Atrial Fibrillation
Conditions
Brief summary
The HELIOSTARTM catheter (Biosense Webster) is a new technology for pulmonary vein isolation (PVI) in atrial fibrillation (AF), combining radiofrequency (RF)-ablation and 3D-mapping visualization with the concept of single-shot-ablation device. This study evaluates the operator learning curve und procedural outcome during implementation of the HELIOSTARTM.
Detailed description
The first patients undergoing PVI by HELIOSTARTM at Heidelberg University Hospital are included in this prospective study. Procedures are performed by an operator proficient in CB-ablation. Procedural outcome was analyzed over the course of increasing experience with the device and in comparison to a previous cohort investigated during implementation of the Arctic FrontTM-cryoballoon (Medtronic).
Interventions
Local electrical isolation of PV ostia to prevent recurrence of AF due to ectopic PV-triggers
