Mariam Abdi Noor

During her PhD studies, Mariam Abdi Noor has developed and evaluated a novel implant for the aortic valve – which is one of four valves in the human heart. The implant is a supportive ring with the aim of supporting the aortic valve due to an ineffective closure of the valve during the cardiac cycle. Generally, for patients who have a diseased aortic valve, the preferred procedure has most cases been to replace the valve with an artificial valve. However, this can cause several complications and is not always feasible.

Mariam Abdi Noor has in this study aimed to develop the support ring aortic ring as well as investigate the functionality and effect of the ring in a heart simulator as well as in live pigs.

The invention has resulted in a patent application
