Abstract Background Catheter ablation improves clinical outcomes in symptomatic atrial fibrillation (AF) patients with heart failure (HF) with reduced ejection fraction (HFrEF). However, the role of catheter ablation in HF patients with a preserved ejection fraction (HFpEF) is less clear. Purpose To determine the efficacy of catheter ablation of AF in patients with HFpEF relative to those with HFrEF. Methods We performed an extensive literature search and systematic review of studies that compared AF recurrence at one year after catheter ablation of AF in patients with HFpEF versus those with HFrEF. Risk ratio (RR) 95% confidence intervals were measured using the Mantel-Haenszel method for dichotomous variables, where a RR<1.0 favors the HFpEF group. Results Four studies with a total of 563 patients were included, of which 312 had HFpEF and 251 had HFrEF. All patients included were undergoing first time catheter ablation of AF. Patients with HFpEF experienced similar recurrence of AF one year after ablation on or off antiarrhythmic drugs compared to those with HFrEF (RR 0.87; 95% CI 0.69–1.10, p=0.24), as shown in Figure 1. Recurrence of AF was assessed with electrocardiography, Holter monitoring, and/or event monitoring at scheduled follow-up visits and final follow-up. Conclusion Based on the results of this meta-analysis, catheter ablation of AF in patients with HFpEF appears as efficacious in maintaining sinus rhythm as in those with HFrEF.

Procedural Complications

Introduction: Women undergoing atrial fibrillation catheter ablation (AFCA) have higher rates of vascular complications and major bleeding. However, studies have been underpowered to detect differences in rare complications such as stroke/transient ischemic attack (TIA) and procedural mortality. Methods: We performed a systematic review of databases (PubMed, World of Science, Embase) to identify studies published since 2010 reporting AFCA complications by gender. Six complications of interest were: 1) vascular/groin complications; 2) pericardial effusion/tamponade; 3) stroke/TIA; 4) permanent phrenic nerve injury; 5) major bleeding & 6) procedural mortality. For meta-analysis, random effects models were used when heterogeneity between studies was ≥ 50% (vascular complications, major bleeding) and fixed effects models for other endpoints. Results: Of 5716 citations, 19 studies met inclusion criteria, comprising 244,353 patients undergoing AFCA, of whom 33% were women. Women were older (65.3 ± 11.2 vs. 60.4 ± 13.2 years), more likely hypertensive (60.6 vs. 55.5%) and diabetic (18.3 vs. 16.5%) and had higher CHA 2 DS 2 -VASc scores (3.0 ± 1.8 vs. 1.4 ± 1.4) (p<0.0001 for all comparisons). The rates of all 6 complications were significantly higher in women (Table). However, despite statistically significant differences, the overall incidences of major complications were very low in both genders: stroke/TIA (women 0.51 vs. men 0.39%) and procedural mortality (women 0.25 vs. men 0.18%). Conclusion: Women experience significantly higher rates of AFCA complications. However, the incidence of major procedural complications is very low in both genders. The higher rate of complications in women may be partially attributable to older age and a higher prevalence of comorbidities at the time of ablation. More detailed studies are needed to better define the mechanisms of increased risk in women and to identify strategies for closing the gender gap.
