3. Heart valve of a pig by Jacob Brubert
This image is from research into novel prosthetic heart valves. Over 300,000 prosthetic heart valves are implanted worldwide each year, however current prosthetics only last up to 15 years or require lifelong anti-clotting therapy.
This image shows the heart valve of a pig, stained to highlight the collagen fibres. These fibres are integral to the durability of healthy native valves. This feature is used as inspiration for a new and improved polymer based prosthetic heart valve, ensuring broken hearts all over the world can get pumping again!
