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 antrum 2 Electrically isolating all of the PVs at the level of the antrum 3 Avoiding risk of PV stenosis by ablating outside of the antrum 4 Minimizing risk of other complications, such as perforation and stroke, by direct visualization during transseptal access and radiofrequency (RF) ablation.
