Using the Canadian Light Source (CLS) at the University of Saskatchewan, Marta Cerruti, an Associate Professor in McGill’s Department of Materials Engineering, and her team analyzed damaged heart valves from patients who had undergone transplants. Their findings, recently published in Acta Biomaterialia, show considerable differences in the mineral deposits found in aortic valves of men...
