RESUMEN
OBJECTIVE: Catheter ablation following electrophysiologic study (EPS) is the mainstay of diagnosis and treatment for patients with atrioventricular reentrant tachycardia (AVRT), demonstrating excellent long-term outcome and a low rate of complications. In this study, our aim was to assess our experience in patients with accessory pathway (AP) and to compare our data with the literature. METHODS: We included 1,437 patients who were diagnosed and treated for AP in our hospital between 1998 and 2020. The demographic data of all the patients, AP location, and periprocedural results were recorded. RESULTS: Of the 1,437 patients, 1,299 (90.4%) were men; and the mean age of the population was 26.67 years. The location of 1,418 APs were along the left free wall (647 [45.6%] patients), in the posteroseptal region (366 [25.3%] patients), in the anteroseptal region (290 [20.4%] patients), and along the right free wall (115 [8.1%] patients). The ratio of the second AP existence was 3.0% and AVNRT co-existence was 2.0%. A total of 55 (3.8%) patients had recurrent sessions for relapse. Our center's total success rate was 95.5%, and total complication rate was 0.26%. CONCLUSION: According to our retrospective analysis, EPS is a highly functional tool in the diagnosis and management of arrhythmias such as AVRT for high-risk patient groups like military personnel with the aim of risk stratification and medical management.

Ventricular fibrillation in a patient with ventricular preexcitation is usually due to atrial fibrillation with an extremely rapid ventricular rate from which it degenerates. We present a case with Wolff-Parkinson-White syndrome and coexistent idiopathic ventricular fibrillation. The patient, a 23-year-old male, had had a cardiac arrest four years earlier. In electrophysiological study, the accessory pathway was located in the left posteroseptal region and successfully eliminated with radiofrequency catheter ablation. After the ablation procedure, ventricular fibrillation was induced with programmed ventricular stimulation. A dual chamber implantable cardioverter defibrillator was implanted in the patient.
