Accessory AV Connection Between RAA and RV. A 24‐year‐old woman had experienced frequent attacks of orthodromic AV reciprocating tachycardia. The polarity of the delta waves suggested a right anterior or anterolateral accessory pathway. After ablation at the tricuspid annulus was unsuccessful, earliest retrograde atrial activation was recorded on the floor of the right atrial appendage, 2 cm above the tricuspid ring. Application of radiofrequency en‐ergy at this site aholished accessory pathway conduction. This unusual accessory pathway, located between the floor of the right atrial appendage and the right ventricle, was amenable to radiofrequency catheter ablation from within the right atrial appendage.
