Outcomes in CArdiogenic SHock Patients Treated by MEchanical Circulatory suppoRt devicE : Impact of Shock Team

Short Term Mechanical Circulatory Support (STMCS) are the last resort therapeutics when refractory cardiogenic shock occurs. Growing technical possibilities like impella make the right choice at the right time challenging. At Bordeaux University Hospital, we have gathered the main protagonists which are the surgeon, the interventional cardiologist,and the intensivist as a shock team in January 2013. From that time, diagnosis of refractory cardiogenic shock triggers a multidisciplinary meeting driven by a common algorithm. The objective of this study is to perform a before-after comparison between decision of STMCS for refractory cardiogenic shock without shock team from january 2007 to january 2013 and after implementation of the shock team from April 2013 to April 2019.
