Radiofrequency ablation (RFA) is a minimally invasive medical procedure that generates heat from high-frequency alternating current and then uses it to eliminate or ablate certain tissues in the body. This procedure is widely used in a variety of medical specialties, including interventional radiology and cardiology, and is especially helpful in treating tumors, cardiac arrhythmias, and chronic pain. The method involves introducing a tiny needle or catheter into the desired location and applying radiofrequency radiation to induce localized heating. This heat causes the destruction of aberrant tissue, diminishing or eliminating its function.
