Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There is a need to compare the efficacy of PVI versus PVI plus catheter ablation, which includes ablation of complex fractionated atrial electrograms (CFAE) and linear lesions in the same procedure. If it is found that the PVI alone is as effective as PVI plus catheter ablation of CFAE and linear lesions, it may reduce the need for catheter ablation.
