Abstract

Introduction: Although ablation of typical atrial flutter (AFL) can be easily achieved with radiofrequency energy (RF), no studies compare the effectiveness of different ablation catheters. Our study aimed to compare the efficacy of various types of ablation catheters in treating typical AFL.

Methods: We analyzed patients with AFL who underwent RF ablation by a single operator at our institution. Successful ablation was evidenced by a bidirectional conduction block (trans-isthmus conduction time ≥ 130 ms or double potentials ≥ 90 ms). Logistic regression was used to compare success rate and linear regression to compare lesion time.

Results: Out of 222 patients, only six did not meet the success criteria (2.7%). The catheters used were non-irrigated, large-tip, internally irrigated (Chili II Boston Scientific), and externally irrigated (non-force-sensing) catheters (Cool Path, Abbott). An externally irrigated force-sensing catheter (TactiCath, Abbott) was used with > 10 gm of force and (LPLD) setting (30 W- 45 °C- 60 s), and high-power short-duration (HPSD) setting (50 W- 43 °C - 12 s). No complications were encountered. The catheter type had no statistically significant association with ablation success. With the use of externally irrigated catheter with contract force-sensing and HPSD settings, statistically significantly shortening of lesion time was achieved 758.3 s, [CI - 1128.29, - 388.35 s] followed by LPLD by 419.0 s [CI - 808.49, - 29.47 s].

Conclusions: The typical atrial flutter radiofrequency ablation procedure had a high success rate, which was not influenced by the type of ablation catheter. Contact force ablation catheter and HPSD are associated with shorter total lesion time.

不同射频消融导管在典型心房颤动消融中的疗效比较。
引言:尽管使用射频能量(RF)可以很容易地实现典型房扑(AFL)的消融,但没有研究比较不同消融导管的有效性。我们的研究旨在比较不同类型的消融导管治疗典型AFL的疗效。方法:我们分析了在我们机构由单一操作员进行射频消融的AFL患者。双向传导阻滞(经峡部传导时间 ≥ 130毫秒或双电位 ≥ 90ms)。Logistic回归用于比较成功率,线性回归用于比较病变时间。结果:在222名患者中,只有6名不符合成功标准(2.7%)。使用的导管为非灌注、大尖端、内部灌注(Chili II Boston Scientific)和外部灌注(非力敏)导管(Cool Path,Abbott)。使用外部冲洗的力感应导管(TactiCath,Abbott) > 10 gm的力和(LPLD)设置(30 W-45°C-60 s),以及高功率短持续时间(HPSD)设置(50 W-43°C-12 s)。未发现并发症。导管类型与消融成功率无统计学显著相关性。使用具有收缩力传感和HPSD设置的外部灌注导管,在统计学上显著缩短了病变时间758.3 s,[CI-1128.29,-388.35 s],随后LPLD缩短了419.0 s[CI-808.49,-29.47 s],其不受消融导管类型的影响。接触力消融导管和HPSD与较短的总损伤时间相关。

期刊介绍: Aims and Scope Cardiology and Therapy is an international, open access, peer reviewed (single-blind), rapid-publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of cardiovascular therapies and interventions, including devices. Studies relating to diagnosis and diagnostics, pharmacoeconomics, public health, quality of life, as well as patient care, management and education are also encouraged. Areas of focus include, but are not limited to, ischaemic heart disease and acute cardiac care, myocardial, valvular, pericardial and congenital heart disease, vascular and pulmonary disease (including hypertension), arrhythmias, heart failure, non-invasive diagnostic techniques, and invasive and interventional cardiology as well as cardiovascular surgery. The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols and short communications such as commentaries and editorials. Cardiolology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. Rapid Publication The journal’s publication timelines aim for a rapid peer review of 2 weeks. If an article is accepted it will be published 3–4 weeks from acceptance. The rapid timelines are achieved through the combination of a dedicated in-house editorial team, who manage article workflow, and an extensive Editorial and Advisory Board who assist with peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model this allows for the rapid, efficient communication of the latest research and reviews, fostering the advancement of cardiovascular therapies. Personal Service The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning authors will always have an editorial contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE, GPP and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research. Digital Features and Plain Language Summaries Cardiology and Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’. For examples of digital features please visit our showcase page https://springerhealthcare.com/expertise/publishing-digital-features/ Publication Fees Upon acceptance of your article for publication, authors will be required to pay the mandatory Rapid Service Fee of £3650/€4500/$5100. The journal will consider fee discounts for developing countries and this is decided on a case by case basis. Open Access All articles published by Cardiology and Therapy are published open access. Peer Review Process Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria. At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials and Letters which are generally reviewed by one member of the Editorial Board. Where reviewer recommendations are conflicted, the editorial board will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed). Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case by case basis and should be sent to the journal editor. Preprints We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals. Authors should disclose details of preprint posting during the submission process or at any other point during consideration in one of our journals. Once the preprint is published, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.
