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).

In one study, atrial fibrillation recurrence in the thermal ablation group was 39% compared to 11% in the PFA group. [8] PFA can achieve pulmonary vein isolation faster than other ablation methods. [ 1 ] [ 8 ] Compared to radiofrequency ablation, PFA produces lesions of greater uniformity.
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).
The Cox maze procedure, also known as maze procedure, is a type of heart surgery for atrial fibrillation. "Maze" refers to the series of incisions arranged in a maze -like pattern in the atria . Today, various methods of minimally invasive maze procedures, collectively named minimaze procedures , are used.
A 2013 review found the results of the minimally-invasive mini-maze procedure to be intermediate between the standard maze procedure and catheter ablation. [16] Long-term success of the minimaze procedures awaits a consensus. Attaining a consensus is hindered by several problems; perhaps the most important of these is incomplete or inconsistent ...
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 ]
[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 ...
The patient will probably feel fine within 8 to 12 hours after the procedure, but may feel a small pinch at the insertion site. After a short period of general rest, the patient may resume some minor activity such as gentle, short, slow walks after the first 24 hours. If stairs must be climbed, they should be taken one step at a time and very ...
