心房颤动 (AF)是临床上常见的心律失常 ,目前尚缺乏十分有效的治疗手段。近年来国内外文献表明肺静脉电隔离术 (PVI)能够明显改善AF患者的预后 ,揭开了AF治疗的新篇章 ,但随访观察AF再发率为 2 0 %左右 ,限制了此项技术在临床上的应用。在PVI方法学上影响AF复发率的因素涉及靶肺静脉的选择、Lasso环形标测电极大小的选择和解剖定位、术中对肺静脉电位的识别与记录、大头消融导管的选择以及对消融终点的判定等诸多方面 ,这些因素值得进一步研究和探讨以提高PVI成功率和降低AF复发率。
Atrial fibrillation (AF) is a common clinical arrhythmia, the current lack of a very effective treatment. In recent years, domestic and foreign literature shows that pulmonary vein isolation (PVI) can significantly improve the prognosis of patients with AF, opened a new chapter in the treatment of AF, but follow-up observation of AF recurrence rate of 20%, limiting the technology in clinical On the application. The factors influencing the recurrence rate of AF in PVI method include the selection of target pulmonary vein, the size and location of Lasso ring mapping electrode, the identification and recording of pulmonary venous potential in operation, the selection of bulk ablation catheter and the determination of ablation end point And many other aspects, these factors deserve further study and discussion to improve the success rate of PVI and reduce the recurrence rate of AF.
