Risk to Patients From Radiation Associated With Radiofrequency Ablation for Supraventricular Tachycardia

Abstract

Prolonged fluoroscopy during radiofrequency ablation may potentially cause a small increase in the lifetime risk of fatal malignancy, with lung malignancy being most likely. This risk is small only with the use of techniques and x-ray equipment optimized to keep radiation as low as possible. The risk is increased in obese patients.
