Atrial Fibrillation Management and Outcomes

Wolff-Parkinson-White (WPW) syndrome can be associated with disabling and life-threatening dysrhythmias that are resistant to medical treatment yet are amenable to surgical treatment. This report relates our experience with 10 Type A and 10 Type B patients who have been treated by surgery. The operation has evolved from one procedure, applicable to only a few patients, to a new procedure which allows the chance for cure for nearly all patients. By the old method, the Kent bundle was sectioned from the ventricular side; now it is divided from the atrial side, an approach which allows access to the septal tracts. There have been twelve cures, four partially successful operations, and four failures. In one failure, correction of a Type B lesion in the septal area was attempted via the old operation. In a second failure, WPW was associated with Ebstein's anomaly. In the other two failures, the Kent bundle entered the left side of the ventricular septum from the atrial septum at a point adjacent to the atrioventricular (AV) node and His bundle. This group, atrial septal Type A, may require His bundle division as well as Kent bundle division. All other patients with WPW can be cured by properly planned and performed operations.
