Alcohol septal ablation was first performed in 1994 by Ulrich Sigwart at the Royal Brompton Hospital in the United Kingdom. [2] Since that time, it has gained favor among physicians and patients due to its minimally invasive nature, thereby avoiding general anesthesia, lengthy inpatient recuperation and other complications associated with open-heart surgery (e.g. septal myectomy).
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).

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.
In a select population with symptoms secondary to a high outflow tract gradient, alcohol septal ablation can reduce the symptoms of HCM. In addition, older individuals and those with other medical problems, for whom surgical myectomy would pose increased procedural risk, would likely benefit from the less-invasive septal ablation procedure. [15 ...
During 10 months between April 2020 and September 2021, complications of alcohol-related disease rose by 33% to 56% among middle-aged women compared with pre-pandemic times, said first author Dr ...
Ordinarily, septal myectomies are performed only after attempts at treatment with medication fail. The choice between septal myectomy and alcohol ablation is a complex medical decision. [citation needed] Septal myectomy was established by Andrew G. Morrow in the 1960s. [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).
For instance, repairs of congenital heart defects are currently estimated to have 4–6% mortality rates. [34] [35] A major concern with cardiac surgery is neurological damage. Stroke occurs in 2–3% of all people undergoing cardiac surgery, and the rate is higher in patients with other risk factors for stroke. [36]
