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 admissons with CCS 0 and during non-elective admissions in pts with CCS ≥2 (Table 2). The increase in complications was greater during non-elective admissions (slope 1.79 vs 0.7; p = 0.042).
Conclusions: SVT CA during elective admissions was associated with lower complication rates. The complexity of pts undergoing CA has increased from 2000-2012 and there was an increasing complications rate, particularly among pts with CCS ≥2 during non-elective admissions. This raises the question whether pts with SVT during non-elective admission should be stabilized and scheduled for elective CA on future hospitalization.
