    Abstract:
    We present a case of successful surgical ablation of an oblique epicardial accessory pathway on the right coronary artery in a 56-year-old female patient with Wolff-Parkinson-White (WPW) syndrome, for which the radio-frequency (RF) catheter ablation had not been effective 3 times. The heart was exposed via a T-shaped sternotomy, and positioned for adequate exposure using a suction device. Epicardial mapping was performed with a multi-electrode catheter fixed on the atrioventricular sulcus. The epicardium just above the right coronary was dissected with an ultrasonic scalpel and we confirmed complete electrophysiological block of the accessory pathway. For 3 years since the surgery, there has been no recurrence of arrhythmia in the patient. Although an RF ablation through a transcutaneous intrapericardial approach can be an alternative, surgical ablation seems to be a safer and more curative approach to failed RF catheter ablation of accessory pathway. Such surgical skills should be maintained.
