Objective

Catheter ablation is effective in the treatment of ventricular tachycardia (VT). However, long-term outcomes after VT ablation in non-ischemic cardiomyopathy are sparsely described. We aimed to compare the outcomes of VT ablation between patients with ischemic cardiomyopathy (ICMP) and non-ischemic cardiomyopathy (NICMP).

Methods

Acute procedural and long-term outcomes of 212 consecutive patients (ICMP, 135; NICMP, 77) who were ablated for sustained VT and followed for a median of 36 months were gathered and analyzed.

Results

Compared with patients with NICMP, patients with ICM were older, more likely to be men, had lower LVEF, more comorbidities, and had a higher number of inducible VTs. Complete procedure success was higher in patients from the NICMP group (88.3 % in NICMP compared to 79.3 % in ICMP). VT recurrence occurred in 54.8 % of ICMP compared to 38.9 % of NICMP (P value = 0.026). The overall mortality rate was 22 % in the ICMP group, compared to 7 % in the NICMP group (P value = 0.007). Additionally, cardiac mortality occurred significantly more in the ICMP group than in the NICMP group (19 % vs. 6 %) (P value = 0.011).

Conclusion

VT ablation in patients with NICMP was found to be an effective and safe approach, achieving acute procedural success in a noticeable number of patients using the currently available catheter mapping and ablation techniques with acceptable low procedural complications. Overall, procedural failures were significantly more frequent in ICMP patients than in NICMP and were consistent with unhealthier long-term outcomes.

目的：导管消融是治疗室性心动过速的有效方法。然而，对于非缺血性心肌病室间隔消融术后的长期预后，报道较少。我们的目的是比较缺血性心肌病（ICMP）和非缺血性心肌病（NICMP）患者VT消融的结果。方法：连续212例患者的急性手术和长期预后(ICMP, 135；NICMP, 77)，因持续VT而消融，中位随访36个月的患者被收集和分析。结果：与NICMP患者相比，ICM患者年龄更大，男性更容易，LVEF更低，合并症更多，诱导性室性血栓数量更多。NICMP组患者的手术成功率更高（NICMP组为88.3%，而ICMP组为79.3%）。ICMP组的室速复发率为54.8%，NICMP组为38.9% （P值= 0.026）。ICMP组的总死亡率为22%，而NICMP组为7% （P值= 0.007）。此外，ICMP组的心脏死亡率明显高于NICMP组（19% vs. 6%）（P值= 0.011）。结论：VT消融在NICMP患者中是一种有效且安全的方法，使用目前可用的导管定位和消融技术，在可接受的低手术并发症的情况下，在相当数量的患者中获得了急性手术成功。总的来说，ICMP患者的手术失败明显比NICMP患者更频繁，并且与不健康的长期预后一致。

Introduction

Several electrocardiograph markers are proposed as predictors of life-threatening arrhythmia in Brugada Syndrome, including the aVR sign. However, results of previous studies were inconsistent. Therefore, we aim to determine whether the aVR sign can predict sudden cardiac death in BrS patients.

Methods

We extracted data from PubMed, Cochrane, and EBSCO using MeSH keywords “Brugada syndrome, sudden cardiac death, arrhythmia”. Inclusion criteria include cohorts from the last 10 years of the BrS population with the aVR sign as a predictor. We excluded patients with channelopathies other than Brugada syndrome and low-quality studies. We assessed the quality of studies using the Newcastle-Ottawa Scale. Data will be presented as odds ratios with 95 % confidence intervals. The endpoint is life-threatening arrhythmia resulting in sudden cardiac death.

Results

From 7 cohort studies (1763 patients), R-wave amplitude ≥3 mV in lead aVR has increased risk of sudden cardiac death (OR = 2.15, 95 % CI = 1.56–2.98, I² = 0 %). R/q ratio ≥0.75 in aVR is also associated with increased risk. All studies were considered good quality based on the Newcastle-Ottawa scale. These markers may be integrated with other factors to identify the high-risk patients.

Conclusion

aVR sign can predict sudden cardiac death in Brugada syndrome and this marker may be considered for risk assessment and lead the management strategy for better prevention.

介绍：几种心电图指标被提出作为Brugada综合征危及生命的心律失常的预测指标，包括aVR体征。然而，以往的研究结果并不一致。因此，我们的目的是确定aVR标志是否可以预测BrS患者的心源性猝死。方法：我们使用MeSH关键词“brugada综合征、心源性猝死、心律失常”从PubMed、Cochrane和EBSCO中提取数据。纳入标准包括过去10年BrS人群的队列，aVR标志作为预测因子。我们排除了除Brugada综合征和低质量研究外的其他通道病变患者。我们使用纽卡斯尔-渥太华量表评估研究的质量。数据将以95%置信区间的比值比表示。终点是危及生命的心律失常，导致心源性猝死。结果：在7项队列研究（1763例患者）中，aVR导联r波振幅≥3mv会增加心源性猝死的风险（OR = 2.15, 95% CI = 1.56-2.98, I2 = 0%）。aVR的R/q比值≥0.75也与风险增加相关。根据纽卡斯尔-渥太华量表，所有研究都被认为质量良好。这些标志物可与其他因素结合识别高危患者。结论：aVR标志可预测brugada综合征心源性猝死，可作为brugada综合征的风险评估指标，指导治疗策略，更好地预防。
