Summary

This study is testing a new device called the VARIPULSE catheter system to treat persistent atrial fibrillation, a type of irregular heartbeat. The device uses pulsed field ablation to isolate specific heart veins and may be combined with a procedure to close off a heart pouch to reduce stroke risk. About 920 participants will be followed to see if the treatment is safe and effective over time.
