Abstract

To compare the utilization and outcomes in patients who had percutaneous coronary interventions (PCIs) performed with intra-aortic balloon pump (IABP) versus percutaneous ventricular assist devices (PVADs) such as Impella and TandemHeart and identify a sub-group of patient population who may derive the most benefit from the use of PVADs over IABP. Despite the lack of clear benefit, the use of PVADs has increased substantially in the last decade when compared to IABP. We performed a cross sectional study including using the Nationwide Inpatient Sample. Procedures performed with hemodynamic support were identified through appropriate ICD-9-CM codes. We identified 18,094 PCIs performed with hemodynamic support. IABP was the most commonly utilized hemodynamic support device (93%, n = 16, 803) whereas 6% (n = 1069) were performed with PVADs and 1% (n = 222) utilized both IABP and PVAD. Patients in the PVAD group were older in age and had greater burden of co-morbidities whereas IABP group had higher percentage of patients with cardiac arrest. On multivariable analysis, the use of PVAD was a significant predictor of reduced mortality (OR 0.55, 0.36-0.83, P = 0.004). This was particularly evident in sub-group of patients without acute MI or cardiogenic shock. The propensity score matched analysis also showed a significantly lower mortality (9.9% vs 15.1%; OR 0.62, 0.55-0.71, P < 0.001) rate associated with PVADs when compared to IABP. This largest and the most contemporary study on the use of hemodynamic support demonstrates significantly reduced mortality with PVADs when compared to IABP in patients undergoing PCI. The results are largely driven by the improved outcomes in non-AMI and non-cardiogenic shock patients.
