Summary

BEAT AF is a randomized controlled trial aiming to demonstrate that pulsed field energy is faster, more effective and safer (tissue selectivity) than RF for paroxysmal AF ablation

Detailed description

Atrial fibrillation (AF), the most common arrhythmia, accounts for 1/3rd of Cardiovascular expenses, with over 10 millions affected in Europe. In addition to significant impact on quality of life, AF exposes patients to stroke, heart failure, dementia and death. AF is the most commonly ablated arrhythmia. The Pulmonary Vein Isolation (PVI) is the cornerstone of AF ablation, preventing recurrences, especially in patients with paroxysmal AF. Catheter ablation of AF uses either radiofrequency (RF) or cryothermal (cryo) energy. Common to these thermal energy sources is their reliance on time-dependent conductive heating/cooling and the fact that these modalities ablate all tissue types indiscriminately. The ablation procedure remains long, requires skills and expertise, and has a limited success rate, mostly because of non-durable lesions after PVI implying frequent redo procedures. And these energies are associated with rare but severe complications due to their thermal nature. The goal of BEAT AF is to disrupt AF ablation by achieving durable PVI with permanent, coalescent and transmural ablation lesions using Pulsed Electric Field (PEF) energy. PEF is non-thermal and creates nanoscale pores in cell membranes. Cardiac cells are highly sensitive to PEF unlike phrenic and oesophageal cells. BEAT AF aims to demonstrate that PEF ablation is faster, more effective and safer (tissue selectivity) than RF ablation to treat paroxysmal AF. For this purpose, a randomized clinical trial will be conducted to provide first comparative evidence of the superiority of PEF over RF on the rate of 1-year recurrence for paroxysmal AF. The BEAT AF consortium gathers 9 European renowned clinical centres (France, Czech Republic, Germany, Austria, Belgium) to contribute to decrease the huge burden of AF.
