[Radiofrequency ablation of supraventricular tachycardia].
Most forms of supraventricular tachycardia are based on a reentry-mechanism which is maintained by a specific anatomic substrate (e.g., dual AV-nodal physiology, accessory pathway). Since this substrate is usually a very localized and well defined anatomical abnormality, focal thermocoagulation by radiofrequency energy is highly effective in restoring normal physiology, thereby offering definite cure to a high percentage of these patients. The present article summarizes pathophysiologic mechanisms as well as diagnostic electrophysiologic testing- and ablation-techniques. Clinical success and complications are discussed in the light of current indications for elective radiofrequency ablation of supraventricular tachycardias.
