Radiofrequency ablation (RFA) is a minimally invasive procedure that destroys cancerous tumors. Pulses of radiofrequency energy are sent through a catheter (a long, thin tube) to heat and destroy diseased tissue. Currently, RFA is a standard treatment for patients with inoperable liver tumors.
Radiofrequency (RF) catheter ablation (RFCA) has revolutionized treatment for tachyarrhythmias and has become first-line therapy for some tachycardias. Although developed in the 1980s and widely applied in the 1990s, formalized guidelines for its use in clinical practice were not developed until some years later.
