法国学者Hocini发现解剖指导下的环肺静脉消融可导致连续性组织学损伤,但并未造成完全性电学隔离。本研究选择了20例阵发性房颤患者,采用Carto标测系统在解剖指导下对肺静脉进行连续环形消融,达到消融终点(局部电压降低至0.1mV以下)后,通过环状电极标测发现44个肺静脉(55%)达到 Hocini, a French scholar, found that anatomically guided circumferential pulmonary vein ablation can lead to continuous histological damage without causing complete electrical isolation. In this study, 20 patients with paroxysmal atrial fibrillation were selected. Continuous circumferential ablation of the pulmonary veins under the guidance of anatomy was performed with Carto mapping system. After reaching the ablation end point (local voltage was reduced to 0.1mV or less) Forty-four pulmonary veins (55%) were achieved
