Outline of Final Research Achievements |
There is an increasing number of domiciliary treatment cases of patients with severe heart failure. However, it is anticipated that the deterioration of peripheral organs might be caused by the long-term rotary blood pump support. We focused on the development of a new diagnostic method for the evaluation of peripheral perfusion using a simple non-invasive imaging. By the method designed, the colour level of intensity showed blood flow perfusion which could be validated in goats’ experiments with the laser Doppler flow velocimetry. Secondly, we examined the effect of mechanical circulatory assistance ratio on peripheral perfusion by the changes in revolution numbers during the left ventricular support using a centrifugal blood pump that was connected from the apex to the descending aorta. As a result, it was indicated the system designed in the study could be useful for the evaluation of peripheral circulatory condition during mechanical circulatory support.
