In radiofrequency ablation, what role does energy delivery play in tissue heating?

In radiofrequency ablation, the delivery of energy plays a critical role in tissue heating through the process of inducing molecular movement. When radiofrequency energy is applied to the targeted tissue, it causes charged particles within the tissue, such as ions, to oscillate. This movement increases the kinetic energy of the molecules, leading to a rise in temperature. The heat generated from this molecular agitation is essential for achieving the desired effects of ablation, which typically include tissue necrosis or coagulation.

In addition to its role in heating, the heat produced by radiofrequency ablation can also help in creating controlled lesions that effectively disrupt abnormal tissue or reduce blood flow to a specific area, but the primary mechanism through which energy delivery translates into therapeutic heating is the induction of molecular movement. This is why understanding the relationship between energy delivery and tissue temperature is vital for effective and safe ablation procedures.
