  • Title: Utility of full electrophysiological study before accessory pathway ablation in Wolff-Parkinson-White syndrome.
    Author: Rosenbaum M, Klein GJ, Krahn A, Basta M, Le Feuvre C, Yee R.
    Journal: Can J Cardiol; 1997 Apr; 13(4):359-62. PubMed ID: 9141967.
    Abstract:
    BACKGROUND: A single catheter technique has been described for ablation in patients with Wolff-Parkinson-White syndrome. It is unknown how often omission of a standard electrophysiological study would lead to misdiagnosis based on an assumption that the manifest accessory pathway is responsible for clinical tachycardia. OBJECTIVES: To examine the contribution of the standard electrophysiological study versus an abbreviated, single catheter approach in patients with Wolff-Parkinson-White syndrome and an overt delta wave electrocardiographically. PATIENTS AND METHODS: One hundred and fifty consecutive patients with a delta wave present on electrocardiogram referred for ablation had prior full diagnostic electrophysiological study. RESULTS: In 83% (124 of 150) of patients, the index accessory pathway was responsible for tachycardia and single catheter ablation would suffice. In 11% (17 of 150) of patients, the index pathway was not found to be the culprit producing tachycardia and in another 6% (nine of 150) additional information was obtained from electrophysiological study with possible clinical significance. CONCLUSIONS: Omission of the full diagnostic electrophysiological study is acceptable in the majority of patients presenting with a delta wave on electrocardiogram. However, important clinical information is missed in a sizeable minority of patients.
