Outcomes of catheter ablation of ventricular tachycardia with mechanical hemodynamic support: An analysis of the Medicare database

Introduction There is a paucity of data in favor of mechanical support during catheter ablation of ventricular tachycardia (VT). This study investigated the outcomes of VT ablation associated with mechanical support using percutaneous ventricular assist device (PVAD) versus intra‐aortic balloon pump...

Description
Summary:Introduction There is a paucity of data in favor of mechanical support during catheter ablation of ventricular tachycardia (VT). This study investigated the outcomes of VT ablation associated with mechanical support using percutaneous ventricular assist device (PVAD) versus intra‐aortic balloon pump (IABP). Methods and results We retrospectively examined the outcomes of patients who underwent VT ablation associated with PVAD versus IABP from 2010 to 2013, captured by the Medicare Inpatient Standard Analytic File database. Data from 345 patients (PVAD = 230, IABP = 115) were examined. On admission, the incidence of heart failure was higher in PVAD (84.3% vs. 73.0%; P = 0.01) with similar rates of renal failure in PVAD versus IABP (33.0% vs. 37.4%; P = 0.42). However, PVAD was associated with reduced in‐hospital cardiogenic shock (9.1% vs. 23.5%; P  <  0.001), renal failure (11.7% vs. 21.7%; P = 0.01), and length of stay (8.4 ± 7.9 vs. 10.6 ± 7.5; P
