A catâs gums may appear swollen and/or bleed when brushed or when the cat eats. Slight browning around the teeth and gums is also common during this phase. Gums with later-stage gingivitis exhibit symptoms that include receding gum tissue and deep pockets between the catâs teeth.
Radiofrequency Ablation for Arthritis Pain. Radiofrequency ablation (or RFA) is a procedure used to reduce pain. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area.
Catheter ablation is a procedure that uses radiofrequency energy (similar to microwave heat) to destroy a small area of heart tissue that is causing rapid and irregular heartbeats. Destroying this tissue helps restore your heartâs regular rhythm. The procedure is also called radiofrequency ablation. Catheter ablation is a low-risk procedure that is successful in about 90 percent of the people who have it. 2  This procedure takes place in a special hospital room called an electrophysiology (EP) lab or a cardiac catheterization (cath) lab. 3  It takes 2 to 4 hours.
