Abstract

The existence of accessory pathways connecting right atrial appendage (RAA) and right ventricular outflow tract (RVOT) is well established. We present a case where an accessory pathway of this type mimicked parahisian pathway. Ultimately, preprocedural computed tomography (CT) was helpful in planning the procedure and accomplishing successful ablation after a failed attempt.
