RADIOFREQUENCY ABLATION OF AN ACCESSORY PATHWAY IN A PATIENT WITH CORRECTED EBSTEINS-ANOMALY

Ebstein's anomaly of the tricuspid valve has a known association with the Wolff-Parkinson-White syndrome. Radiofrequency ablation has become the treatment of choice for the latter, but there have been no report s of the feasibility of this procedure after tricuspid valve replaceme nt. We present a patient who first exhibited evidence of intermittent preexcitation and associated symptomatic arrhythmia 9 years after tric uspid valve replacement for Ebstein's anomaly, and describe the challe nges posed by this case.
