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

description | 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.
The peQasus study is a large European multicenter study set up to assess safety, acute efficacy and outcomes of temperature-controlled HPSD based PVI. The primary endpoints were safety, efficacy and 12-months freedom from atrial tachyarrhythmias. Additionally, two strategies namely very HPSD (90W for 4 seconds) only and a hybrid approach (HPSD with maximum of 50W and vHPSD) were compared.
A total of 1,023 AF patients in 15 centers from 9 European countries received PVI with the QDOT. Complete PVI was successfully achieved in all patients. In 699/1023 (68.3%) the vHPSD only approach (vHPSD group) and in 324/(31.7%) patients the hybrid approach (hybrid group) was utilized. The mean procedure duration was 98.4±37.4 min (vHPSD: 88.2±34.9min, hybrid: 117.4±32.7min, p |
