Adjunctive posterior wall isolation for patients with persistent atrial fibrillation: A systematic review and meta-analysis

Figures

• 

  Figure 1. PRISMA flow diagram of study screening and selection. RCT= randomized controlled trial.

• 

  Figure 2. Meta-analysis of efficacy endpoints in patients with atrial fibrillation undergoing pulmonary vein isolation (PVI) with adjunctive posterior wall isolation (PWI). Forest plots presenting the risk ratio (RR) and 95% confidence interval (CI) for each treatment strategy on freedom from atrial tachyarrhythmia (A), freedom from atrial fibrillation (B), and freedom from atrial tachyarrhythmia after a single ablation procedure (C). CI = confidence interval; MH = Mantel-Haenszel; RR = risk ratio.

  Figure 3. Meta-analysis of efficacy endpoints in patients with atrial fibrillation undergoing PVI with adjunctive PWI. Forest plots presenting RR and 95% CI for each treatment strategy on freedom from atrial tachyarrhythmia in patients with long-standing persistent atrial fibrillation. Abbreviations as in Figure 2.

• 

  Figure 4. Meta-analysis of procedural endpoints in patients with atrial fibrillation undergoing PVI with adjunctive PWI. Forest plots presenting RR and 95% CI for each treatment strategy on total procedure time (A), ablation time (B), and fluoroscopy time (C). IV = inverse variance; other abbreviations as in Figure 2.

• 

  Figure 5. Subgroup analysis of the primary outcome in patients with atrial fibrillation undergoing PVI with adjunctive PWI stratified by PWI technique. Forest plots presenting RR and 95% CI for each subgroup strategy on freedom from atrial tachyarrhythmia recurrence stratified by (1) direct PWI vs (2) box isolation. BOXI = box isolation; other abbreviations as in Figure 2.
