| Popis: | PURPOSE: The purpose of the study was to evaluate the impact of left atrial posterior wall isolation (LAPWI) in addition to pulmonary vein isolation (PVI) vs PVI alone, performed using CB-A, in patients with PAF on a midterm follow-up of 12 months. METHODS: Eighty consecutive patients indicated to index cryoballoon ablation (CB-A) for the treatment of drug resistant PAF were included. The first 50 (62.5%) underwent PVI only, and the following 30 patients (37.5%) underwent LAPWI + PVI. RESULTS: Acute isolation was achieved in all PVs in both groups. The LAPW was successfully isolated in 29 out of 30 (97%) patients; in the remaining patient, adjunct radiofrequency ablation was required. The total procedure time and the mean fluoroscopy time were significantly shorter in patients who underwent PV isolation only (p |
