![]() ![]() Catheter ablation for atrial fibrillation is associated with lower incidence of stroke and death: data from Swedish health registries. It uses heat from radio waves to destroy targeted tissue areas. They include: Radiofrequency ablation: This option is more common. There are two methods of creating scar tissue. Radiofrequency ablation vs antiarrhythmic drugs as first-line treatment of paroxysmal atrial fibrillation (RAAFT-2): a randomized trial. Pulmonary vein isolation is a type of catheter ablation, which means it delivers ablation therapy through a long tube inserted into a vein. Figure 2 shows better survival rates in group 1 patients who maintained NSR after ablation compared to group 1 patients who remained in AF after ablation and group 2 patients however, the benefit on survival rate did not appear until after 2 years of follow-up. Recurrent atrial flutter or tachycar-dia post-ablation may be better managed with a repeat procedure as such arrhythmias can be difficult to rate control, frequently recur after cardioversion, and are often due to gaps in areas of prior ablation and have a relatively high success rate with repeat ablation. ![]() Long‐term outcomes of catheter ablation of atrial fibrillation: a systematic review and meta‐analysis. Depending on the type of arrhythmia being treated, catheter ablation can have a success rate of more than 90 percent, but some people may need to have the. Annual mortality rates were 4 and 9.8 for groups 1 and 2, respectively ( P <.0001). ![]() The seamless integration of three-dimensional rotational angiography images into electroanatomical mapping systems to guide catheter ablation of atrial fibrillation. The success rate is pretty high for an ablation for flutter. doi:10.3978/j.issn.2072-1439.2014.12.46įujita S, Fujii E, Kagawa Y, Inoue K, Yamada T, Ito M. Research shows that ablation stops atrial fibrillation from happening for at least 1 year in about 60 to 90 out of 100 people. In patients with typical atrial flutter, the long-term success rate of cavo-tricuspid isthmus (CTI) ablation is more than 90. Is pulmonary vein isolation still the cornerstone in atrial fibrillation ablation? J Thorac Dis. 2014 AHA/ACC/HRS guideline for the management of patients with atrial fibrillation: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines and the Heart Rhythm Society. ![]()
