The main reason for tachycardia recurrence is accessory pathway (Ap)-mediated tachycardia, and the use of the RFCA strategy may be related to recurrence. This study compared the efficacy and safety of two different RFCA strategies for Ap-mediated tachycardia. We compared patients (group M) who underwent RFCA at multiple sites to patients (group S) who underwent RFCA at a single site during the index procedure for Ap-mediated tachycardia. The efficacy and safety were assessed in the two groups. Follow-up was conducted, and the main complications and the incidence of recurrence after RFCA procedures were recorded. Eight hundred eighty-two patients with 898 Aps were enrolled in group S, and 830 patients with 843 Aps were enrolled in group M. The cumulative number of recurrences (rates) in group M and group S at the 1st, 3rd, 6th, 12th, and 24th months after ablation were 4 (0.5%) and 17 (1.9%), p\u2009&lt;\u20090.05; 5 (0.6%) and 27 (3.0%), p\u2009&lt;\u20090.05; 6 (0.7%) and 34 (3.8%), p\u2009&lt;\u20090.05; 6 (0.7%) and 43 (4.8%), p\u2009&lt;\u20090.05; and 7 (0.8%) and 45 (5.0%), p\u2009&lt;\u20090.05, respectively. Complications of chest pain, overactive vasovagal reaction, steam pop, and angina pectoris were rare in both groups. One patient in group M suffered from myocardial infarction before extensive ablation. No valve damage, cardiac tamponade, or other serious adverse events occurred in either group. The extensive ablation strategy reduced the recurrence rate and the need for subsequent ablation of the Ap without increasing the risk of complications.<\/jats:p>","DOI":"10.1038\/s41598-021-92935-0","type":"journal-article","created":{"date-parts":[[2021,6,28]],"date-time":"2021-06-28T10:02:47Z","timestamp":1624874567000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Efficacy and safety of the application of extensive ablation in patients with atrioventricular re-entrant tachycardia (a retrospective study)"],"prefix":"10.1038","volume":"11","author":[{"given":"Guangze","family":"Xu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhikui","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiyan","family":"Lin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,6,28]]},"reference":[{"key":"92935_CR1","first-page":"1","volume":"17","author":"LY Ma","year":"2020","unstructured":"Ma, L.
