Wolff-Parkinson-White Syndrome: Symptom-Free Is Not Risk-Free

Mayo Clinic pediatric cardiologist and electrophysiology specialist Bryan Cannon, M.D., along with cardiologist Bernard Gersh, M.B., Ch.B., D.Phil., discuss Wolff-Parkinson-White (WPW) Syndrome in asymptomatic patients.

Wolff-Parkinson-White is a syndrome in which an extra electrical pathway between the upper and lower chambers of the heart causes a rapid heartbeat. WPW is relatively common and with increased screening for athletics and attention-deficit/hyperactivity-disorder, more patients are being diagnosed and treated. It is important for patients, even those with no symptoms, to be treated as there have been a small percentage of asymptomatic patients where sudden cardiac death has occurred. Treatment can include a transesophageal study or an electrophysiology study and cardiac ablation. Advances in technology, high success rates, and very low complication rates make treating asymptomatic WPW patients desirable.
