[Myocardial protection from cardioplegic and hypothermia during aortic cross-clamping (author's ttrans)].

The clinical results with cardioplegic solutions and hypothermia during aortic cross-clamping are compared with the clinical results obtained with hypothermia only. To complete the study miocardial biopsies were obtained during aortic cross-clamping in order to evaluate the concentration of ATP and CPK. The obtained data confirm the effectiveness of the myocardial protection.
