Meta-analysis of the effectiveness of catheter treatment of persistent forms of atrial fibrillation
The aim is to reveal the most effective type of catheter ablation of persistent atrial fibrillation with consideration for complications. The data of 24 studies are presented in the article with a total number of 3115 patients. All the catheter procedures were divided according to the technique of ablation. All the complications were divided into two groups: first one included life-threatening complications, second one included complications that are serious but not life-threatening. For this study a special statistical formula was invented. The formula allows to show the most effective catheter ablation technique with the consideration for complications. Conclusion: The most effective and safe type of catheter ablation of atrial fibrillation is wide ablation circumfiration area with additional ablation line
