The most important and effective factor for myocardial protection during cardiac operation is to keep the myocardium at as low a temperature as possible. The ideal temperature is around 15 degrees C. A thumbtack type of needle thermistor has been developed and used clinically and experimentally during myocardial protection. This type of needle thermistor has several definite advantages.
