vein isolation (PVI).4 Over the last decade, ablation devices have undergone technical improvements, aiming for better lesion durability and ablation… View more

Advanced catheter-based technologies employed for the ablation of symptomatic atrial fibrillation (AF) have revolutionised the management of this common sustained arrhythmia. In the late 1990s, premature depolarisations originating from the myocardial sleeves within the pulmonary veins were recognised to initiate AF. This landmark discovery rendered pulmonary vein isolation (PVI) as the… View more
