Description

Calcification of implanted biological heart valves leads to malfunction after a certain period. The substance mainly responsible for accumulated calcium deposits in glutaraldehyde. The study was divided into was phases: chemical detoxification of the tissue by glutaraldehyde extraction to minimize calcification, and subsequent PIXE analysis of more than 8 aortic wall samples to examine the efficiency of the detoxification process.
