This complaint is from a literature source.The following literature cite has been reviewed: schlögl s, schlögl ks, bengel p, haarmann h, bergau l, rasenack e, hasenfuss g, zabel m.Contact force sensing manual catheter versus remote magnetic navigation ablation of atrial fibrillation: a single-center comparison.Heart vessels.2024 jan 8.Doi: 10.1007/s00380-023-02344-8.Epub ahead of print.Pmid: 38189924.Objective/methods/study data: background: data comparing remote magnetic catheter navigation (rmn) with manual catheter navigation in combination with contact force sensing (mcn-cf) ablation of atrial fibrillation (af) is lacking.The primary aim of the present retrospective comparative study was to compare the outcome of rmn versus (vs.) mcn-cf ablation of af with regards to af recurrence.Secondary aim was to analyze periprocedural risk, ablation characteristics and repeat procedures.Methods: retrospectively analyzed 452 patients undergoing a total of 605 ablations of af: 180 patients were ablated using rmn, 272 using mcn-cf.Results: except body mass index there was no significant difference between groups at baseline.After a mean 1.6 ± 1.6 years of follow-up and 1.3 ± 0.4 procedures, 81% of the patients in the mcn-cf group remained free of af recurrence compared to 53% in the rmn group (p < 0.001).After analysis of 153 repeat ablations (83 mcn-rf vs.70 rmn; p = 0.18), there was a significantly higher reconnection rate of pulmonary veins after rmn ablation (p < 0.001).In multivariable cox-regression analysis, rmn ablation (p < 0.001) and left atrial diameter (p = 0.013) was an independent risk factor for af recurrence.Procedure time, radiofrequency application time and total fluoroscopy time and fluoroscopy dose were higher in the rmn group without difference in total number of ablation points.Complication rates did not differ significantly between groups (p = 0.722).Conclusions: in retrospective comparative study, the af recurrence rate and pulmonary vein reconnection rate is significantly lower with more favorable procedural characteristics and similar complication rate utilizing mcn-cf compared to rmn.Table 3 note: the post procedural groin complications are associated with sheaths and the article identifies non-biosense webster sheaths used in the study.Pericardiocentesis after failed transseptal puncture are associated with transseptal sheath and needle that are not identified in the article.Lot, model and catalog number are not available, but the suspected biosense device possibly associated with reported adverse events: navistar thermocool rmt in the rmn group, thermocool smarttouch sf in mcn-cf group.Concomitant biosense webster devices that were used in this study: lasso mapping catheter, carto mapping system, smartablate generator concomitant non-biosense webster devices that were also used in this study: transseptal sl1 sheath (st.Jude) in rmn group, agilis sheath (st.Jude) in mcn-cf group, niobe ii (steriotaxis) magnetic navigation system in rmn group.Adverse event(s) and provided interventions possibly associated with unidentified navistar thermocool rmt ablation catheter in the rmn group in table 3: qty 2 postprocedural effusion after ablation (pericardial effusion) (recognized procedural complication).Adverse event(s) and provided interventions possibly associated with unidentified thermocool smarttouch sf ablation catheter in the mcn-cf group in table 3: qty 1 postprocedural effusion after ablation (pericardial effusion) (recognized procedural complication).Qty 2 phrenic nerve palsy (diaphragmatic paralysis) (recognized procedural complication).
