Radiofrequency Ablation of a Concealed Right Anterior Accessory Pathway Associated with Right Atrial Diverticulum in a Child

CHIU, S.N.,et al.: Radiofrequency Ablation of a Concealed Right Anterior Accessory Pathway Associated with Right Atrial Diverticulum in a Child. 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
