Brief Summary

The goal of this clinical trial is to compare two ablation techniques to treat patients with persistent atrial fibrillation (irregular and often very rapid heart rhythm). An ablation is a procedure during which some scars are made on the inside of the heart to break up the electrical signals that cause the irregular heartbeat. In this trial researchers will compare a new technique, which uses tiny electric shocks to make the scars, to the standard technique, which uses heat. The main question the trial aims to answer is: • Does the new technique work as well as the standard technique to prevent the irregular heartbeat from returning within one year of the procedure? Participants will: * Undergo an ablation with either the new or the standard technique * Visit the hospital 1, 3, 6, 9 and 12 months after the procedure for a check-up * Wear a device to register their heart rhythm for 24 hours before the 3 month visit and for 72 hours before the 6, 9 and 12 month visit * Record their heart rhythm at home every week * Complete a questionnaire 3, 6, 9 and 12 months after the procedure

Eligibility Criteria

Inclusion Criteria: * Symptomatic persistent atrial fibrillation (AF) despite a first PVI. Persistent AF is defined as the presence of AF lasting ≥7 days (i.e. in case of new onset AF one has to wait for 7 days) Exclusion Criteria: * Persistent AF lasting ≥ 12 months * Advanced valvular heart disease * Left atrial (LA) volume \>150mL * LA diameter (PS-LAX) \>60mm * Septal wall diameter \>15mm * Life expectancy \<1 year * Weight \>150 kg * Any contra indication to catheter ablation
