Conditions
Keywords
Postconditioning, cyclosporine A, myocardial ischemia, cardiac surgery, aortic valvulopathy
Brief summary
Primary objective: To evaluate the efficacy of the cyclosporin A administration to induce a cardioprotection during the valvular surgery.
Interventions
a single bolus of 2.5 mg/kg, administered before aortic cross-declamping
No cyclosporine A is administered before aortic cross-declamping.
