Introduction

The impact of protein-energy malnutrition (PEM) on patients hospitalized for conventional pacemaker implantation remains poorly understood.

Methods

We utilized the 2020 U.S. National Inpatient Sample (NIS) database to evaluate the impact of PEM on the in-hospital outcomes of patients who underwent conventional pacemaker implantation. Patients aged 18 and older were identified by ICD-10 CM and PCS codes. Multivariable survey logistic and linear regression analyses were employed to examine in-hospital outcomes, including in-patient mortality, system-based outcomes, and post-procedural complications.

Results

A total of 108 020 patients were identified with 4315 (3.99%) diagnosed with PEM. The mean age of the cohort was 76 years, and 47.5% were female. The overall mortality rate among patients undergoing pacemaker implantation was 1.07%. After adjusting for various patient and hospital confounding factors, PEM was significantly associated with an increased risk of in-hospital mortality (aOR 3.30, 95% CI 2.33–4.88, p < 0.001), prolonged hospital stay (β_LOS 7.89, 95% CI 6.88–8.90, p < 0.001), and an increased risk of various complications such as sepsis (aOR 2.56, 95% CI 1.56–4.19, p < 0.001) along with other post-procedural complications including bleeding/anemia (aOR 2.48, 95% CI 1.98–3.10, p < 0.001), pneumothorax (aOR 2.47, 95% CI 1.71–3.58, p < 0.001), and pericardial complications (aOR 1.65, 95% CI 1.14–2.40, p = 0.008).

Conclusion

PEM was associated with an increased risk of in-hospital mortality, extended hospital stays, and various post-procedural complications in patients undergoing conventional pacemaker implantation. Hence, prompt identification and effective management of PEM are essential for improving post-procedural outcomes in these patients.

导读：蛋白质-能量营养不良（PEM）对传统起搏器植入住院患者的影响仍然知之甚少。方法：我们利用2020年美国国家住院患者样本（NIS）数据库评估PEM对接受常规起搏器植入的患者住院结果的影响。年龄在18岁及以上的患者通过ICD-10 CM和PCS代码进行识别。采用多变量调查逻辑分析和线性回归分析来检查住院结果，包括住院死亡率、基于系统的结果和手术后并发症。结果：共检出108020例患者，其中4315例（3.99%）确诊为PEM。该队列的平均年龄为76岁，女性占47.5%。接受心脏起搏器植入的患者总死亡率为1.07%。在调整各种患者和医院混杂因素后，PEM与院内死亡风险增加显著相关（aOR 3.30, 95% CI 2.33-4.88, plos 7.89, 95% CI 6.88-8.90, p p p p p = 0.008）。结论：PEM与常规起搏器植入患者住院死亡率增加、住院时间延长和各种术后并发症相关。因此，及时识别和有效管理PEM对于改善这些患者的术后预后至关重要。

Background

Cardiac amyloidosis (CA) is frequently complicated by atrial fibrillation (AF), yet outcomes after left atrial appendage occlusion (LAAO) in this population remain poorly defined.

Methods

We conducted a retrospective TriNetX study of adults with AF undergoing LAAO, comparing patients with and without CA after 1:1 propensity matching. Outcomes were assessed using Kaplan–Meier analyses and Cox regression.

Results

Among 532 matched pairs, mortality and major adverse cardiovascular events were similar between groups, whereas major bleeding was higher in CA (HR 1.90).

Conclusions

LAAO yields comparable ischemic outcomes in CA, though bleeding risk is increased.

背景：心脏淀粉样变性（CA）经常并发心房颤动（AF），然而在这一人群中左心耳闭塞（LAAO）后的结果仍然不明确。方法：我们对接受LAAO的成人房颤患者进行了回顾性TriNetX研究，在1:1倾向匹配后比较有和没有CA的患者。结果采用Kaplan-Meier分析和Cox回归进行评估。结果：在532对配对患者中，两组之间的死亡率和主要不良心血管事件相似，而CA的主要出血较高（HR 1.90）。结论：LAAO在CA中产生类似的缺血结果，尽管出血风险增加。

Background

Rare pathogenic variations of desmosomal genes, particularly in plakophilin-2 (PKP2) and desmoglein-2 (DSG2), have been implicated in arrhythmogenic cardiomyopathy (ACM); however, their potential polygenic contribution remains unclear.

Methods

We performed a genome-wide association study of 104 Japanese patients with ACM and 46 527 controls, adjusting for case–control imbalance.

Results

The strongest association was observed upstream of DSG2 (rs182626537, p = 2.3 × 10⁻⁴²), but the signal was abolished after excluding carriers of pathogenic DSG2 variants, suggesting a synthetic association driven by linkage disequilibrium.

Conclusions

These findings highlight a population-specific genetic architecture of ACM, with DSG2 predominating in the Japanese population.

背景：少见的桥粒体基因的致病变异，特别是在plakophilin-2 （PKP2）和desmoglein-2 （DSG2）中，与心律失常性心肌病（ACM）有关；然而，它们潜在的多基因贡献尚不清楚。方法：我们对104名日本ACM患者和46 527名对照进行了全基因组关联研究，调整了病例-对照不平衡。结果：在DSG2上游观察到最强的关联（rs182626537, p = 2.3 × 10-42），但在排除致病DSG2变异的携带者后，该信号被消除，提示由连锁不平衡驱动的合成关联。结论：这些发现突出了ACM的群体特异性遗传结构，DSG2在日本人群中占主导地位。

Background

Catheter ablation is useful to treat patients with scar-related heart disease and ventricular tachycardia (VT). QDOT Micro catheter is a next generation catheter. Its optimized temperature control and micro-electrode technology are designed to provide more efficient and consistent lesion creation with an accurate myocardial substrate analysis. This study aims to compare the myocardial electro-anatomic maps obtained using QDOT and Pentaray (PR) catheters.

Method

This study enrolled patients with symptomatic VT and indication to perform CA following the latest guidelines. Myocardial electro-anatomic maps were obtained using QDOT and Pentaray (PR) catheters. The primary objective was to assess the absence of sustained VTs or ICD interventions 12 months after the procedure.

Results

Twelve patients were enrolled. The percentage of myocardial scar was higher using QDOTB map (15.5%) compared to PR (13.5%) and QDOTM-map (9%) (< 0.001). The percentage of myocardial borderzone was higher using QDOTB map (7.5%) compared to PR (6%) and QDOTM-map (3%) (p < 0.001). The average EGM amplitude acquired in the myocardial scar was higher in the QDOTM-map (0.24 mV) compared to PR (0.10 mV) and QDOTB-map (0.10 mV) (p < 0.001). The average EGM amplitude acquired in the myocardial borderzone was higher in the QDOTM-map (1.07 mV) compared to PR (0.80 mV) and QDOTB-map (0.72 mV) (p < 0.001). No sustained VT was documented at 12 month FU. No adverse events were documented.

Conclusion

Microelectrode mapping allows detection of higher voltage electrograms compared to standard bipolar mapping and PR mapping. In our small population, the HPSD protocol was used inside the low voltage areas without acute procedural complications.

背景：导管消融术是治疗瘢痕相关性心脏病和室性心动过速（VT）的有效方法。QDOT微导管是新一代导管。其优化的温度控制和微电极技术旨在通过准确的心肌底物分析提供更有效和一致的病变创建。本研究旨在比较QDOT和Pentaray （PR）导管获得的心肌电解剖图。方法：本研究纳入有症状性室性心动过速和指征的患者，按照最新指南进行CA。心肌电解剖图采用QDOT和Pentaray （PR）导管。主要目的是评估术后12个月是否存在持续的心室颤动或ICD干预。结果：12例患者入组。与PR（13.5%）和QDOTM-map（9%）相比，QDOTB图的心肌瘢痕比例（15.5%）更高（p pp）。结论：与标准双极测图和PR测图相比，微电极测图可以检测到更高的电压电图。在我们的小人群中，HPSD方案在低电压区域内使用，没有急性手术并发症。

Background

Catheter-based pulmonary vein isolation (PVI) is an established treatment for atrial fibrillation (AF). While cryoballoon ablation (CBA) is a well-validated single-shot thermal technology, pulsed field ablation (PFA) has emerged as a predominantly non-thermal modality that employs high-voltage electric fields to achieve selective myocardial ablation, potentially minimizing collateral damage. However, comparative evidence between PFA and CBA remains limited.

Objectives

To systematically review and compare the efficacy, safety, and procedural efficiency of PFA versus CBA for PVI.

Methods and Results

A structured systematic database search was conducted up to August 2025, following PRISMA guidelines. Eighteen studies (n = 5638; 2396 PFA and 3242 CBA) were included including two randomized controlled trials. PFA significantly shortened procedure time (mean difference −13.7 min; 95% CI –16.7 to −10.8; p < 0.001), while fluoroscopy time and radiation dose were similar. Both modalities achieved high acute PVI success (95%–100%). At 12-month follow-up, PFA showed lower arrhythmia recurrence (OR 0.73; 95% CI 0.59–0.90; p = 0.003) with no difference in redo ablation. Overall complications were fewer with PFA (OR 0.53; 95% CI 0.32–0.87; p < 0.001), largely due to reduced phrenic nerve injury, though cardiac tamponade occurred slightly more often in the PFA group. Subgroup analyzes yielded consistent results in paroxysmal AF and when 3D mapping was used.

Conclusion

PFA offers superior procedural efficiency and safety compared with CBA, achieving shorter procedures, fewer complications, and lower arrhythmia recurrence at mid-term follow-up. Larger multicentre randomized trials with standardized protocols and long-term follow-up are needed to confirm these findings and evaluate evolving PFA technologies.

背景：基于导管的肺静脉隔离（PVI）是房颤（AF）的既定治疗方法。低温球丸消融（CBA）是一种经过验证的单次热技术，而脉冲场消融（PFA）已经成为一种主要的非热方式，它利用高压电场来实现选择性心肌消融，潜在地将附带损伤降到最低。然而，PFA和CBA之间的比较证据仍然有限。目的：系统回顾和比较PFA与CBA治疗PVI的疗效、安全性和程序效率。方法和结果：按照PRISMA指南，到2025年8月进行了结构化的系统数据库检索。纳入18项研究（n = 5638； 2396 PFA和3242 CBA），包括2项随机对照试验。PFA显著缩短了手术时间（平均差-13.7分钟；95% CI -16.7至-10.8;p = 0.003），而再次消融无差异。结论：与CBA相比，PFA具有更高的手术效率和安全性，手术时间更短，并发症更少，中期随访心律失常复发率更低。需要采用标准化方案和长期随访的大型多中心随机试验来证实这些发现并评估不断发展的PFA技术。

Three atrioventricular reciprocating tachycardias (AVRTs) using 3 accessory pathways (APs) occurred with the His bundle eliminated by the previous ablation. Two AVRTs using 2 right APs rotated reversely, and the other AVRT was one with a retrograde conduction through the left AP and anterograde conduction through the 2 right APs.

3例房室往复式心动过速（AVRTs）通过3个辅助通路（APs）发生，他束因先前消融而消失。两个使用2个右AP的AVRT反向旋转，另一个AVRT通过左AP逆行传导，通过2个右AP顺行传导。

Background

Localizing the site of origin of outflow tract ventricular arrhythmias (OTVA) before ablation remains challenging despite existing ECG algorithms. Anatomical alterations of the aortic root associated with left ventricular outflow tract (LVOT) origin can be visualized through aortoseptal angle measurement. This study investigated the aortoseptal angle for predicting LVOT origin and improving the predictive power of current ECG algorithms.

Methods

Patients undergoing successful OTVA ablation at a national cardiovascular referral hospital were enrolled. Transthoracic echocardiography measured the aortoseptal angle before ablation. Patients with structural abnormalities, multifocal arrhythmias, reduced ejection fraction, unsuccessful ablation, or non-inducible VAs were excluded. Multivariable logistic regression was used to develop a diagnostic model.

Results

Forty-eight patients were included (44.9 ± 12.2 years, 79.8% female). Patients with LVOT origin (17.1%) had higher hypertension prevalence (71.4% vs. 17.6%; p < 0.001) and smaller aortoseptal angles (128.0 ± 6.2 vs. 136.7 ± 5.8; p < 0.001) than right ventricular outflow tract (RVOT) origin. The aortoseptal angle demonstrated good diagnostic performance (AUC 85.5%), comparable to ECG algorithms (V2 transition ratio 90.3%, V2S/V3R index 81.4%). Multivariable analysis identified three independent predictors: hypertension (OR 10.35; 95% CI: 1.07–99.87; p = 0.043), aortoseptal angle (OR 0.79; 95% CI: 0.65–0.96; p = 0.033), and V2 transition ratio (OR 12.12; 95% CI: 1.03–141.48; p = 0.026). The integrated model substantially improved performance (AUC 0.966, sensitivity 92.31%, specificity 88.24%).

Conclusions

Aortoseptal angle measurement by echocardiography effectively identifies LVOT origin. Integration with hypertension status and V2 transition ratio substantially enhances diagnostic accuracy, supporting the use in pre-ablation assessment.

背景：尽管现有的ECG算法，在消融前定位流出道室性心律失常（OTVA）的起源位置仍然具有挑战性。主动脉根部与左心室流出道（LVOT）起源相关的解剖改变可以通过主动脉间隔角测量可视化。本研究探讨了主动脉间隔角对LVOT起源的预测，提高了当前心电算法的预测能力。方法：选取在某国家级心血管转诊医院成功行OTVA消融术的患者。经胸超声心动图测量消融前主动脉间隔角。排除结构异常、多灶性心律失常、射血分数降低、消融不成功或非诱导性VAs的患者。采用多变量logistic回归建立诊断模型。结果：纳入48例患者（44.9±12.2岁，女性79.8%）。LVOT起源患者（17.1%）高血压患病率（71.4% vs. 17.6%; p p p = 0.043）、主动脉间隔角（OR 0.79; 95% CI: 0.65 ~ 0.96; p = 0.033）和V2转换比（OR 12.12; 95% CI: 1.03 ~ 141.48; p = 0.026）较高。综合模型显著提高了诊断效果（AUC 0.966，灵敏度92.31%，特异度88.24%）。结论：超声心动图测量主动脉间隔角能有效识别左室血栓的起源。结合高血压状态和V2转换比大大提高了诊断准确性，支持在消融前评估中的应用。

Cardiac Resynchronization Therapy: Reconsidering Its Essence as a Treatment for Electrical Dyssynchrony in Heart Failure 心脏再同步化治疗：重新考虑其作为心力衰竭电非同步化治疗的本质。

IF 1.7 Q2 CARDIAC & CARDIOVASCULAR SYSTEMS

Cardiac resynchronization therapy (CRT) essentially targets electrical dyssynchrony, one of the key drivers in heart failure (HF). Its efficacy depends on both the quality (QRS morphology) and quantity (QRS duration) of dyssynchrony, requiring individualized patient selection. While drug therapy for HF has a limited effect on this substrate, early implantation of CRT can prevent irreversible remodeling and facilitate optimization of medical therapy. CRT should be recognized as an essential component within a comprehensive strategy for HF management in patients with appropriate indications.

心脏再同步化治疗（CRT）主要针对电非同步化，这是心力衰竭（HF）的关键驱动因素之一。其疗效取决于非同步运动的质量（QRS形态学）和数量（QRS持续时间），需要个体化患者选择。虽然HF药物治疗对该底物的影响有限，但早期植入CRT可以防止不可逆重构，促进药物治疗的优化。CRT应被认为是有适当适应症患者心衰管理综合策略的重要组成部分。
