The cVAD registry for percutaneous temporary hemodynamic support: A prospective registry of Impella mechanical circulatory support use in high-risk PCI, cardiogenic shock, and decompensated heart failure

Abstract

Management of patients requiring temporary, mechanical hemodynamic support during high- risk percutaneous coronary intervention (PCI) or in cardiogenic shock is rapidly evolving. With the availability of the Impella 2.5, CP, 5.0, LD, and RP percutaneous mechanical circulatory support devices, there is a need for continued surveillance of outcomes. Three factors underline the importance of a registry for these populations. First, large randomized trials of hemodynamic support, involving cardiogenic shock, are challenging to conduct. Second, there is increasing interest in the use of registries to provide real-world experience and to allow the flexibility to evaluate individual patient uses and outcomes. Third, current, large databases have not captured the specific impact of mechanical support treatment of cardiogenic shock. The predecessor to the catheter-based ventricular assist devices registry, known as USpella, began in 2009 with paper data acquisition but beginning in 2011 transferred to electronic data capture, enrolling 3,339 patients through 2016. Throughout, registry data have been used to assess the outcomes of Impella therapy, leading to 8 publications and 4 Food and Drug Administration premarket approvals covering multiple indications and Impella devices. Going forward, the registry will continue to assess not only in-hospital outcomes but long-term follow-up to 1 year. In addition, data management will be enhanced to assess quality and clinical experiences. The registry will also provide a mechanism for postmarketing surveillance. This manuscript reviews the ongoing catheter-based ventricular assist devices registry design, management, and contributions of the registry data. The upgraded registry will provide a more robust opportunity to assess acute and late outcomes of current and future device use worldwide. CONDENSED ABSTRACT: The current catheter-based ventricular assist devices registry is an international database documenting outcomes with temporary Impella hemodynamic support. The registry has supported 8 publications and 4 Food and Drug Administration premarket approvals since its inception in 2009. The current registry is more robust containing outcomes up to 1 year postprocedure
