Abstract：
Cryoballoon 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.
摘要：
冷冻球囊消融已被确立为肺静脉隔离的有效方法，并且最近已对其在持续性房颤患者的左心房顶部区域进行基质修饰的功效进行了研究。我们在此报告了第一个成功的左心房后壁隔离的病例，包括在持续性心房颤动患者中使用冷冻球囊进行屋顶线消融。右位心,和Situs倒置。冷冻球囊消融被证明是一种安全而直接的方法，可以沿着左心房顶部线和左心房后壁产生持久的损伤。即使在具有挑战性的解剖条件下。
