Abstract 14104: Comparisons of Outcomes and Complication Rates Between Elective and Non elective Catheter Ablation for Paroxysmal Supraventricular Tachycardia

Aim: For patients (pts) with supraventricular tachycardia (SVT), it is unknown whether catheter ablation (CA) complication rates differ in pts during elective vs. non-elective admissions. Methods: The Nationwide Inpatient Sample was queried from 2000 to 2012 to identify pts undergoing SVT CA based on whether the admission was elective vs non-elective. Multivariate analysis was performed on all these pts and included Charlson Comorbidity Score (CCS), and other social/demographic data. Results: A total of 45,349 CAs were performed for SVT of which 53.4% were performed during elective admissions. On multivariate analysis, Table 1 shows factors, including elective admissions (OR 0.75; 95% CI 0.56-.98) independently associated with a lower rate of complications (including mortality). From 2000-12, the mean CCS increased from 0.42 to 1.03 for non-elective admissions and from 0.19 to 0.53 (slope 0.066 vs 0.032, p= 0.006) for elective admissions. An increase in complication rates was noted in pts during elective ...
