“…We thank Dr Shah and colleagues for their interest, analysis of the presented data and comments related to our paper. 1 Circumferential pulmonary vein isolation using 8 mm tip catheter is still currently used in our institution for some patients due to economic reasons, so we can provide atrial fibrillation (AF) ablation for a portion of the population for whom there is no private insurance available, with adequate safety and results (recurrence rate in this series was 15.6% in a follow-up of 11 ± 5 months). 2 Those catheters have two temperature sensors, thus reducing the risk of clot formation on the tip of the catheter.…”
