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.
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]
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).
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
[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]
Arrhythmias can also occur, most-commonly atrial fibrillation (incidence of 20–40%) that is treated with correcting electrolyte balance, and rate and rhythm control. [ 42 ] [ 38 ] However, arrhythmia such as ventricular tachycardia or fibrillation can be a sign of postoperative myocardial ischemia that is treated depending on the cause.
