| Outline of Final Research Achievements |
Ischemic myocardial contracture (stone heart) occurs, if myocardial protection is not appropriate during cardioplegic arrest. For quantitatively monitoring a condition of myocardial protection, we have developed the stiffness sensor. To measure myocardial stiffness, negative pressure is applied to the myocardium through the probe and displacement of myocardial surface is quantified using ultrasonic pulse-echo.
In the future, we would evaluate this sensor in animal experimental models, and provide the cardiac surgery for clinical applications.
