OUTCOMES OF CATHETER ABLATION FOR SUPRAVENTRICULAR TACHYCARDIA IN ADULT PATIENTS WITH CONGENITAL HEART DISEASE

Background: Supraventricular tachyarrhythmias (SVT) are common in adult patients with congenital heart disease (CHD). There is paucity of data regarding the safety and outcomes associated with catheter ablation in these patients. Methods: We queried the National Inpatient Sample (NIS) to identify all adults patients \u3e 18 years with CHD undergoing catheter ablation for SVT. Results: Between 2003-2013, 5,966 patients with CHD underwent catheter ablation for SVT. Of these 4,769 were performed for atrial fibrillation or atrial flutter and rest for other SVTs. The mean age of these patient was 47+/- 15 years, 59.9% were males. 18% of patients experienced procedure related complications, however life-threatening complications were infrequent (3.8%) (Table1). On multivariate analysis, older age (OR= 1.016; CI= 1.008-1.023; P Conclusion: Patients with CHD undergo catheter ablation for SVT at young age. One-fifth of the patients experienced in-hospital complications while in-hospital death were rare
