Despite the mounting evidence about AT mechanisms and types, data are scarce regarding the conduction properties as well as the functional characteristics of the atrial substrate during sinus rhythm, which plays a role in the maintenance of tachycardia. We sought to evaluate the relationship between the functional substrate mapping (FSM) characteristics of the right atrium (RA) and the critical isthmus (CI) of re-entrant ATs in patients with underlying atrial scar. Patients with a history of right AT who underwent catheter ablation with three-dimensional mapping were retrospectively enrolled. A voltage map and isochronal late activation map were created during the sinus/paced rhythm using multielectrode catheters to detect deceleration zones (DZs). Subsequently, AT was induced with programmed stimulation, and activation mapping was performed to detect the CI of the tachycardia. Atrial tachyarrhythmia (ATa) recurrence was defined as the detection of atrial fibrillation or AT (≥30 s) during follow-up. A total of 24 patients (mean age, 46 ± 15 years; 13 [54%] women) with right AT were included. A total of 36 ATs were mapped (16 [44.4%] localized re-entry, 20 [55.6%] macro-re-entry). Atrial low-voltage zones composed 23.3% ± 13.0% of the total RA. The mean values of bipolar voltage, electrogram duration, and conduction velocity during sinus rhythm corresponding to the CI of ATs were 0.18 ± 0.10 mV, 121.7 ± 29.4 ms, and 0.06 ± 0.04 m/s, respectively. The total number of DZs per chamber was 1.1 ± 0.3, with all being located in the low-voltage zone (<0.5 mV) detected by high-density mapping. All CIs of non-cavotricuspid isthmus (CTI)-dependent re-entry were co-localized with DZs detected during FSM. The positive predictive value of DZs to detect the CI of inducible ATs was 80.8%. During a mean follow-up of 11.7 ± 8.1 months, freedom from atrial tachyarrhythmias was 87.5%. Although CTI-dependent macro-re-entry is the most common mechanism in patients with RA scar, our findings demonstrated the relevance of FSM to predict non-CTI-dependent ATs. Conduction slowing manifested as DZs with continuous-fragmented signal morphology may guide ablation strategy tailoring in the case of underlying RA scar.</p>","PeriodicalId":36299,"journal":{"name":"Journal of Innovations in Cardiac Rhythm Management","volume":"16 7","pages":"6374-6384"},"PeriodicalIF":0.0,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12320912/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144790170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the data compiled from different meta-analyses in an umbrella review. We investigated the anticoagulation efficacy of direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) in patients with AF and BPVR. A comprehensive search of the Cochrane Database of Systematic Reviews, EMBASE, and PubMed was completed to find papers published up until June 2024 that could be included in this umbrella review. Randomized controlled trials (RCTs) and retrospective observational/cohort studies were primarily identified as the foundation of meta-analyses and peer-reviewed systematic reviews. The quality of the included publications was determined using the AMSTAR 2 tool and the Cochrane Collaboration's risk-of-bias tool, while the overall certainty of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. A total of 20 systematic reviews and meta-analyses of RCTs and observational studies were included in this umbrella review. Among the primary outcomes, the pooled analysis exhibited a significant reduction in all-cause mortality (risk ratio [RR], 0.95; 95% confidence interval [CI], 0.91-1.00; <i>P</i> = .05; <i>I</i>2 = 0%), risk of major/life-threatening bleeding (RR, 0.73; 95% CI, 0.66-0.82; <i>P</i> ≤ .00001; <i>I</i>2 = 66%), and stroke/thromboembolism (RR, 0.74; 95% CI, 0.67-0.82; <i>P</i> = .00001; <i>I</i>2 = 0%) in patients who were administered DOAC pharmacotherapy as compared to VKAs.

Secondary outcomes such as intracranial bleeding, any bleeding, and minor or clinically insignificant bleeding all showed a significantly decreased risk in the DOAC group versus the VKA group. Only two outcomes revealed an increased risk of cardiovascular events and risk of ischemic stroke in patients who received DOACs; however, these outcomes were statistically insignificant.

We sought to evaluate the impact of a practice-wide switch from RVP to LBBAP. We switched practice from RVP to primarily LBBAP at our center in 2020. A retrospective review was conducted to compare patients who underwent LBBAP from 2020-2023 with controls who underwent RVP from 2018-2019. The LBBAP (n = 288; age, 73.3 ± 10.7 years; left ventricular ejection fraction [LVEF], 56.9% ± 11.4%) and RVP (n = 172) groups were similar in terms of age, body mass index, hypertension, diabetes, and LVEF. The LBBAP group as compared to the RVP group had fewer women (38% vs. 51%; <i>P</i> = .006) and longer intrinsic conducted QRS durations (117 ± 28 vs. 110 ± 30 ms; <i>P</i> = .04). LBBAP devices required longer implant (102 vs. 67 min) and fluoroscopy (9.3 vs. 6.9 min) times but resulted in shorter paced QRS durations (122 ± 20 vs. 145 ± 24 ms; all <i>P</i> < .0001).

A comprehensive search was conducted across PubMed, Google Scholar, and Embase to identify relevant studies comparing RMN and MCN for AF ablation. Statistical pooling was done using Review Manager 5.4.1 (Cochrane Collaboration, London, UK). The Newcastle-Ottawa scale was used for the evaluation of bias in observational studies. We evaluated the robustness of the evidence following the guidelines outlined by the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) working group. The primary outcomes of the study included freedom from AF, procedure time, fluoroscopy time, and total complication rate in patients undergoing AF ablation either using the RMN or MCN technique. A total of 22 studies involving 5361 patients were included in the meta-analysis.
