有几种消融技术用于房颤消融，但对于哪种技术是最有效的，还没有普遍的共识。在我们的中心，我们已经开发了一种在其窦部分离肺静脉(PV)的技术。这项技术是由心内超声心动图(ICE)和环形(套索)导管标测。我们的技术是基于四个关键原则开发的：1.准确识别PV窦的真实边界2。电隔离鼻窦水平的所有静脉曲张。通过在窦腔外消融来避免门静脉狭窄的风险。在经鼻中隔进路和射频消融术中通过直接可视化将其他并发症(如穿孔和中风)的风险降至最低。
Several techniques are used for AF ablation, but no general consensus exists as to which technique is the most effective. At our center, we have developed a technique for isolating the pulmonary veins (PVs) at their antrum. The technique is guided by intracardiac echocardiography (ICE) and mapping with a circular (Lasso) catheter. Our technique was developed based on four crucial principles:1. Precisely identifying the true border of the PV antrum2. Electrically isolating all of the PVs at the level of the antrum3. Avoiding risk of PV stenosis by ablating outside of the antrum4. Minimizing risk of other complications, such as perforation and stroke, by direct visualization during transseptal access and radiofrequency (RF) ablation.
