High-risk patients with ventricular preexcitation -- a pendulum in motion

Article Abstract:

Radiofrequency catheter ablation treatment may be effective for treating Wolff-Parkinson-White syndrome even if the patient has no symptoms, according to a study published in 2003. Other studies have shown that these patients have a low risk of sudden death from a severe arrhythmia. So many doctors decided not to treat them. This study shows that this decision may need to be reconsidered.
