“…Therefore, repeat RFCA treatment could be one of the treatments for these patients. Observation through use of more intensive monitoring tools could objectively evaluate the characteristics of various atrial arrhythmias after AF RFCA, so that the best strategy and best time of intervention could be established for different types of arrhythmias [20,21]. The 32 patients in this study successfully underwent RFCA, but we still found recurrent AFs, among which 5 cases were successfully treated after repeat RFCA treatment.…”

BackgroundThe aim of this study was to evaluate the value of the implantable loop recorder (ILR) in diagnosing atrial fibrillation (AF) and assessing the postoperative efficacy of radiofrequency catheter ablation (RFCA).Material/MethodsA total of 32 patients who successfully underwent RFCA were selected. These patients discontinued antiarrhythmic medication with no AF recurrence for more than 3 months after RFCA, and underwent ILR placement by a conventional method. The clinical manifestations and information on arrhythmias recorded by the ILR were followed up to assess the efficacy of AF RFCA.ResultsThe mean follow-up period was 24.7±12.5 months. Of 32 patients with ILR information, 27 had successful RFCA and 5 had recurrent AF. The follow-up results obtained by traditional methods showed 29 patients with successful RFCA and 3 with recurrent AF (P<0.05). Among the 18 patients with clinical symptoms, 13 had recorded cardiac arrhythmic events (72.2%) and 5 showed sinus rhythm (27.8%). The ILRs recorded 18 patients with arrhythmic events (56.3%), including 12 cases of atrial arrhythmias, among whom 5 recurred at 9, 12, 16, 17, and 32 months after AF RFCA; there were also 2 patients with ventricular tachycardia (VT) and 4 with bradycardia.ConclusionsThe value of ILR in assessing the efficacy of AF RFCA was superior to that of traditional methods. ILR can promptly detect asymptomatic AF, and can monitor electrocardiogram features after RFCA, thus providing objective evidence of efficacy.

“…1 However, new-onset atrial fibrillation (AF) occurring after successful typical AFL ablation is common. [2][3][4][5][6][7] The incidence of postablation new-onset AF is progressive, with 25% occurring over 1 year, 49% at 2 years, and 68% over 3 years. [5][6][7] Prediction of subsequent AF following ablation of typical AFL is clinically important to optimise the management of AFL in terms of surveillance, continuous antiarrhythmics and/or anticoagulation, or even prophylactic pulmonary vein isolation (PVI) during typical AFL ablation.…”

HATCH score in the prediction of new-onset atrial fibrillation after catheter ablation of typical atrial flutter

et al. 2015

“…Atrial fibrillation (AF) occurrence in patients with typical atrial flutter (AFl) who undergo cavotricuspid isthmus (CTI) ablation is common during follow-up despite antiarrhythmic drug (AAD) treatment, and the occurrence of AF may be favored by similar electrophysiologic triggers and substrates [1], [2], [3], [4], [5]. AF is a progressive arrhythmia and the risk of progression is quantified by the HATCH score, which includes factors of underlying heart disease rather than characteristics of the arrhythmia [6].…”

ObjectiveWe determined the effectiveness of the HATCH score in patients with typical atrial flutter (AFl) undergoing cavotricuspid isthmus (CTI) ablation to predict long-term atrial fibrillation (AF).MethodsWe conducted an observational retrospective single-center cohort study including all patients admitted to our hospital for a CTI ablation between 1998 and 2010. The patients were divided into four categories: 1) new-onset AF (no prior AF and AF during follow-up (FU)); 2) old AF (prior AF and no AF during FU); 3) prior and post AF (AF prior and post CTI ablation); and 4) no AF.ResultsFour hundred and eight patients were included. In patients without prior AF, the hazard ratio (HR) for new-onset AF during FU was 0.98 (CI 95%: 0.65–1.50; p = 0.95) and 1.00 (CI 95%: 0.57–1.77; p = 0.98) for HATCH ≥ 2 and HATCH ≥ 3, respectively. In patients with prior AF, the HR for AF was 1.41 (CI 95%: 0.87–2.28; p = 0.17) and 1.79 (CI 95%: 0.96–3.35; p = 0.06), for HATCH ≥ 2 and HATCH ≥ 3, respectively. Left atrial enlargement was positively correlated with the occurrence of AF during FU, especially in the subgroup without prior AF, which had a HR of 2.44 (CI 95%: 1.35–4.40; p = 0.003), a HR of 2.88 (CI 95%: 1.36–6.10; p = 0.006) and a HR of 3.68 (CI 95%: 1.71–7.94; p = 0.001), for slight, moderate and severely dilated left atrial dimension, respectively, compared with a normal value.ConclusionsHATCH score did not predict AF in patients with typical AFl who underwent CTI ablation. Basal left atrium dimension could help predict new-onset AF.
