Surgical Treatment of Wolff-Parkinson-White Syndrome Combined with AV Nodal Reentrant achycardia in a Patient with Ebstein`s Anomaly - A report of one case -

Ebstein씨 심기형에 동반된 Wolff-Parkinson-White 증후군 및 방실결절 회귀성 빈맥에 대한 수술치험 1례 보고

A 17 year old female patient with Ebstein`s anomaly received surgical treatment for WPW syndrome and AV nodal reentrant supraventricular tachycardia[SVT] Electrophysiologic study revealed that an anomalous pathway was located in the right posterolateral portion and antegrade dual AV nodal pathway responsible for AV nodal reentrant tachycardia. The patient was underwent surgery on February 18, 1987. Intraoperative mapping was used to define the location of accessory pathway. The accessory pathway was cryoablated through the epicardium. Simultaneously discrete cryoablation around the perinodal area was performed to prevent AV nodal reentrant SVT. The atrialized right ventricle of Ebstein`s anomaly was plicated with 11 pledget mattress sutures under the cardiopulmonary bypass. Two and half years after surgery, the patient has no evidence of WPW syndrome or supraventricular tachycardia.
