D-PO06-117 - In-hospital Outcomes Of Ventricular Tachycardia Ablation In Patients With Ischemic And Non-ischemic Cardiomyopathy (ID 1369)


Background: Pathophysiology of Ventricular Tachycardia (VT) is different in patients with Ischemic cardiomyopathy (ICM) compared to non-ischemic cardiomyopathy (NICM). There are limited outcomes data in these groups, especially during the index hospitalization.
Objective: Compare In-hospital outcomes in patients with Ischemic and Non-ischemic cardiomyopathy undergoing VT ablation.
Methods: Data were obtained from the 2012-2015 NIS databases, sponsored by Agency for Healthcare Research and Quality as a part of Healthcare Cost and Utilization Project. SAS was used to perform data analysis. We compared patients with ICM and NICM undergoing catheter ablation. Outcomes from these cohorts were compared to assess differences in periprocedural complications and mortality.
Results: A total of 1,36,078 patients were hospitalized with the principal diagnosis of VT during study period. 1055 patients with ICM and 1150 patients with NICM underwent catheter ablation for VT. Death occurred in 37/1055 (3.51%) patients with ICM and 28/1150 (2.43%) in NICM (P 0.1370). Vascular complications occurred in 18/1055 (1.71%) and 18/1150 (1.57%) patients in ICM and NICM group (P 0.7942). Iatrogenic complications occurred in 26/1055 (2.46%) and 27/1150 (2.35%) patients in ICM and NICM group (P 0.8582). Periprocedural MI occurred in 55/1055 (5.21%) and 44/1150 (3.83%) patients in ICM and NICM group (P 0.1161). Pericardial complications occurred in 26/1055 (2.46%) and 51/1150 (4.43%) patients in ICM and NICM group(P 0.0118).
Conclusion: In patients with Ischemic and Non-ischemic Cardiomyopathy undergoing ventricular tachycardia ablation mortality rate is not significantly different.
