The following article titled, "usefulness of the steerable sheath for atrial fibrillation ablation" was presented on at the (b)(6)."one hundred four patients with af (84 cases paroxysmal, 20 cases persistent af) underwent left atrial abl from march 2015 to december 2016.The ablation catheter was handled with the steerable sheath (agillis nxt, st jude medical) and circumferential mapping catheter was placed with fixed curve sheath.Mapping and abl were performed under guidance of 3d mapping system.There was a tendency of correlation between the study number and total procedure time, pv isolation time, total fluoroscopic exposure does, and mapping time (p=0.0028).There were no complications such as cardiac tamponade or stroke.1 patient had phrenic nerve palsy and 2 patients had severe pulmonary vein stenosis.Af free rate at chronic phase (8.6±5.1 month after ablation) was 84.7%.Pv isolation time was reduced with steerable sheath catheter navigation technique, mapping time or additional ablation time were also reduced by the ablation number.So one of the reason of reducing total procedure time was getting skilled operators and staff of the laboratory.".
