Radiofrequency ablation is a medical procedure that uses heat generated by radio waves to destroy abnormal tissue in the body. This technique is often used to treat conditions like arrhythmias, where the heart beats irregularly, or to remove tumors in organs such as the liver or kidneys. The procedure is minimally invasive, meaning it usually requires only small incisions or can even be done through the skin. During the procedure, a thin needle or catheter is inserted into the targeted area. Once in place, radiofrequency energy is delivered, heating the tissue and causing it to shrink or die. Patients typically experience less pain and a quicker recovery compared to traditional surgery, making radiofrequency ablation a popular choice for many medical conditions.
