AbstractThe case of a female patient with symptomatic Wolff-Parkinson-White syndrome is presented with very late onset of symptoms at the age of 65 years, who had an apparent left-sided posteroseptal accessory pathway, which was ablated via a right-sided approach. A subepicardial location was strongly suspected within the coronary sinus ostium at the origin of the middle cardiac vein by applying both ECG and fluoroscopic criteria.
