“…Activated T lymphocytes were found in left atrial endocardium, supporting the role of local inflammation as a potential trigger of AF . CRP, an acute‐phase protein produced in the liver, is a sensitive biomarker of systemic inflammation in several cardiovascular diseases . Elevated CRP levels are associated with increased risk of cardiovascular events .…”

“…ERAF following ablation has been reported to be related to an acute inflammatory process. A longer procedural time of aggressive radiofrequency ablation could lead to massive tissue damage and profound inflammatory processes . Lellouche et al reported that a majority of patients (91%) with ERAF following AF ablation will suffer LRAF, and the reason may be that ERAF affects the remodeling of atrial anatomy after catheter ablation.…”

Background: Atrial fibrillation (AF) is associated with inflammation. Increased serum C-reactive protein (CRP) levels are important representatives of an inflammatory state of AF. A variety of studies have evaluated whether increased CRP levels have an association with AF recurrence after catheter ablation. However, the results remain inconsistent, therefore, this meta-analysis was conducted to offer suggestions. Hypothesis: Increased baseline CRP have an association with AF recurrence after catheter ablation. Methods: Electronic databases including PubMed, Embase, Medline, ISI Web of Knowledge, and ScienceDirect were searched until December 31, 2012 for any CRP-associated studies. Overall and subgroup analyses were performed. Standardized mean difference (SMD) and 95% confidence interval (CI) were used to evaluate the associations between CRP levels and postablation AF recurrence. Statistical analysis was performed with Review Manager 5.2 and Stata 11.0. Results: Seven available studies were identified, which included 526 patients (179 recurrence vs 347 no recurrence). Overall, increased baseline CRP levels had significant positive association with postablation AF recurrence. The SMD in the CRP levels was 0.65 units (95% CI: 0.30-0.99), and the z-score for overall effect was 3.70 (P = 0.0002). The heterogeneity test showed that there were moderate differences between individual studies (P = 0.006, I 2 = 67%). Metaregression revealed that different sample sizes of studies possibly accounted for the heterogeneity. Positive associations were also found in subgroup analyses based on sample size. When stratifying for ethnicity, similarly significant associations were found in both European (Caucasian) and Asian populations. Conclusions: Investigations demonstrate that baseline CRP levels are greater in patients with postablation AF recurrence. Further studies with larger sample size and delicate design for CRP should be conducted. IntroductionAtrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice, and approximately onethird of all cardiac arrhythmia-related hospitalizations are due to AF.

“…In addition, a previous study reported that the percentage of documented AF events with telemonitoring ECG during the first 3 months was higher in patients with long-term failure [17], which implies that early AF recurrence is a significant predictor of late AF recurrence [16]. Furthermore, very early AF recurrence within 2 days after ablation has been reported in 15 % of patients with paroxysmal AF and 34 % with persistent AF, and very early AF recurrence was associated with late recurrence in persistent AF patients [18]. Thus, even very early recurrence should be considered in the risk stratification of the outcome, which might be hidden when a long duration of the blanking period is used.…”

Differences in the methodologies for evaluating atrial fibrillation (AF) ablation outcomes should be evaluated. In the present study, we compared the AF ablation outcomes among periodic clinic electrocardiography (ECG), 24-h Holter ECG, and telemonitoring ECG to evaluate the differences among these methods. In addition, we evaluated the AF-free survival rate for each method with different durations of the blanking period. A total of 30 AF patients were followed up for 6 months after initial catheter ablation, with clinic ECG on every clinic visit, monthly 24-h Holter ECG, and telemonitoring ECG twice daily and upon symptoms. AF relapse was defined as AF or atrial tachycardia detected with any of the methods. Two patients dropped out of the study, and 28 patients were followed up for 8.8 ± 2.7 months. Patients underwent 3.6 ± 0.8 clinic ECG, 5.1 ± 0.8 Holter ECG, and 273 ± 68 telemonitoring ECG examinations. During the first, second, third, fourth, fifth, and sixth months of follow-up, Holter ECG detected relapses in 11.1, 8.3, 11.5, 15.4, 4.2, and 4.8 % of patients and telemonitoring ECG detected relapses in 32.1, 25.0, 25.0, 17.9, 28.6, and 17.9 % of patients, respectively. When no duration was set for the blanking period, the AF-free survival rate was significantly lower with telemonitoring ECG (46.4 %) than with Holter ECG (78.6 %, P = 0.013) or clinic ECG (85.7 %, P = 0.002). In addition, when the duration of the blanking period was set to 3 months, the AF-free survival rate was significantly lower with telemonitoring ECG than with clinic ECG (92.9 vs. 71.4 %, P = 0.041). The AF ablation outcomes with twice-daily telemonitoring ECG might differ from those with clinic ECG when the duration of the blanking period is 0-3 months. A follow-up based solely on clinic ECG might underestimate AF recurrence.

“…Each patient underwent an electrophysiological study and catheter ablation in the fasting, nonsedated state after written informed consent was obtained. The details have been described previously 10–13 . In brief, after completing the left atrium geometry, continuous circumferential lesions were created encircling the right and left pulmonary veins (PVs) ostia guided by the NavX system using either a conventional 4 mm tip or irrigated‐tip catheter.…”

Characteristics and Significance of Very Early Recurrence of Atrial Fibrillation After Catheter Ablation

Abstract: Very early recurrence occurred in patients with paroxysmal AF is not associated with long-term recurrence. Nonparoxysmal AF is an independent predictor of late recurrence of AF in patients with very early recurrence.
