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).
Uterine fibroids affect up to 80% of women by the age of 50 and can cause debilitating symptoms, including heavy menstrual bleeding, pelvic pain, and fertility challenges. The Sonata ® Procedure utilizes ultrasound-guided RF ablation to target and treat fibroids from within the uterus, without the need for incisions.
Radio frequencies at non-ablation energy levels are commonly used as a part of aesthetic treatments that can tighten skin, reduce fat by lipolysis and also apoptosis, [4] or promote healing. [ 5 ] RF diathermy is a medical treatment that uses RF induced heat as a form of physical therapy and in surgical procedures.
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]
It is a different treatment modality to conventional radiofrequency thermocoagulation / pulsed radiofrequency nerve ablation, a surgical procedure which involves continuous electrical stimulation and increasing temperature around the needle, resulting in destruction (ablation) of tissues. [63]
Radiofrequency-based ablation works by applying bursts of energy to tissue in the heart via a catheter. The subsequent formation of scar tissue disrupts the abnormal electrical signaling that ...
Ablation therapy is a catheter based ablation of lesions in the heart (with radiofrequency energy, cryotherapy (destructive freezing), microwave, or ultrasound energy) to cure or control arrhythmias (see radiofrequency ablation). Ablation is usually performed during the same procedure as the electrophysiology study during which arrhythmias are ...
Endometrial ablation is a surgical procedure that is used to remove or destroy the endometrial lining of the uterus. The goal of the procedure is to decrease the amount of blood loss during menstruation (periods). Endometrial ablation is most often employed in people with excessive menstrual bleeding following unsuccessful medical therapy. [1]
