ESC 23: The SurHyb Trial
Author(s): Alan Bulava Added: 7 months ago
ESC 2023 — Dr Alan Bulava (Ceske Budejovice Hospital and University of South Bohemia, CZ) joins us in this succinct interview to discuss the findings from the SurHyb trial. The SurHyb study was a prospective, open-label-multicentre randomized trial. The study aimed to evaluate CryoMaze surgery alone, as compared to CryoMaze followed by radiofrequency catheter ablation 3-months post-surgery. … View more

Electrical Remodelling Evidence Supporting Atrial Remodelling The concept of electrical remodelling was first introduced in 1995 simultaneously by Wijffels et al.1 and Morillo et al.2 who demonstrated that once sustained atrial fibrillation (AF) was induced in goats, or rapid atrial pacing was performed in dogs, physiological changes occurred that favoured the maintenance of AF.3 This led to the… View more

Catheter ablation is more effective than pharmacological therapy for the secondary prevention of patients with paroxysmal1,2 and persistent3,4 atrial fibrillation (AF) and has an emerging role in the primary prevention of paroxysmal AF.5,6 Nevertheless, in randomised clinical trials (RCTs) its success in treating patients with paroxysmal AF is 40–60% for a single procedure and 70% for multiple… View more

Catheter-based ablation of atrial fibrillation (AF) is an established treatment option for symptomatic patients who are refractory to drug-based treatment, as implemented in the latest guidelines for the management of AF.1 The accepted and recommended cornerstone of all ablation strategies for AF is electrical isolation of the pulmonary veins (PV).2 However, in addition to PV isolation (PVI),… View more

The cornerstone of AF is electrical isolation of the pulmonary veins (PV). In patients with non-paroxysmal AF, PV isolation alone is insufficient, and one needs to modify the atrial arrhythmogenic substrate. AF ablation is now a common procedure and mostly performed using a transvenous, endocardial approach with catheters. For patients with persistent AF however, this procedure is not sufficient… View more

ACC 23: The PULSED AF Trial
Author(s): Atul Verma Added: 1 year ago
ACC.23/WCC - Principal Investigator, DrAtul Verma (McGill University Health Centre, CA) joins us on-site at ACC's 2023 Scientific Sessions to outline the findings of the PULSED-AF Trial(Medtronic Cardiac Rhythm and Heart Failure) (NCT04198701). In this prospective, multicenter study, 421 patients with persistent atrial fibrillation (AF) were treated with the Medtronic PulseSelect Pulsed Field… View more

Adecade after its first description as ‘the electrophysiological substrate’ of atrial fibrillation,1 mapping complex fractionated atrial electrogram (CFAE) as an ablation target for atrial fibrillation (AF) remains highly controversial. Early high-density mapping studies of induced AF in humans revealed distinct mechanisms that underlie electrogram fractionation: collision areas of distinct… View more
