endometrial ablation removal of the endometrium; methods used include radiofrequency, electrical energy, lasers, and hot and cold liquids.
radiofrequency ablation (radiofrequency catheter ablation) destruction of an accessory conduction pathway or other troublesome area of dysrhythmia by means of unmodulated high frequency alternating current delivered by a bipolar or unipolar catheter. The current causes heat with tissue destruction and formation of scar tissue to block the pathway or dysrhythmic area. Transvenous radiofrequency ablation has been successful in treatment of supraventricular tachycardia and is an attractive option to surgery. Called also catheter ablation.

radiofrequency ablation(rād″ē-ō-frē′kwĕn-sē) [ radio + frequency]
Ablation in which an electrode delivers a low-voltage, high-frequency current to cauterize and destroy abnormal tissues. Destruction of electrical conduction pathways in the heart with an intracardiac catheter that removes the abnormal conducting tissues has been used to treat Wolff-Parkinson-White syndrome, atrioventricular re-entrant tachycardia, and other cardiac arrhythmias.
