[Local features of electrophysiologic and epicardial mapping of posterior septal accessory pathways in patients with surgically corrected preexcitation syndrome].
Posterior septal accessory pathways were documented in 6 patients with preexcitation syndrome who underwent detailed electrophysiologic evaluation and epicardial mapping. All 6 patients were cured by surgical ablation of accessory atrioventricular pathway. After follow-up of 9 months on average, 6 patients remain cured. No patient had recurrent supraventricular tachycardia and none had persistent atrioventricular conduction disturbance. The results of electrophysiologic study and epicardial mapping showed local characteristics of posterior septal accessory pathways. Accurate localization of posterior septal accessory pathways is very important in raising the rate of success in operation.
