Study Population
We want to include 50 patients, both women and men, undergo elective coronary bypass surgery or valve surgeon in CPB with moderate hypothermia.

Inclusion Criteria:

  • Patient age under 80.
  • Patients should undergo elective coronary artery bypass grafting surgery (ACB) or heart valve surgery (AVR or MVR).
  • The patient must be admitted at least 18 years of years.

Exclusion Criteria:

  • Damage to the frontal lobes corresponding to the area where SCO2 monitored.
  • Patients in pharmacological studies.
  • Patients with known intracranial vascular anomalies or cerebral aneurysms.
  • Patients with known neurological disease.
  • Patients with known undergone cerebral insult, TIA or carotid stenosis.
