Ablation, derived from the Latin for 'to remove or destroy,' is a minimally invasive medical procedure. It typically employs radiofrequency energy or cryoablation (freezing) to precisely target and eliminate specific tissues. In cardiology, ablation is used to treat abnormal heart rhythms by neutralizing small areas of heart tissue responsible for electrical irregularities, thereby preventing the heart from generating irregular or abnormal rhythms. It is also applied in oncology, for example, in the treatment of breast and thyroid cancers, to destroy malignant cells. A key advantage of ablation therapy, especially when performed as the second stage of an electrophysiological study (EPS) in cardiac cases, is its potential to provide significant long-term improvement and often a definitive solution for patients, substantially restoring normal cardiac function.
