Abstract

OBJECTIVES: Cardiogenic shock carries high mortality despite advancements in therapeutic interventions. Impella (Abiomed) is a mechanical circulatory support device that is being increasingly used in cardiogenic shock patients. Impella is also utilized in high-risk patients undergoing percutaneous coronary intervention (PCI). We review the trend of Impella use at a single tertiary-care center, retrospectively analyze the outcomes, and discuss the increasing use of this device in the United States.

METHODS: This a retrospective, observational study of Impella use for two indications, cardiogenic shock and high-risk PCI, at a tertiary-care center. The primary endpoint was the yearly implant rate of Impella and the secondary endpoint was periprocedural complications and major adverse cardiovascular events at 30 days.

RESULTS: Forty-four Impella devices were implanted between 2008 and June of 2017. The rate of Impella implantation has significantly increased since its introduction in our facility in 2008. The most common complication was acute renal dysfunction (23%) followed by vascular complications (20%). Mortality at 30 days was 75% in the cardiogenic shock group and 11% in the high-risk PCI group.

CONCLUSION: The use of the Impella device as a mechanical circulatory support has increased since its introduction, although its acceptance rate remains low. Despite its theoretical hemodynamic advantage, the outcome in cardiogenic shock patients remains poor.
