Percutaneous aortic valve replacement safe, successful in high-risk patients

...urvivors showed that the average aortic valve area more than doubled, on average, following the procedure. In addition, the severity of heart failure significantly improved, as gauged by both B-type natriuretic peptide (NT-BNP), a protein produced by the ventricles of the heart during heart failure, and N...

Tissue engineered scaffolding allows reproduction of cartilage tissue

...ice as the study found these scaffolds to be a far more effective means of regenerating cartilage than traditional therapy. The shrinkage of cartilage that occurs frequently in other tissue engineering methods, and often renders the replacement tissue wrongly-sized for implantation, did not occur in the s...
