NCT04855890

Brief Summary

Pulmonary vein isolation (PVI) using the cryoballoon has been proven equal to RF-PVI and is widely used. High Power Short Duration Ablation in RF-PVI has been successfully tested in several trials. Prospective data comparing both strategies is lacking. This trial will compare acute success rates, safety and foremost long-term outcome of two different PVI strategies (HPSD-PVI vs. cryo-PVI).

Study Arms (2)

Cryo-Ablation

ACTIVE COMPARATOR

Cryo-Balloon (Arctic Front Advance ProTM, Medtronic, Minneapolis, MN, USA) will be advanced to the LA and navigated to the PV's using an inner-lumen circular mapping catheter (Achieve AdvanceTM, Medtronic, Minneapolis, MN, USA). After confirming complete PV sealing by the CB using occlusion angiograms cryothermal energy will be applied for min 120 seconds aiming at PV isolation of all PV's according to the clinical standard.

Procedure: Ablation

High Power Short Duration-Ablation

ACTIVE COMPARATOR

A detailed electroanatomical map of the left atrium during sinus rhythm will be acquired using Ensite (Abbott, St. Paul, MN, USA). Upon completion of the LA map, a second transseptal puncture will be performed in order to insert an ablation catheter. To achieve antral PVI irrigated radiofrequency current ablation will be performed using a power of 70W and a flush rate of 8-30ml/min with a duration of 5 seconds for the anterior and 7 seconds for the posterior LA. Ablation catheters used will contain Flexibilty (Abbott, St. Paul, MN, USA) and TactiFlex (Abbott, St. Paul, MN, USA).

Procedure: Ablation

Interventions

AblationPROCEDURE

The ablation procedure will be performed during deep sedation using midazolam, fentanyl and a continuous infusion of propofol. Vital parameters will be monitored. For catheter access three 8F sheaths will be inserted into the femoral veins. A multipolar diagnostic catheter will be placed in the coronary sinus. Single transseptal puncture and insertion of a 8.5 F transseptal sheath or 12F Cryo-Sheath (FlexCath AdvanceTM, Medtronic, Minneapolis, MN, USA) will be followed by PV angiographies. Before or shortly after transseptal puncture unfractionated heparin will be repeatedly administered to maintain an activated clotting time between 250 and 400s.

Model Details: The present study is a mono-center prospective randomized study enrolling 170 patients with PAF and no prior Ablation for AF.

Group B: High-Power-Short-Duration PVI will be performed using HPSD RF-ablation. (70W over 5s posterior and 7s anterior) Catheter ablation procedures will be performed with commercially available devices including 3D mapping systems (EnSite, Abbott) and irrigated radiofrequency current (RFC) ablation or cryothermal balloon ablation (Arctic Front Advance Pro, Medtronic).
