Variant pulmonary venous anatomy is common and its pre-procedural recognition through cardiac imaging facilitates a personalized approach to ablation tailored to the individual patient. Close juxtaposition of the right and left pulmonary veins is an anatomic variation that serves as an ideal substrate for creation of a single box lesion set that concomitantly isolates the pulmonary veins and posterior wall. Isolation of the posterior wall may serve as an adjunctive ablative strategy in addition to pulmonary vein isolation that facilitates maintenance of sinus rhythm among patients with persistent atrial fibrillation.
变异的肺静脉解剖结构很常见，通过心脏成像在术前识别它有助于针对个体患者制定个性化的消融方法。左右肺静脉紧密相邻是一种解剖变异，它是创建单个盒状病变组的理想基础，该病变组可同时隔离肺静脉和后壁。除肺静脉隔离外，后壁隔离可作为一种辅助消融策略，有助于维持持续性房颤患者的窦性心律。
