Myocardial tissue pH and myocardial temperature tracings from a patient who underwent mitral valve replacement and coronary artery bypass grafting. (A) Myocardial tissue pH and myocardial temperature tracings obtained throughout procedure. (B) Myocardial tissue pH corrected to 37°C. Horizontal bars depict times and routes of cardioplegia administration. (ApH = anterior wall pH; AR = aortic root; AT = anterior wall temperature; BP = cardiopulmonary bypass; DEFIB = defibrillation; LAD = left anterior descending coronary artery; OMB = obtuse marginal coronary artery; PpH = posterior wall pH; PT = posterior wall temperature; XC = aortic cross clamp.)

Myocardial tissue pH and myocardial temperature tracings from a patient who underwent aortic valve replacement and coronary artery bypass grafting. (A) Actual myocardial tissue pH and myocardial temperature tracings throughout procedure. (B) Myocardial tissue pH corrected to 37°C. (ApH = anterior wall pH; AR = aortic root; AT = anterior wall temperature; BP = cardiopulmonary bypass; DEFIB = defibrillation; LM = left main coronary artery; PpH = posterior wall pH; PT = posterior wall temperature; RCA = right coronary artery; XC = aortic cross clamp.)
