Protection of the heart against ischemic damage - Myocardial protection in isolated hearts with NMR during cardiac surgery: global myocardial ischemia. (joint study). - 24 hours preservation of the heart 'ex vivo' for cardiac transplantation. - Postischemic myocardial dysfunction and influence of inotropic drugs. - Isolated heart ischemia and influence of volatile anaesthesia. - Cardiopulmonary bypass techniques. - Isolated heart-perfusion techniques. - General hemodynamic measurements: pressure, flux, thermodilution, electrocardiogram. - Regional flow measurements with radioactive tracer microspheres (gamma counter). - Staining techniques based on extracorporeal perfusion of viabel and infarcted areas of the heart.
