Intraoperative monitoring of myocardial oxygenation during open-heart surgery: feasibility and initial performance

Abstract Myocardial protection during cardiopulmonary bypass relies on intermittent administrations of cardioplegia without continuous, tissue‑level feedback on myocardial oxygen supply and mitochondrial metabolic status. Extended near‑infrared spectroscopy (eNIRS) can enable rea...
