Radiofrequency Catheter Ablation of a Coronary Sinus‐Ventricular Accessory Connection in Dextrocardia with Complete Situs Inversus and an Anomalous Inferior Vena Cava

An anomalous inferior vena cava (IVC) is often associated with patients with dextrocardia. However, radiofrequency catheter ablation in such a case with that combination has not been reported. We encountered a case of Wolff‐Parkinson‐White syndrome with dextrocardia associated with complete situs inversus and an azygos continuation of the IVC. A steep angulation at the junction of the azygos vein and superior vena cava precluded the precise mapping of the anatomical right cavity with a femoral vein approach. Successful catheter ablation of an accessory connection between the coronary sinus and left ventricle could be achieved with a right cubital vein approach.

Efficacy of Electroanatomical Mapping for Radiofrequency Ablation of Right-sided Accessory Pathways

Introduction: Due to the difficulty in performing detailed mapping around the tricuspid annulus and the high occurrence of mechanical trauma during the procedure, the outcome of right‐sided accessory pathway (AP) ablation still has a relatively high primary failure and recurrence rate.
