Corrected transposition with severe intracardiac deformities with Wolff-Parkinson-White syndrome in a child. Electrophysiologic investigation and surgical correction.

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...

Radiofrequency catheter ablation in a child with Wolff-Parkinson-White syndrome and congenitally corrected transposition of the great arteries.

The case is presented of a five-year-old boy with Wolff-Parkinson-White syndrome, who had undergone three surgical palliations because of congenitally corrected transposition of the great arteries, ventricular septal defect and pulmonary trunk near-atresia. Successful and uncomplicated radiofrequency catheter ablation of an accessory pathway located across the systemic atrioventricular valve ri...

Intracardiac recording by catheter electrode of accessory pathway depolarization.

At electrophysiologic study in a patient with the Wolff-Parkinson-White syndrome, intracardiac catheter recordings demonstrated a deflection that occurred 30 ms before ventricular activation. The rapid deflection was present during ventricular preexcitation but not during normal atrioventricular conduction. All QRS complexes were preexcited to varying degrees during atrial fibrillation, yet the...

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

Electrophysiologic characterization and postnatal development of ventricular pre-excitation in a mouse model of cardiac hypertrophy and Wolff-Parkinson-White syndrome.

OBJECTIVES We sought to characterize an animal model of the Wolff-Parkinson-White (WPW) syndrome to help elucidate the mechanisms of accessory pathway formation. BACKGROUND Patients with mutations in PRKAG2 manifest cardiac hypertrophy and ventricular pre-excitation; however, the mechanisms underlying the development and conduction of accessory pathways remain unknown. METHODS We created tr...
