Accessory Pathway Ablation in a Patient with Situs Inversus Totalis and Wolff-Parkinson-White Electrocardiographic Pattern: Mirror Approach

A 47-year-old asymptomatic male public driver with situs inversus totalis and Wolff-Parkinson-White electrocardiographic pattern (Fig. 1a) was referred to our arrhythmia center for electrophysiologic study. A decapolar coronary sinus catheter was introduced via the right femoral vein and positioned in the coronary sinus on the right anterior oblique projection. Intracardiac electrograms showed the earliest ventricular activation with a 25ms ventricular potential-delta interval and no isoelectric interval between atrial and ventricular potentials on the distal bipole of the catheter suggesting a lateral free wall accessory pathway.
