Similar to testing a car, a team of researchers at UBC Okanagan has been test-driving a number of mechanical heart valves (MHV)—and the one designed in their own lab appears to outperform the others.

Dr. Mohammadi also says while mechanical heart valve replacements have long been in use, the long-standing challenge has been to perfect the technology for the smallest hearts -- tiny infants.
