Surgery for Wolff-Parkinson-White syndrome: further experience with an epicardial approach.

An electrophysiologic approach to the surgical treatment of the Wolff-Parkinson-White syndrome. Report of two cases utilizing catheter recording and epicardial mapping techniques.

Radiofrequency catheter ablation in the treatment of Wolff-Parkinson-White syndrome

Introduction: Tachyarrhythmias in Wolf Parkinson White (WPW) syndrome, can be a life threatening factor. Antiarrhythmic drug therapy in this syndrome, has not been completely acceptable. Efficacy, safety and economy of Radio Frequency Catheter Ablation (RFCA) in western studies, has made it as the treatment of choice. In the present study, efficacy of RFCA in the ablation of accessory pathway...

Epicardial mapping in a variant of type A Wolff-Parkinson-White syndrome.

Electrocardiographic and epicardial mapping studies are reported in a child with an atrial septal defect and a variant of type A Wolff-Parkinson-White (WPW) syndrome. The vectorcardiogram suggested a posterior area of early activation and this was confirmed by epicardial mapping studies. Premature activation apparently occurred from a site near the endocardium of the basal region of the left ve...

Surgical correction of anomalous left ventricular pre-excitation: Wolff-Parkinson-White (type A).

This report describes two patients with the Wolff-Parkinson-White syndrome including episodes of supraventricular tachycardia and atrial fibrillation. Both patients had Type A electrocardiograms. Electrophysiological studies demonstrated pre-excitation and evidence that the site of preexcitation involved the left ventricle. The effective refractory periods of the accessory pathway during atriov...

Phase analysis in the Wolff-Parkinson-White syndrome with surgically proven accessory conduction pathways: concise communication.

Twenty-one patients with the Wolff-Parkinson-White (WPW) syndrome who underwent surgical division of the accessory conduction pathway (ACP) were studied by gated blood-pool scintigraphy. In each case, a functional image of the phase was generated, based on the fundamental frequency of the Fourier transform. The location of the ACP was confirmed by electrophysiologic study, epicardial mapping, a...
