BACKGROUND: Decision making regarding a patient who has experienced a first clinical episode of atrial fibrillation (AF) is challenging, and the AF recurrences should be a significant consideration. Continuous long-term rhythm monitoring via implantable loop recorders (ILRs) has enabled us to evaluate the AF recurrence profile after the first clinical episode and to investigate clinical parameters associated with the course of the arrhythmia. HYPOTHESIS: Continuous rhythm monitoring via ILRs in AF patients after the first clinical episode is of clinical significance and precisely evaluate the AF recurrence profile...

OBJECTIVES: Circumferential pulmonary vein isolation (CPVI) using irrigated radiofrequency is the most frequently used ablation technique for the treatment of atrial fibrillation worldwide. BACKGROUND: To date, no large randomized multicenter trials have evaluated the efficacy and safety of CPVI using robotic navigation (RN) systems compared with the current gold standard of manual ablation (MN). METHODS: In this prospective, international multicenter noninferiority trial, 258 patients with paroxysmal or persistent atrial fibrillation were randomized for CPVI using either RN (RN group, n = 131) or manual ablation (MN group, n = 127)...

OBJECTIVES: This study sought to compare long-term arrhythmia-free survival between electrical circumferential pulmonary vein isolation (PVI) and PVI with the endpoint of unexcitability along the ablation line. BACKGROUND: PVI is the standard ablation strategy of paroxysmal atrial fibrillation, although arrhythmia recurrence in long-term follow-up (FU) is high. The endpoint of unexcitability along the ablation line results in decreased arrhythmia recurrence compared to electrical PVI in 1-year FU...

Atrial fibrosis is the fundamental histopathologic finding in atrial fibrillation (AF) patients and an important predictor of ablation failure beyond pulmonary vein isolation. There is wide variation in the extent and localization of left atrial fibrosis in patients with paroxysmal and nonparoxysmal AF. Box isolation of fibrotic areas is an effective rhythm control concept in patients with paroxysmal AF despite durable pulmonary vein isolation, and this strategy has recently been implemented successfully in initial AF ablation procedures in addition to pulmonary vein isolation for patients with nonparoxysmal AF...

OBJECTIVES: This study sought to determine the extent of lateral esophageal displacement required during mechanical esophageal deviation (MED) and to eliminate luminal esophageal temperature elevation (LETElev ) during pulmonary vein (PV) isolation. BACKGROUND: MED is a conceptually attractive strategy of minimizing esophageal injury while allowing uninterrupted energy delivery along the posterior left atrium during PV isolation. METHODS: MED was performed using a malleable metal stylet within a plastic tube placed within the esophagus...

OBJECTIVES: The goal of this study was to determine whether a strategy of early re-isolation of pulmonary vein (PV) reconnection in all patients, regardless of symptoms, would reduce the recurrence of atrial fibrillation (AF) and improve quality of life. BACKGROUND: Lasting pulmonary vein isolation (PVI) remains elusive. PV reconnection is strongly linked to the recurrence of arrhythmia. METHODS: A total of 80 patients with paroxysmal AF were randomized 1:1 after contact force-guided PVI to receive either standard care or undergo a repeat electrophysiology study after 2 months regardless of symptoms (repeat study)...

OBJECTIVES: This study aimed to determine incidence of pulmonary vein stenosis (PVS) and evaluate PVS-related symptoms. BACKGROUND: The real-life incidence of PVS after radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) is unknown. METHODS: All patients who underwent RFCA of AF from 2005 to 2016 with routine pre- and post-ablation screening by magnetic resonance imaging or computed tomography were included. Primary ablation strategy was PV antrum isolation alone in all patients...

OBJECTIVES: This study sought to determine the exact period after pulmonary vein antrum isolation (PVI) during which early recurrence of atrial tachyarrhythmia (ERAT) does not predict late arrhythmia recurrence (LR), in order to better define the blanking period. BACKGROUND: Recurrence of atrial fibrillation after PVI is not uncommon. The first 3 months after PVI have been commonly treated as a blanking period, during which ERAT is not thought to predict LR after PVI; however, recent studies have shown that ERAT does predict LR...

OBJECTIVES: The aim of this paper was to clarify the impact of nonpulmonary vein foci (NPVF) on atrial fibrillation (AF) recurrence after pulmonary vein (PV) isolation. BACKGROUND: NPVF are considered contributing factors for the recurrence of AF after PV isolation, but their exact role remains unclear. METHODS: We retrospectively reviewed 216 patients (paroxysmal AF, n = 172; persistent AF, n = 44) who underwent a second electrophysiological study 6 months after the original PV isolation...

PURPOSE: Atrial fibrillation (AF) is a cardiac arrhythmia characterized by a rapid and irregular heart rhythm. AF types, paroxysmal (PX), persistent (PE) and long-lasting persistent (LSP), requires differences in clinical management. Unfortunately, a significant proportion of AF patients are clinical misclassified. Therefore, our study aim that MALDI-Imaging (IMS) is valuable as a diagnostic aid in AF subtypes assessment. EXPERIMENTAL DESIGN: Patients were clinically classified according guidelines of the European Society of Cardiology...

OBJECTIVES: This study sought to investigate the prognostic implications of the clinical subtype of atrial fibrillation (AF): paroxysmal or persistent. BACKGROUND: Underlying structural abnormalities of the left atrium may be responsible for the initial clinical presentation of AF in either paroxysmal or persistent form, yet the prognostic implications of the clinical subtype on presentation are unknown. METHODS: Over a median of 7 years, 1,773 patients (age 64 ± 12 years, 74% males) with nonvalvular AF with index presentations for paroxysmal or persistent AF were followed for the occurrence of all-cause mortality...

Nesfatin-1, a newly discovered adipokine, inhibits inflammatory response. Inflammation is involved in the mechanism of atrial fibrillation (AF). We aim to determine the association between serum nesfatin-1 concentrations and AF. A population of 200 patients with AF and 108 patients without AF were enrolled in this study. These patients were divided into three subgroups of paroxysmal AF, persistent AF, and permanent AF. Serum nesfatin-1 concentrations were lower in AF patients than in controls. Logistic regression analysis showed that serum nesfatin-1 concentrations were inversely associated with AF...

Pacemaker induced tachycardia (PIT) is a rare iatrogenic rhythm disorder which tipically occurs in patients with dual-chamber pacemakers and has different causes, including oversensing of atrial tachyarrhythmia waves. Cor triatriatum sinistrum is a congenital abnormality infrequent in adults, associated with a high risk of atrial tachyarrhythmia. We present the case of a 80-year-old woman incidentally diagnosed with cor triatriatum sinistrum echocardiographycally, implanted with a DDD pacemaker for sinus node disease, who developed atrial tachyarrhythmia (paroxysmal atrial fibrillation and left atrial tachycardia), which triggered a PIT, successfully aborted by automatic mode switch...

Aims: The efficacy of the second-generation cryoballoon (CB) ablation in patients with atrial fibrillation (AF) has been demonstrated previously. Data on the efficacy of CB ablation in elderly patients is missing. The aim of this study was to evaluate the long-term success rate of pulmonary vein isolation (PVI) in patients ≥75 years vs. <75 years using the second-generation 28mm CB. Methods and results: Eighty patients [n = 40 ≥75 years (Group 1); n = 40 <75 years (Group 2)] with paroxysmal [n = 37 (46%) or persistent (n = 43 (54%)] AF were included...
