Abstract:
A 9-year-old boy had refractory supraventricular tachycardia and a right atrial (RA) diverticulum as diagnosed by ultrafast computed tomography. An electrophysiological study under transesophageal echocardiography guidance revealed a concealed right anterior accessory pathway passing through the body of the RA diverticulum. Radiofrequency ablation was performed to eliminate retrograde ventriculoatrial conduction.
