Abstract
Calcification of implanted biological heart valves leads to malfunctio n after a certain period. The substance mainly responsible for accumul ated calcium deposits in glutaraldehyde. The study was divided into wa s phases: chemical detoxification of the tissue by glutaraldehyde extr action to minimize calcification, and a subsequent PIXE analysis of mo re than 80 aortic wall samples to examine the efficiency of the detoxi fication process.
