Radiofrequency catheter ablation: the first decade.

Radiofrequency catheter ablation (RFCA) has become a safe and effective procedure for treatment of supraventricular and ventricular arrhythmia in children and adults. Anatomic data and mapping experience obtained from surgical and direct current ablation procedures paved the way for radiofrequency ablation. Radiofrequency energy is a power source well suited to place focal catheterization lesions. A large variety of supraventricular tachycardias can be successfully cured with a high success rate with minimal complications. Also, a growing number of ventricular tachycardias can be cured or palliated with this procedure. Ongoing research may increase the scope of this procedure to provide primary cures for atrial fibrillation and ventricular tachycardia associated with coronary artery disease. These procedures are highly complex and should be performed in a high-volume center.
