Recurrence rate after accessory pathway ablation.

OBJECTIVE To evaluate characteristics of patients and accessory pathways as well as additional technical factors involved in the reappearance of accessory pathway conduction after successful ablation. DESIGN Analysis of recurrences after radiofrequency ablation. SETTING 163 consecutive patients with 167 accessory pathways. SUBJECTS 97 men and 66 women with a mean (SD) age of 36 (14) range...

Factors associated with recurrence of accessory pathway conduction after radiofrequency catheter ablation.

Catheter ablation of 215 accessory pathways (APs) using radiofrequency current (RF) was attempted in 204 consecutive patients. Two hundred twelve of the 215 (99%) APs were successfully ablated. After a minimum of follow-up period of 1 month (mean 8.5 +/- 5.4 months), AP conduction had returned in 17 patients (8%). Recurrence of AP conduction was manifest by atrioventricular (AV) reentrant tachy...

Shortening of ventriculoatrial interval after ablation of an accessory pathway

A 21-year old man with history of 8 year palpitation was referred for electrophysiologic study and possible radiofrequency ablation. Physical examination and transthoracic echocardiographic study did not disclose any abnormality. Baseline ECG showed normal sinus rhythm with normal PR and QRS intervals and no evidence of preexcitation. Antiarrhythmic drugs (propranolol and verapamil) were discon...

Two cases of supraventricular tachycardia after accessory pathway ablation.

Case Presentation No. 1 A 52-year-old man was referred for recurrent palpitations after 2 prior electrophysiology studies and ablations at an outside institution targeting right anteroseptal and left posterolateral accessory pathways (AP) for orthodromic reentrant tachycardia (ORT). Baseline ECG revealed sinus rhythm without preexcitation and an incomplete right bundle branch block. An ECG from...

Role of slow pathway after nodal fast pathway ablation on the basic and rate- dependent properties of the isolated rabbit atrioventricularNode

  Introduction : The aim of this study is to obtain new insight into possible relation between functional properties of slow concealed pathway and rate-dependent properties of AV-node.   Methods : Rate-dependent nodal properties of recovery, facilitation, and fatigue were characterized by stimulation protocols in one groups of (N=7) isolated superfused AV-Nodal rabbits. Small miniature lesions ...
