Event Description

This complaint is from a literature source.The following literature cite has been reviewed mueller j, nentwich k, ene e, berkovitz a, sonne k, chakarov i, barth s, waechter c, behnes m, akin i, halbfass p, deneke t.Radiofrequency ablation of atrial fibrillation-50 w or 90 w.J cardiovasc electrophysiol.2022 dec;33(12):2504-2513.Doi: 10.1111/jce.15681.Epub 2022 oct 8.Pmid: 36124396.Objective and methods: background: this study sought to evaluate the short and midterm efficacy and safety of the novel very high power very short duration (vhpvsd) 90 w approach compared to hpsd 50 w for atrial fibrillation (af) ablation as well as reconnection patterns of 90 w ablations.Methods and results: consecutive patients undergoing first af ablation with vhpvsd (90 w; predefined ablation time of 3 s for posterior wall ablation and 4 s for anterior wall ablation) were compared to patients using hpsd (50 w; ablation index-guided; ai 350 for posterior wall ablation, ai 450 for anterior wall ablation) retrospectively.A total of 84 patients (67.1 ± 9.8 years; 58% male; 47% paroxysmal af) were included (42 with 90 w, 42 with 50 w) out of a propensity score-matched cohort.90 w ablations revealed shorter ablation times (10.5 ± 6.7 min vs.17.4 ± 9.9 min; p =.001).No major complication occurred.90 w ablations revealed lower first pass pvi rates (40% vs.62%; p =.049) and higher af recurrences during blanking period (38% vs.12%; p =.007).After 12 months, both ablation approaches revealed comparable midterm outcomes (62% vs.70%; log-rank p =.452).In a multivariable cox regression model, persistent af (hazard ratio [hr]: 1.442, 95% confidence interval [ci]: 1.035-2.010, p =.031) and increased procedural duration (hr: 1.011, 95% ci: 1.005-1.017, p =.001) were identified as independent predictors of af recurrence during follow-up.Cardioversion was performed when af persisted during voltage mapping.Conclusions: af ablation using 90 w vhpvsd reveals a similar safety profile compared to 50 w ablation with shorter ablation times.However, vhpvsd ablation was associated with lower rates of first-pass isolations and increased af recurrences during the blanking period.After 12 months, 90 w revealed comparable efficacy results to 50 w ablations in a nonrandomized, propensity-matched comparison.Lot, model and catalog number are not available, but the suspected biosense webster device possibly associated with reported adverse events: thermocool smart-touch stsf used in hpsd group at 50w.Qdot microused for pvi group at 90w.Lasso used in all study groups.Other biosense webster devices that were also used in this study: rf generator (ngen).Smartblate generator.Qmode plus.Carto 3.Non-biosense webster devices that were also used in this study: agilis sheath (abbott).Adverse event(s) and interventions: in the thermocool stsf/lasso 50w group: 14 pericardial effusions- no treatment provided.6 implanted pacemakers to treat persistent af during voltage mapping.35 esophageal lesions- no treatment specified.In the qdot/lasso 90 w group: 1 pericardial effusion- no treatment provided.1 implanted pacemaker to treat persistent af during voltage mapping.1 esophageal lesion- no treatment provided.
