Temperature-guided high and very high-power short duration ablation for atrial fibrillation treatment: the peQasus multicentre study.

ABSTRACT:

Aims

Temperature-controlled high-power short-duration (HPSD) radiofrequency catheter ablation for pulmonary vein isolation (PVI) utilizing a novel ablation catheter (QDOT Micro) with real-time assessment of catheter tip temperature aims for safer, more effective, and faster procedures.

Methods and results

The peQasus study is a large European multicentre study set up to assess safety, acute efficacy, and outcomes of temperature-controlled HPSD-based PVI. The primary endpoints were safety, efficacy, and 12-month freedom from atrial tachyarrhythmias. Additionally, two strategies namely very HPSD (90 W for 4 s) only and a hybrid approach (HPSD with maximum of 50 W and vHPSD) were compared. A total of 1023 AF patients in 15 centres from nine European countries received PVI with
