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).
Targeted radiofrequency ablation (also written t-RFA) is a minimally invasive procedure to treat severe pain and discomfort caused from metastatic tumors in the vertebral body of the spine. This procedure uses radiofrequency energy to target and ablate a specific spinal tumor, causing it shrink and reduce the pressure on the surrounding nerves ...
Lumbar sympathetic neurolysis is performed by using absolute alcohol, but other chemicals such as phenol, or other techniques such as radiofrequency or laser ablation have been studied. To aid in the procedure, fluoroscopy or CT guidance is used. Fluoroscopic guidance is the most frequent, giving better real-time monitoring of the needle.
A cardiac ablation is a treatment for irregular heartbeats. It's described by the Cleveland Clinic as a "minimally invasive procedure that creates scars to stop the electrical impulses that cause ...
Neurotomy may refer to the application of heat (as in radiofrequency nerve lesioning), chemical ablation, or freezing of sensory nerves to cause their temporary degeneration, usually to relieve chronic pain. Neurotomy and neurolysis are forms of nerve block surgery performed in cases, such as for the knee, by an outpatient procedure.

Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
