A five month old boy was referred to us with recurrent episodes of tachycardia and heart failure due to WPW syndrome. ECG and electrophysiological studies revealed a left lateral wall accessory conduction pathway. The patient did not respond to medical treatment and the division of the accessory pathway was performed by epicardial cryoablation methods through left lateral thoracotomy without using cardio-pulmonary bypass. Tachyarrhythmia and delta wave disappeared immediately following the operation and the patient had uneventful postoperative recovery. In this paper, the usefulness of epicardial cryoablation with left lateral thoracotomy for infants with a proved left accessory conduction pathway is stressed.
