An evaluation was carried out of twelve consecutive patients undergoing combined aortic and mitral valve replacement.
Combination of cold cardioplegia and intrapericardial cooling mat was used for myocardial preservation during ischemic arrest. Such Combination bring the septal temperature to near 10°C and keep low temperature of 7-15°C effectively. The Cpk-MB level was slightly high in this group as compared AVR or MVR group., Two operative death did not correlate with this myocardial protection. Postoperative course of another ten patients was satisfactory. The results of this study support the safety of prolonged cardioplegic arrest under low myocardial temperature in combined aortic and mitral valve replacement
