This complaint is from a literature source.Reinsch n, füting a, buchholz j, ruprecht u, neven k.Influence of ablation index on the incidence of cardiac tamponade complicating pulmonary vein isolation.Herz.2021 sep;46(suppl 2):228-234.English.Doi: 10.1007/s00059-020-04988-y.Epub 2020 oct 7.Pmid: 33026484.Objective/methods/study data: the authors tried to hypothesize the use of ai reduces the incidence of ct.All af procedures between 10/2014 and 06/2019 were included.Three ablation groups were defined: group a, rf ablation with non-contact force (cf) catheter; group b, rf ablation with cf catheter; and group c, rf ablation with cf catheter using ai.All episodes of ct were analyzed.In total, 1222 consecutive af patients underwent pvi.Group a consisted of 100 (8%) procedures, while group b included 432 (35%) procedures and group c 690 (57%) procedures.The overall risk for ct in all patients was 2.1% (26/1222).The risk in group a was 2.9% (3/100), in group b 2.5% (11/432), and in group c 1.7% (12/690), including all 1222 patients in the analysis (p<0.05).Univariate analysis identified no further specific predictors for ct.With the exception of one patient (1/26; 3.8%), who needed surgical treatment, all ct could be successfully drained.Lot, model and catalog number are not available, but the suspected biosense device possibly associated with reported adverse events: 3.5-mm thermocool navistar® catheter.Other biosense webster devices that were also used in this study: carto 3.20-pole circular catheter (lasso).Visitag®( biosense webster, inc., (b)(4), usa).Non-biosense webster devices that were also used in this study: cyroballow group: decapolar electrode catheter, two fixed-curve sheaths (8.5 f sl1 fast-cath guiding introducer, st.Jude medical, minneapolis, mn, usa), 3.5- mm mapping and ablation catheter.Adverse event(s) and provided interventions (associated with ablation in the cf group): qty 26- cardiac tamponade- successful and uncomplicated pericardiocentesis performed in all patients.Qty 1- cardiac tamponade- needed surgical treatment.
