    AbstractCryoballoon ablation has been established as an effective method for pulmonary vein isolation and has recently been investigated for its efficacy of substrate modification on the left atrial roof area in patients with persistent atrial fibrillation. We herein report the first successful case of left atrial posterior wall isolation including roof line ablation using cryoballoons in a patient with persistent atrial fibrillation, dextrocardia, and situs inversus. Cryoballoon ablation proved to be a safe and straightforward approach to create lasting lesions along the left atrial roof line and left atrial posterior wall, even under challenging anatomical conditions.
