Introduction Pulmonary vein automaticity is an established trigger of paroxysmal atrial fibrillation (PAF) making pulmonary vein isolation (PVI)  the cornerstone for catheter ablation. However, data on triggers of AF and catheter ablation strategy in very young (<30 years old) patients are sparse. Methods and results: Sixteen young patients (mean age 25.2 ± 4.9 years; 75% men) with recurrent drug refractory PAF underwent EP study and ablation at 3 EP centers. None of the patients had structural heart disease or family history of AF. EP study revealed degeneration of induced supraventricular tachycardia (SVT) into AF in 5 patients (n = 5, 31.2%). Induced SVTs were left lateral concealed accessory pathway mediated orthodromic AVRT in two patients, typical AVNRT in two patients, and left superior PV tachycardia in one patient respectively. In patients with induced SVTs, SVT ablation without PVI was performed as an index procedure. Remaining patients underwent second generation cryoballoon (CB-2) based PVI (n = 11, 68.7%). There were no major complications related to ablation procedures. Follow-up was based on outpatient visits including 24-h Holter-ECG at 3, 6 and, 12 months post ablation, or additional Holter-ECG was ordered in case of symptoms suggesting recurrence. Recurrence was defined as any atrial tachyarrhythmia (ATA) episode >30s following a 3-month blanking period. After a median follow-up of 18.3 ± 6.2 months, 13 of 16 (81.2%) patients were free of ATA recurrence. None of the patients belonging to SVT ablation only group experienced ATA recurrence. Three patients with previous CB-2 PVI recurred, one had typical atrial flutter and underwent CTI ablation, remaining 2 patients had AF recurrence and medically followed. Conclusion In a considerable fraction of young adult patients with history of PAF SVTs may be responsible and SVT ablation without PVI may be sufficient as an index procedure. Catheter ablation AF seems to be safe and effective in this population.

Background/Aim. The occurrence of atrial fibrillation (AF) in the presence of an accessory pathway (AP) that conducts rapidly is potentially lethal because the rapid ventricular response may lead to ventricular fibrillation (VF). The aim of the study was to determine long-term efficacy of AP catheter-ablation using radiofrequency (RF) current in secondary prevention of VF in WPW patients. Methods. Study included a total of 192 symptomatic WPW patients who underwent RF catheter-ablation of AP in our institution from 1994 to 2007 and were available for clinical follow-up for more than 3 months after procedure. Results. Before ablation, VF was recorded in total of 27 patients (14.1%). In 14 of patients (51.9%) VF was the first clinical manifestation of WPW syndrome. A total of 35 VF episodes were identified in 27 patients. The occurrence of VF was preceded by physical activity or emotional stress in 17.1% of cases, by alcohol abuse in 2.9% and by inappropriate intravenous drug administration in 28.6%. In addition, no clear precipitating factor was identified in 40% of VF cases, while informations about activities preceding 11.4% of VF episodes were not available. The follow-up of 5.7 ? 3.3 years was obtained in all of 27 VF patients. Of the 20 patients who underwent successful AP ablation, all were alive, without syncope or ventricular tachyarrhythmias during long-term follow-up. In 4 of 7 unsuccessfully treated patients, recurrence of supraventricular tachycardia and/or preexcited atrial fibrillation were recorded; one of these patients suddenly died of VF, 6 years after procedure. Conclusion. In significant proportion of WPW patients, VF was the first clinical manifestation of WPW syndrome, often precipitated by physical activity, emotional stress or inappropriate drug administration. Successful elimination of AP by percutaneous RF catheter-ablation is highly effective in secondary prevention of life-threatening tachyarrhythmias in patients with ventricular preexcitation.

AbstractBackgroundTo compare potential risk factors for complications and recurrence after radiofrequency catheter ablation in symptomatic atrioventricular reentrant tachycardia in children and adolescents.MethodsWe retrospectively reviewed the data of 213 consecutive patients with symptomatic atrioventricular reentrant tachycardia who underwent both electrophysiological study and radiofrequency catheter ablation, divided these patients into two groups, children (age <12 years) and adolescents (12 ≤ age < 18 years), and compared the location of the accessory pathway, success rate, recurrence rate, complications, presence of congenital heart disease, presence of intermittent ventricular pre-excitation, and presence of Wolff–Parkinson–White syndrome in the two groups.ResultsThe position of the accessory pathway was mostly right sided in children (61.3%) and left sided in adolescents (61.5%). Children had significantly more congenital heart disease than adolescents (6.4% versus 0.8%). Univariate analysis showed children or adolescents with right-sided accessory pathways to be 6.84 times and those with accessory pathways on both sides of the septum 25 times more likely to relapse than those with a single accessory pathway. Multivariate analysis indicated that children or adolescents with two accessory pathways were six times, and those with intermittent ventricular pre-excitation nine times more at risk of relapsing following radiofrequency ablation than those with single accessory pathways. All five complications occurred in children.ConclusionsThe findings suggest that the position and number of accessory pathways and presence of intermittent ventricular pre-excitation are related to risks of recurrence of atrioventricular reentrant tachycardia in children and adolescents.
