Blood clots resulting in stroke (1 in 200 risk).Buildup of fluid in the sac around the heart needing a drain to remove the fluid (1 in 200 risk).Damage to blood vessels needing further procedure or blood transfusion (1-2 in 100 risk).You will subsequently be asked to sign a consent form. Your physician will have a detailed discussion with you about the procedure in order to allow you to make an informed decision. The risk of death from an atrial flutter ablation procedure is very small (less than 3 in 1000). For the common type of atrial flutter (typical atrial flutter), the risk of serious complications is 1 in 100 (1%) or less (specific numbers are included below). While complications associated with catheter ablation for atrial flutter are rarely seen, they can be significant. In the remaining 5%, an additional procedure maybe necessary to eliminate the arrhythmia. What are the success rates and potential risks?įor the common type of atrial flutter (typical atrial flutter), the success rates associated with ablation of atrial flutter are 95%.
The end result of the modification is that the abnormal circuit and consequently atrial flutter is eliminated. The basic principle of the procedure is to identify the region of the heart where the abnormal electrical circuit that causes atrial flutter is located and to modify the heart tissue in that region by delivering heat (radiofrequency energy). What does a catheter ablation procedure involve?Ĭatheter ablation is a minimally invasive procedure.
