Fourteen patients (67%) were treated for persistent AF and 7\u00a0patients (33%) for atypical atrial flutter. Eighteen patients (86%) had undergone at least one prior ablation procedure. Acute success, defined as sinus rhythm without the ability to provoke the clinical arrhythmia, was achieved in 17\u00a0patients (81%). At 12\u00a0months, 4\u00a0patients treated for persistent AF (29%) and 4\u00a0patients treated for atypical flutter (57%) remained in sinus rhythm. Complications included hemiparesis, for which intra-arterial thrombolysis was given with subsequent good clinical outcome (<jats:italic>n<\/jats:italic>\u202f=\u20091), and complete atrioventricular block, for which a\u00a0permanent pacemaker was implanted (<jats:italic>n<\/jats:italic>\u202f=\u20092).

Despite a\u00a0high acute success rate, the recurrence rate of persistent AF was relatively high. This may be due to the selection of the patients with therapy-resistant arrhythmias and limited experience in the optimal use of this mapping system that is still under development.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s12471-021-01636-w","type":"journal-article","created":{"date-parts":[[2021,10,26]],"date-time":"2021-10-26T13:05:40Z","timestamp":1635253540000},"page":"273-281","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Initial experience with AcQMap catheter for treatment of persistent atrial fibrillation and atypical atrial flutter"],"prefix":"10.1007","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8745-6462","authenticated-orcid":false,"given":"M.","family":"Liebregts","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
