摘要
背景：短时间射频消融术旨在提高肺静脉隔离（PVI）的效率。我们研究了一种新的稳定性算法（stability +）的性能。方法：在一项前瞻性、单中心研究中，纳入了连续接受首次PVI的患者。患者分为四组：1组，混合型(前路，50 W, 550 AI；后验，90 W 4 s)；第2组，使用STABILITY +的杂交；第三组，使用Visitag 90 W（前后，90 W 4 s）；第4组，90w使用STABILITY +。系统收集临床、手术和随访资料。结果：共纳入268例患者。总共有130例患者进行了混合消融，138例患者进行了90w消融。第1、2和3组的手术时间相当，但第4组的手术时间较短（65分钟、65分钟、70分钟、54分钟）。结论：无论采用何种消融模式，新型的STABILITY +算法都可以用于PVI消融，而不会影响安全性和效率，并且有可能改善使用90 w HPSD消融的第一次隔离。
Performance of a new respiratory compensated stability algorithm during radiofrequency ablation for atrial fibrillation.
Background: Short-duration radiofrequency ablation is designed to enhance efficiency of pulmonary vein isolation (PVI). We investigated the performance of a novel stability algorithm (STABILITY +).
Methods: In a prospective, single-center study, consecutive patients undergoing first-time PVI were included. Patients were categorized into four groups: Group 1, Hybrid (anterior, 50 W, 550 AI; posterior, 90 W 4 s) using Viistag; Group 2, Hybrid using STABILITY + ; Group 3, 90 W (anterior and posterior, 90 W 4 s) using Visitag; Group 4, 90 W using STABILITY + . Clinical, procedural and follow-up data were systematically collected.
Results: A total of 268 patients were included. In total, 130 patients had Hybrid ablation while 138 underwent 90-W ablation. Procedure time was comparable in Groups 1, 2, and 3 however was lower in Group 4 (65 min, 65 min, 70 min, 54 min, p < 0.001). RF-time was longer in Group 1 and 2 vs 3 and 4 (11.6 min, 9.7 min, 4.5 min, 5.2 min, p < 0.001). First-pass isolation rates were comparable between all 4 groups (88%, 91%, 83.9%, 90%, p = 0.480). Freedom from arrhythmia at 6 months was also comparable (9%, 9%, 16.6%, 10.4%, p = 0.341). Complications were comparable and low and restricted to vascular access-related complications (2%, 1%, 0%, 2%, p = 0.388).
Conclusions: Irrespective of the mode of ablation, the novel STABILITY + algorithm can be used in PVI ablations without compromising safety and efficiency and has the potential to improve first-pass isolation using 90-W HPSD ablation.
期刊介绍：
The Journal of Interventional Cardiac Electrophysiology is an international publication devoted to fostering research in and development of interventional techniques and therapies for the management of cardiac arrhythmias. It is designed primarily to present original research studies and scholarly scientific reviews of basic and applied science and clinical research in this field. The Journal will adopt a multidisciplinary approach to link physical, experimental, and clinical sciences as applied to the development of and practice in interventional electrophysiology. The Journal will examine techniques ranging from molecular, chemical and pharmacologic therapies to device and ablation technology. Accordingly, original research in clinical, epidemiologic and basic science arenas will be considered for publication. Applied engineering or physical science studies pertaining to interventional electrophysiology will be encouraged. The Journal is committed to providing comprehensive and detailed treatment of major interventional therapies and innovative techniques in a structured and clinically relevant manner. It is directed at clinical practitioners and investigators in the rapidly growing field of interventional electrophysiology. The editorial staff and board reflect this bias and include noted international experts in this area with a wealth of expertise in basic and clinical investigation. Peer review of all submissions, conflict of interest guidelines and periodic editorial board review of all Journal policies have been established.
