High-power short-duration ablation
CTI ablation with electroanatomic navigation system using individual 25-40 W applications of unlimited duration until achieving in each application the minimum value of one of the currently accepted and used lesion markers: Ablation Index >500 at the anterior half of the CTI and >400 at the posterior half with de CARTO 3 system. Minimum contact force required is 5 grams. Maximum distance between applications must be 6 mm.
CTI ablation with electroanatomic navigation system using individual high power (90W) short duration (4 seconds) applications in a catheters' stable position with a minimum contact force of 15-30 g at the anterior half and 10-25 g at the posterior one. Maximum distance between applications is settled at 4 mm.
