Only a small percentage of patients with WPW syndrome (<1%) are at risk for sudden cardiac death (SCD). In patients who present with preexcited AF, cardiac electrophysiologic studies and radiofrequency (RF) catheter ablation may be curative. Other presentations include symptomatic SVT, which can also be cured by catheter ablation. Asymptomatic patients need periodic observation. The onset of cardiac arrhythmias, and possibly the sudden death risk, may be eliminated by prophylactic catheter ablation as well. [8]

This review discusses the pathogenesis, clinical presentation, evaluation, and treatment of patients with WPW syndrome.
