We investigated the impact of steerable sheaths on ablation CF, its consistency, and wide area circumferential ablation (WACA) line reconnection sites.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>Five thousand and sixty\u2010four ablations were analyzed across 60 patients undergoing first\u2010time ablation for persistent AF using a CF\u2010sensing catheter: 19 manual nonsteerable sheath (Manual\u2010NSS), 11 manual steerable sheath, and 30 robotic steerable sheath (Sensei, Hansen Medical Inc.) procedures were studied. Ablation CFs were higher in the steerable sheath groups for all left atrial ablations and also WACA ablations specifically (P\u00a0&lt;\u00a00.006), but less consistent per WACA segment (P\u00a0&lt;\u00a00.005). There were significant differences in the CFs around both WACAs by group: in the left WACA CFs were lower with Manual\u2010NSS, other than at the anterior\u2013inferior and posterior\u2013superior regions, and lower in the right WACA, other than the anterior\u2013superior region. There was a difference in the proportion of segments chronically reconnecting across groups: Manual\u2010NSS 26.5%, manual steerable sheath 4.6%, robotic 12% (P\u00a0&lt;\u00a00.0005). The left atrial appendage\/PV ridge and right posterior wall were common sites of reconnection in all groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Steerable sheaths increased ablation CF; however, there were region\u2010specific heterogeneities in the extent of increment, with some segments where they failed to increase CF. Steerable sheath use was associated with reduced WACA\u2010segment reconnection. It may be that the benefits of steerable sheath use in terms of higher CFs could be translated to improved clinical outcomes if regional weaknesses of this technology are taken into account during ablation procedures.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jce.12573","type":"journal-article","created":{"date-parts":[[2014,10,27]],"date-time":"2014-10-27T08:31:30Z","timestamp":1414398690000},"page":"266-273","source":"Crossref","is-referenced-by-count":15,"title":["Impact
