Principles and Safety of Radiofrequency and Cryo Ablation

Abstract

Radiofrequency ablation (RFA) is a particular form of radiofrequency electrosurgery that takes advantage of the ability of radiofrequency alternating current to create heat in biologic tissue. RFA is used for the destruction of unwanted tissue in many medical specialties including cardiology, urology, thoracic surgery, and oncologic surgery. The ability of radiofrequency current to ablate tissue is variable and greatly depends on the tissue to be ablated and the properties of the tissue in which the target lesion is embedded. Several safety issues need to be considered including potential injuries to the operator and patient as well as safety concerns with regard to the effectiveness of RFA. Many different proprietary systems are currently available, and it is important that the user of a particular system is very familiar with its particular properties, use, and application algorithms.
