Efficacy Comparison of High and Very High Power Short Duration Pulmonary Vein Isolation

Objective: To evaluate the long-term durability of PVI performed with 90W and 50W (QDot catheter). Primary hypothesis: Pulmonary vein isolation performed with 90W (QMODE+) and inter-tag distance \18 years, willingness to sign informed consent form. Exclusion criteria: Long-standing persistent AF, active malignancy, contraindication for anticoagulant therapy, life expectancy \<1 year, valvular AF, hyperthyroidism. Endpoints: At repeat procedure, a high density left atrial map will be created with PentaRay or if available OctaRay catheter to evaluate the durability of the PVI. Primary endpoint will be pulmonary vein reconnection.
