Background

Persistent atrial fibrillation (AF) may require extensive ablation strategies. Left atrial posterior wall isolation (LAPWI) might address potential substrates for recurrence during pulsed-field ablation (PFA).

Objective

This meta-analysis aimed to investigate the feasibility and effectiveness of LAPWI in addition to pulmonary vein isolation (PVI) using a pentaspline catheter in PFA for AF.

Methods

Comprehensive search was conducted using PubMed, SCOPUS, ScienceDirect, and EuropePMC for studies reporting LAPWI+PVI using a pentaspline catheter in PFA ablation for AF. The primary outcome was atrial tachyarrhythmia (ATa) recurrence, defined as AF/atrial flutter/atrial tachycardia after blanking period.

Results

There were 882 patients from 7 studies. The success rate of LAPWI was 100% using mean/median of 16 to 20 added PFA applications with no reported acute left atrial posterior wall reconnection and esophageal complications. In mean follow-up of 240 ± 91 days, ATa recurrence was 21% (95% CI 13%–29%; I² = 84.8%) in the LAPWI+PVI group. Meta-regression analysis showed that age, left ventricular ejection fraction, and repeat procedure did not significantly influence ATa recurrence (P > .05). Each 1-mm increase in left atrial diameter, increases the chance of ATa recurrence by 6% (R² = 100%, P < .001, I² = 0%). Meta-analysis showed no difference in terms of ATa recurrence among LAPWI+PVI patients compared with those without LAPWI (odds ratio 0.78, 95% confidence interval 0.50–1.21, P = .27; I² = 0%, P = .86). Procedure time and fluoroscopy time did not significantly differ (P > .05).

Conclusion

LAPWI using a pentaspline catheter during PFA was feasible and did not prolong the procedure/fluoroscopy but did not reduce ATa recurrence. LAPWI may be considered during PFA, although the benefit is uncertain.

背景持续性心房颤动（房颤）可能需要广泛的消融策略。本荟萃分析旨在研究在脉冲场消融（PFA）治疗房颤时，除使用五线导管进行肺静脉隔离（PVI）外，使用左心房后壁隔离（LAPWI）的可行性和有效性。方法通过PubMed、SCOPUS、ScienceDirect和EuropePMC进行全面检索，以了解在房颤的PFA消融中使用五线导管进行LAPWI+PVI的研究报告。主要结果是房性心动过速（ATa）复发，定义为空白期后的房颤/房扑/房性心动过速。使用平均/中值 16 至 20 次的额外 PFA 应用，LAPWI 的成功率为 100%，无急性左房后壁重接和食管并发症的报道。在平均 240 ± 91 天的随访中，LAPWI+PVI 组的 ATa 复发率为 21% (95% CI 13%-29%; I2 = 84.8%)。元回归分析表明，年龄、左室射血分数和重复手术对 ATa 复发无明显影响（P > .05）。左心房直径每增加 1 毫米，ATa 复发几率增加 6%（R2 = 100%，P < .001，I2 = 0%）。Meta 分析表明，LAPWI+PVI 患者的 ATa 复发率与未进行 LAPWI 的患者相比没有差异（几率比 0.78，95% 置信区间 0.50-1.21，P = 0.27；I2 = 0%，P = 0.86）。手术时间和透视时间无明显差异（P >.05）。结论在 PFA 期间使用五针导管进行 LAPWI 是可行的，不会延长手术/透视时间，但不会减少 ATa 复发。在 PFA 期间可考虑进行 LAPWI，但其益处尚不确定。

Background

Myotonic dystrophy type 1 (DM1) is associated with progressive conduction disease. Furthermore, DM1 patients are at risk ventricular arrhythmias (VAs), although prediction remains difficult. The 2022 Heart Rhythm Expert Consensus Statement gives a IIb recommendation to the use of electrophysiology study (EPS) to risk-stratify patients for VAs. The utility of EPS in predicting the development of VAs, however, has not been explored in this patient population.

Objective

The study sought to examine the natural history of DM1 patients with positive and negative ventricular stimulation (v-stim) during EPS.

Methods

Patients with a history of DM1 undergoing EPS with associated v-stim from 2008 to present were retrospectively identified.

Results

From 2008 to 2022, 26 consecutive DM1 patients presented for EPS with v-stim. Four v-stim protocols were positive for sustained or hemodynamically significant ventricular tachycardia (VT), one of which was induced with 600 doubles, the others with triple extrastimuli. A total of 22 of 26 subjects received a device implant, with 18 receiving permanent pacemakers and 4 implantable cardioverter-defibrillators. All 4 of the patients with positive v-stims underwent ICD implantation. After a mean of 5.7 years of follow-up, 7 patients had sustained VT, 6 of whom had negative v-stims. Of the 4 patients with positive v-stims, only 1 developed sustained VT in follow-up. Other than baseline QT interval at time of EPS, no baseline characteristics were significantly different between patients with and without subsequent VT.

Conclusion

In this single center, v-stim in DM1 patients did not predict clinical VAs, as a vast majority of DM1 patients who developed VAs had negative v-stims.

背景1型肌营养不良症（DM1）与进行性传导疾病有关。此外，DM1 患者还存在室性心律失常（VAs）的风险，但预测仍很困难。2022 年《心脏节律专家共识声明》（The 2022 Heart Rhythm Expert Consensus Statement）建议使用电生理学研究（EPS）对室性心律失常患者进行风险分级，建议等级为 IIb。方法回顾性鉴定 2008 年至今接受 EPS 并伴有 v-stim 的 DM1 患者。结果从 2008 年到 2022 年，连续有 26 例 DM1 患者接受 EPS 并伴有 v-stim。四项v-stim方案对持续性或血流动力学显著性室性心动过速（VT）呈阳性反应，其中一项用600倍频诱导，其他则用三倍外刺激诱导。26 名受试者中共有 22 人接受了设备植入，其中 18 人接受了永久起搏器，4 人接受了植入式心律转复除颤器。所有 4 名 V-stims 阳性患者都接受了 ICD 植入术。在平均 5.7 年的随访后，7 名患者出现持续 VT，其中 6 名患者的 v-stims 呈阴性。在 4 名 v-stims 呈阳性的患者中，只有 1 人在随访期间出现持续性 VT。除 EPS 时的基线 QT 间期外，随后出现 VT 和未出现 VT 的患者的基线特征无显著差异。

Background

Several reports exist of an acquired exercise-induced arrhythmogenic cardiomyopathy. Little is known about myocardial disease progression and arrhythmia prediction in this population.

Objective

The study sought to explore the evolution of myocardial function and structure and its relation to incident life-threatening ventricular arrhythmias (VA), to identify markers of impending events.

Methods

We included athletes (individuals with exercise doses >24 metabolic equivalent of task hours per week, >6 consecutive years, participating in organized and competitive sports) who had VA, absence of family history and known genetic variants associated with cardiac disease, and no other identified etiology, in a tertiary referral single-center, longitudinal cohort study of patients with exercise-induced arrhythmogenic cardiomyopathy (EiAC). Evolution of myocardial function and structure was assessed by repeated echocardiographic examinations during long-term follow-up. Life-threatening VA were assessed at baseline and during long-term follow-up.

Results

Forty-one EiAC patients (15% women, age 45 ± 13 years) were followed for 80 (interquartile range 48–115) months. There were no changes in myocardial function or structure in the overall population during follow-up. We observed high incidence rate and high recurrence rate of life-threatening VA in EiAC patients. Subtle deterioration of right ventricular function was strongly associated with subsequent first-time VA (odds ratio 1.12, 95% confidence interval 1.01–1.25, P = .031, per 1% deterioration of right ventricular free wall longitudinal strain).

Conclusion

There were no clear changes in myocardial function or structure during follow-up in the overall population, but there was a high incidence rate and high recurrence rate of life-threatening VA. Subtle right ventricular deterioration by free wall longitudinal strain was a strong predictor of impending first-time life-threatening VA during follow-up.

背景关于后天运动诱发心律失常性心肌病的报道不胜枚举。本研究旨在探讨心肌功能和结构的演变及其与危及生命的室性心律失常（VA）事件的关系，以确定即将发生事件的标志物。方法我们在一项针对运动诱发心律失常性心肌病（EiAC）患者的三级转诊单中心纵向队列研究中，纳入了患有室性心律失常、无家族史、与心脏病相关的已知基因变异且无其他已确定病因的运动员（每周运动量相当于24个代谢任务小时，连续6年参加有组织的竞技运动）。在长期随访期间，通过重复超声心动图检查评估了心肌功能和结构的变化。结果对 41 名 EiAC 患者（15% 为女性，年龄为 45 ± 13 岁）进行了 80 个月（四分位数区间为 48-115 个月）的随访。在随访期间，所有患者的心肌功能和结构均无变化。我们观察到，EiAC 患者中危及生命的 VA 发生率高，复发率也高。右心室功能的细微恶化与随后的首次 VA 密切相关（几率比 1.12，95% 置信区间 1.01-1.25，P = 0.031，右心室游离壁纵向应变每恶化 1%）。随访期间，右心室游离壁纵向应变的细微恶化是预测即将发生的首次危及生命的VA的有力因素。

Atrial fibrillation (AF) and stroke are prevalent conditions worldwide, and the AF burden is expected to concentrate in low- and middle-income countries like Brazil. The National Institute for Health and Care Excellence–funded Global Health Research Group on Atrial Fibrillation Management (GHRG-AF) had a Brazilian arm that addressed AF epidemiology and care in Brazil. GHRG-AF analyzed data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a long-term cohort of 15,105 middle-aged adults in Brazil, focused on cardiovascular disease and diabetes. Additionally, the GHRG-AF used data from the Brazilian Study of Stroke Mortality and Morbidity (EMMA) study to understand AF impact on this cohort of 1863 stroke survivors, all admitted to a community hospital. The GHRG-AF also surveyed healthcare practices and the pathways of individuals who live with AF, interviewing health professionals and patients treated in different healthcare units in São Paulo. Despite these multiple approaches, those data were restricted to individuals living in large urban centers. Approximately 70% of the Brazilian territory comprises sparsely populated cities (<10 inhabitants/km²), which, as a group, are home to 15 million individuals. In a new step, the GHRG-AF collaborators aim to improve cardiovascular research capacity in distant locations of the Brazilian Amazon, develop patient-centered protocols, empower community health agents in the region, and intensify collaboration with other research groups in remote parts of the country.

心房颤动（房颤）和中风是全球普遍存在的疾病，预计房颤负担将集中在巴西等中低收入国家。由美国国家健康与护理卓越研究所资助的心房颤动管理全球健康研究小组（GHRG-AF）在巴西设有分支机构，负责研究巴西的心房颤动流行病学和护理问题。GHRG-AF分析了巴西成人健康纵向研究（ELSA-Brasil）的数据，该研究是巴西15105名中年人的长期队列，重点关注心血管疾病和糖尿病。此外，GHRG-AF 还使用了巴西中风死亡率和发病率研究 (EMMA) 的数据，以了解房颤对这批 1863 名中风幸存者的影响，这些幸存者都住进了社区医院。GHRG-AF 还调查了医疗实践和心房颤动患者的生活路径，采访了圣保罗不同医疗单位的医疗专业人员和接受治疗的患者。尽管采取了上述多种方法，但这些数据仅限于生活在大城市中心的人群。巴西约 70% 的领土由人口稀少的城市（10 人/平方公里）组成，这些城市作为一个群体，居住着 1500 万人。在新的一步中，GHRG-AF 合作者的目标是提高巴西亚马逊偏远地区的心血管研究能力，制定以患者为中心的方案，增强该地区社区卫生人员的能力，并加强与该国偏远地区其他研究小组的合作。

Background

Pulmonary vein isolation (PVI) is superior to antiarrhythmics for the management of atrial fibrillation, but repeat ablation is often required for durable rhythm control. Factors influencing first-pass isolation (FPI) and whether FPI predicts durable isolation are not well known.

Objective

The study sought to determine factors associated with FPI and rates of chronic reconnection among those with and without FPI at index PVI in patients undergoing repeat ablation.

Methods

We retrospectively identified 483 patients at our institution who underwent first-time PVI in 2021. Of these, 63 who had repeat ablation between 2021 and 2023 were included in the study. Logistic regression was used for statistical analysis for predictors of FPI during index PVI.

Results

The mean age was 65 years, 67% of patients were male, 90% were White, and 73% had persistent atrial fibrillation. At index PVI, FPI was achieved in 58% of left pulmonary veins (PVs), 48% of right PVs, and 25% of posterior wall isolations. Bilateral FPI was achieved in 35% of patients. At redo PVI, the right superior PV (47%) was most frequently reconnected. Lack of PFI of the right PVs at index PVI was associated with a 14-fold risk of chronic reconnection. Elevated left atrial voltage predicted the absence of FPI of the right PVs but not the left PVs.

Conclusion

Increased left atrial voltage predicts a lack of FPI in the right PVs but not in the left PVs. Lack of FPI of right PVs predicts chronic reconnection.

背景肺静脉隔绝术（PVI）在治疗心房颤动方面优于抗心律失常药物，但通常需要重复消融以获得持久的心律控制。本研究旨在确定与 FPI 相关的因素，以及接受重复消融术的患者中在指数 PVI 时有 FPI 和没有 FPI 的患者的慢性再连接率。其中，63 名在 2021 年至 2023 年间接受过重复消融术的患者被纳入研究。结果平均年龄为 65 岁，67% 的患者为男性，90% 为白人，73% 为持续性心房颤动。在指数 PVI 时，58% 的左肺静脉 (PV)、48% 的右肺静脉和 25% 的后壁分离实现了 FPI。35%的患者实现了双侧 FPI。在重做 PVI 时，最常重新连接的是右上肺静脉（47%）。指数 PVI 时右侧 PV 缺乏 PFI 与慢性再连接风险增加 14 倍有关。结论左心房电压升高可预测右上腹静脉缺乏 FPI，但不能预测左上腹静脉。右侧 PV 缺乏 FPI 预示着慢性再连接。
