Introduction

Atrial fibrillation (AF) is a prevalent and potentially serious cardiac rhythm disorder. Cryoballoon ablation using the Arctic Front catheter offers a modern treatment approach. This subanalysis evaluates the safety, efficacy, and impact on quality of life for patients undergoing t this procedure in Kazakhstan. The Cryo AF Global Registry (NCT02752737) is an ongoing prospective, multi-center observational post-market registry collecting global data on CBA procedures conducted with the Arctic Front™ Family of Cardiac Cryoablation Catheters.

Methods

The study included patients aged 18 and older with paroxysmal, persistent, and long-standing persistent AF. Key safety endpoints included serious adverse events related to the device or procedure. Efficacy was measured by the absence of AF, atrial flutter (AFL), and/or atrial tachycardia (AT) after a 90-day period of discontinuing antiarrhythmic medications.

Results

No injuries to the phrenic nerve or serious complications were reported. Three serious adverse events occurred, but these were not related to the procedure. At 12 months, the Kaplan-Meier analysis showed a 92.9 % rate of freedom from AF or other atrial arrhythmias after the 90-day blanking period. Two repeat ablations (2.9 %) were needed for AF.

Conclusion

This analysis supports the conclusion that cryoballoon ablation is both safe and effective for treating AF in Kazakhstan, resulting in significant improvements in patients' quality of life.

Registration number

NCT02752737.

心房颤动（AF）是一种普遍且潜在严重的心律失常。使用Arctic Front导管的低温球囊消融提供了一种现代治疗方法。该亚分析评估了哈萨克斯坦接受该手术的患者的安全性、有效性和对生活质量的影响。Cryo AF全球注册（NCT02752737）是一项正在进行的前瞻性、多中心观察性上市后注册，收集使用Arctic Front™系列心脏冷冻消融导管进行CBA手术的全球数据。方法：研究纳入18岁及以上阵发性、持续性和长期持续性房颤患者。主要安全终点包括与设备或手术相关的严重不良事件。通过停用抗心律失常药物90天后房颤、心房扑动（AFL）和/或房性心动过速（AT）的消失来衡量疗效。结果：无膈神经损伤及严重并发症。发生了三个严重的不良事件，但这些与手术无关。在12个月时，Kaplan-Meier分析显示，在90天的空白期后，房颤或其他心房心律失常的自由率为92.9%。AF需要两次重复消融（2.9%）。结论：本分析支持冷冻球囊消融在哈萨克斯坦治疗AF安全有效，显著改善患者生活质量的结论。注册号：NCT02752737。

Fluoroscopy-free ablation techniques have gained popularity in recent years. However, coronary sinus (CS) cannulation via the femoral approach remains technically challenging, particularly when using specialized catheters like the BeeAT™. To demonstrate a reproducible technique for fluoroscopy-free CS cannulation using the BeeAT catheter guided by CARTO® electroanatomical mapping and intracardiac echocardiography (ICE). Forty three patients undergoing atrial fibrillation ablation were enrolled. After 3D mapping of the right atrium and CS ostium identification via ICE, a femoral-type BeeAT catheter was inserted. Direct advancement or RA loop techniques were applied based on anatomy. CARTO settings were adjusted to allow impedance-based catheter visualization. Successful CS cannulation without fluoroscopy was achieved in all 43 cases. The direct technique succeeded in 36 cases, and the RA loop method was used in 7. No complications occurred.

Conclusion

Fluoroscopy-free femoral CS cannulation with the BeeAT catheter is safe, feasible, and enhances procedural efficiency while avoiding radiation exposure.

We report a case of atrioventricular (AV) block post successful percutaneous atrial septal defect (ASD) device closure. He had minimal fatigue and presented for his routine follow-up after intervention. His ECG showed 2:1 AV block. The interesting finding was appearance of varying PR interval in the conducted beats evoking possibility of complete heart block (CHB). We review the literature and conclude that changing PR is part of compensation to maintain R-R interval in a typical Wenckebach phenomenon.

我们报告一例房室（AV）阻滞后成功经皮房间隔缺损（ASD）装置关闭。他有轻微的疲劳，并在干预后进行了常规随访。心电图显示2:1房室传导阻滞。有趣的发现是在传导的心跳中出现不同的PR间隔，引起完全心脏传导阻滞（CHB）的可能性。我们回顾了文献，得出结论：在典型的Wenckebach现象中，改变PR是维持R-R区间的补偿的一部分。

Alternating or variable paced QRS morphologies following pacemaker implantation is an important clinical observation. Patients undergoing pacemaker upgrade where contralateral implantation was performed, old generator usually removed. Some centers prefer either leaving the old device in the body or removal after few weeks due to risk of infection. Leaving old pacemaker in the body might lead to dangerous circumstances such as inhibiting new pacing system in a pacemaker dependent patient. This case highlights the complexities and potential complications of managing dual pacemakers.

起搏器植入后QRS形态的变化是重要的临床观察。接受对侧起搏器植入的患者，通常会移除旧的起搏器。由于有感染的风险，一些中心倾向于将旧设备留在体内或在几周后取出。将旧的起搏器留在体内可能会导致危险的情况，例如抑制依赖起搏器的患者的新起搏系统。本病例突出了管理双起搏器的复杂性和潜在并发症。

Background

Basal crux ventricular tachycardia (VT) is traditionally considered an idiopathic arrhythmia. However, its occurrence in patients with structural heart disease, especially ischemic heart disease (IHD), is often under recognised.

Case summary

We report two patients with a history of myocardial infarction who presented with basal crux VT. In both cases, VT was rendered non-inducible, and both patients experienced recovery of their left ventricular ejection fraction (LVEF), indicating a significant burden of arrhythmia-induced cardiomyopathy.

Discussion

It is unclear whether IHD is purely coincidental or contributes to the underlying substrate promoting arrhythmogenesis.

Conclusion

Basal crux VT can occur in patients with IHD and may resemble idiopathic epicardial VT. Ablation in the proximal middle cardiac vein (MCV) may be potentially curative.

背景：基底窦性室性心动过速（VT）传统上被认为是一种特发性心律失常。然而，它在结构性心脏病，特别是缺血性心脏病（IHD）患者中的发生往往未得到充分认识。病例总结：我们报告了两例有心肌梗死史的患者，他们表现为基底窦性室速。在这两例中，室速都是不可诱导的，两例患者的左心室射血分数（LVEF）都恢复了，这表明心律失常引起的心肌病有很大的负担。讨论：目前尚不清楚IHD是纯粹巧合还是促进心律失常发生的潜在底物。结论：基底结节性室性心动过速可发生于IHD患者，与特发性心外膜室性心动过速相似，近端心中静脉（MCV）消融可能有潜在的治疗效果。
