Cardiac surgery is responsible for many complications. Microcirculation is involved in many of them. The objective of this study is to prospectively investigate the prognostic value of preoperative microcirculatory assessment in patients scheduled for cardiac surgery with CPB for the occurrence of postoperative complications. Microvascular dysfunction is suspected of being involved in postoperative psycho-cognitive decline. The influence of microcirculation on the evolution of psycho-cognitive assessment is also analyzed in this study.
Eligible patients are included during the preoperative assessment. Written consent is signed after complete explanation of the protocol. Patient characteristics as treatments, medical history, and EuroSCORE II are registered. Moreover, intraoperative data is collected. Psycho-cognitive and functional evaluation is made preoperatively. Microcirculation is evaluated for each patient before surgery. Complications are registered at the end of hospital stay. Psycho-cognitive and functional evaluation is repeated by call 30 days after the surgery.

Microcirculation will be evaluated for each patient before surgery with a laser speckle contrast imaging (LSCI) placed on the forearm. Tests will be performed for evaluation of endothelium reactivity: Iontophoresis.
