[Temporary circulatory assistance by Impella™ in interventional cardiology: Observational study and medico-economic assessment after four years of use].

Objectives: During life-threatening emergencies or risky cardiologic interventions, pharmacology can be limited and the use of appropriate medical devices is then necessary. The Impella™ catheter, CP and 2.5, has been referenced for the exclusive use of the interventional cardiology technical platform at Hôpital Nord (AP-HM) in the absence of rapid access to the Extracorporeal Circulation unit.

[Causality analysis of a low-viscosity bone cement in orthopaedic surgery following serious adverse events].

Objectives: Low-viscosity bone cement impregnated with gentamicin is frequently used to fix femoral prostheses. Three cardiac arrests occured successively during cementoplasty oh hip replacements, leading to the death of two patients. The objective of this study is to describe the actions undertaken to establish a potential link between the use of the bone cement and the occurrence of these serious adverse events (SAE).
