- Background: Catheter ablation (CA) has become a conventional treatment for atrial fibrillation (AF), but remains with high recurrence rate. The aim of this meta-analysis was to determine left atrial (LA) structure and function indices that predict recurrence of AF.Methods: We systematically searched PubMed-Medline, EMBASE, Scopus, Google Scholar and the Cochrane Central Registry, up to September 2017 in order to select clinical trials and observational studies which reported echocardiographic predictors of AF recurrence after CA. Eighty-five articles with a total of 16 126 patients were finally included.Results: The pooled analysis showed that after a follow-up period of 21 +/- 12 months, patients with AF recurrence had larger LA diameter with weighted mean difference (WMD: 2 center dot 99 ([95% CI 2 center dot 50-3 center dot 47], P<0 center dot 001), larger LA volume index (LAVI) maximal and LAVI minimal (P<0 center dot 0001 for both), larger LA area (P<0 center dot 0001), lower LA strain (P<0 center dot 0001) and lower LA total emptying fraction (LA EF) (P<0 center dot 0001) compared with those without AF recurrence. The most powerful LA predictors (in accuracy order) of AF recurrence were as follows: LA strain <19% (OR: 3 center dot 1[95% CI, -1.3-10 center dot 4], P<0 center dot 0001), followed by LA diameter >= 50 mm (OR: 2 center dot 75, [95% CI 1 center dot 66-4 center dot 56,] P<0 center dot 0001), and LAVmax >150 ml (OR: 2 center dot 25, [95% CI, 1.1-5 center dot 6], P = 0 center dot 0002).Conclusions: Based on this meta-analysis results, a dilated left atrium with diameter more than 50 mm and volume above 150 ml or myocardial strain below 19% reflect an unstable LA that is unlikely to hold sinus rhythm after catheter ablation for atrial fibrillation.
