title: Eccentric scar formation around a pulmonary vein after cryo-balloon ablation in a patient with atrial fibrillation: A case report.
abstract: The impact of a cryoballoon ablation is reported to be similar to that of a radiofrequency (RF) ablation in patients with atrial fibrillation. Delayed enhancement magnetic resonance imaging (DE-MRI) could visualize the scar region induced by the cryoballoon ablation as well as RF ablation. Cryoballoon ablation could induce extensive scar lesions around the PVs. However, the distribution of the scar lesions after the cryoballoon ablation has not been well discussed. We, herein, described a case with an eccentric scar distribution after cryoballoon ablation.
