Using real-world data, researchers found that 81.6% of patients were free from AFib one year after RF-based ablation - a higher percentage than attained in clinical trials.
New data indicates that more than 80% of patients who received radiofrequency-based ablation were free from any form of atrial arrhythmia at a one-year followup.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Catheter ablation of most arrhythmias has a high success rate. Success rates for WPW syndrome have been as high as 95% [2] For Supraventricular tachycardia (SVT), single procedure success is 91% to 96% (95% Confidence Interval) and multiple procedure success is 92% to 97% (95% Confidence Interval). [3]
Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [ 11 ] [ 12 ] It often begins as short periods of abnormal beating , which become longer or continuous over time. [ 4 ]
Ablation has been shown to be highly effective: around 90% in the case of AVNRT. Similar high rates of success are achieved with AVRT and typical atrial flutter. [25] Cryoablation is a newer treatment involving the AV node directly. SVT involving the AV node is often a contraindication to using radiofrequency ablation due to the small (1% ...
[6] [7] It is performed without surgery, by using radiofrequency catheter ablation with one-day hospital. [citation needed] The results up to 100 months follow-up are showing better outcome than clinical measures or pacemaker implantation with changing the tilt-test on to normal and by absence of syncope in more than 90% of patients without ...
Findings from 1994 indicate success rates of as high as 95% in people treated with radiofrequency catheter ablation for WPW. [27] If radiofrequency catheter ablation is successfully performed, the condition is generally considered cured. Recurrence rates are typically less than 5% after a successful ablation. [26]
