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]
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.
A major reason for recurrence of atrial fibrillation after ablation has been the belief of electrical pulmonary vein reconnection, which has not been seen for PFA. [7] In one study, atrial fibrillation recurrence in the thermal ablation group was 39% compared to 11% in the PFA group. [8]
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).
This procedure is performed by cardiac electrophysiologists and has high success rate in the hands of an experienced electrophysiologist. [26] Findings from 1994 indicate success rates of as high as 95% in people treated with radiofrequency catheter ablation for WPW. [27]
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]
For TIC due to atrial fibrillation, rate control, rhythm control, and RF catheter ablation can be effective to control the tachyarrhythmia and improve left ventricular systolic function. [ 5 ] [ 9 ] For TIC due to atrial flutter, rate control is often difficult to achieve, and RF catheter ablation has a relatively high success rate with a low ...
