[A new method to evaluate myocardial preservation techniques (author's transl)].
Nuclear magnetic resonance (NMR) is a non-invasive technique which, when using 31Phosphorus (as is usually the case), provides sequential determinations of the concentrations of high energy phosphate compounds and of intracellular pH in tissues subjected to electro-magnetic pulses. NMR can now be applied to the whole heart and makes it possible to record simultaneously biochemical and haemodynamic data. Referring to personal cases, the authors emphasize the value of NMR as a new device for evaluating myocardial preservation techniques during both ischaemia and reperfusion.
