Curative catheter ablation of atrial fibrillation has made some important advances during the last years toward a reproducible and effective procedure. Besides the role of the trigger to induce atrial fibrillation episodes by rapid burst from within the pulmonary veins (PVs), invasive electrophysiological studies could also demonstrate the importance of the close-by surrounding atrial myocardium to sustain atrial fibrillation. Meanwhile, new energies sources such as laser, ultrasound and cryothermia are used, next to the established ablation technology of radiofrequency current ablation, to apply lesions mostly around the PV ostia. With the magnetic navigation system, a new technology has entered the arena of catheter ablation of complex arrhythmia. By combining both three-dimensional mapping system and three-dimensional imaging ability, the system allows complete remote-controlled mapping (and ablation) of atrial fibrillation.
在过去几年中,心房颤动的根治性导管消融术在实现可重复且有效的手术方面取得了一些重要进展。除了肺静脉内快速爆发引发心房颤动发作的触发因素的作用外,侵入性电生理研究还能证明紧邻的周围心房心肌对维持心房颤动的重要性。同时,除了已确立的射频电流消融技术外,还使用了激光、超声和低温冷冻等新能源来在肺静脉口周围形成损伤。随着磁导航系统的出现,一项新技术进入了复杂心律失常导管消融领域。通过结合三维标测系统和三维成像能力,该系统能够对心房颤动进行完全远程控制的标测(和消融)。
