IMPELLA, Complications and Tolerance

Sponsor: University Hospital, Montpellier

Summary

Myocardial infarction complicated by cardiogenic shock (AMICS) is associated with high morbidity and mortality, and devices like Impella® CP and Impella 5.0-5.5 are often used for hemodynamic support, either alone or combined with veno-arterial ECMO (ECMELLA). While recent studies suggest improved survival with Impella® in cardiogenic shock, complications remain common, particularly due to deep arterial access and the need for anticoagulation. Hemocompatibility-related adverse events (HRAEs) such as ischemia, bleeding (44%), hemolysis (32%), and stroke (13%) frequently occur. Achieving hemocompatibility between the patient's blood and the device is challenging, as pump flow, anticoagulation, and patient factors contribute to both thrombotic and hemorrhagic complications. Despite advances, further research is required to better understand and reduce these risks in clinical practice.
