Is ablation to atrial fibrillation termination of persistent atrial fibrillation the end point?: A systematic review and meta-analysis

Fanghui LiRui Zeng


The ideal ablation strategy and end point for persistent atrial fibrillation (AF) have not been well founded. Defining periprocedural AF termination as the end point of catheter ablation is still controversial. This meta-analysis aimed to analyze the differences between periprocedural AF termination and non-termination in the long-term AF recurrence rate and postoperative complications. Randomized controlled trials (RCTs) were identified by a systematic search of electronic databases including PubMed, EMBASE, and Cochrane library from January 2008 to August 2019. The primary outcome was freedom from AF or any atrial arrhythmia without antiarrhythmic drugs at the long-term (≥12 months) follow-up. The secondary outcome was overall postoperative complication rates. The risk ratio (RR) with 95% confidence interval (CI) was pooled for these outcomes. A forest plot, fixed-effects model or random-effect model, Q test, I statistic, and Egger funnel plot were used in the statistical analysis. Fourteen RCTs were included in this meta-analysis. Overall, no significant difference was found in freedom from AF at the long-term follow-up between patients in whom AF termination was achieved and not achieved (RR = 0.93, 95% CI = 0.78-1.09, P = ...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.


Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.
