Key result
A polyphenolic solution eliminated at least 99.9% of microorganism strains and inhibited S. aureus adhesiveness on bioprosthetic heart valve leaflets by 96% compared to untreated samples.
Why the study?
Infective endocarditis incidence in bioprosthetic heart valve patients is over 100 times that of the general population, with S. aureus causing approximately one-third of cases.
Does a polyphenolic solution reduce microbial viability and S. aureus adhesiveness in bioprosthetic heart valve models?
Population
9 microorganism strains, 3 viral strains, and leaflets from a commercial bioprosthetic heart valve model
Comparison
Polyphenolic solution treatment vs untreated samples
Design
In vitro experimental study

May warrant preclinical optimization of treated valves; leaves open whether endocarditis incidence declines in patients.
Does a polyphenolic solution reduce microbial viability and S. aureus adhesiveness in bioprosthetic heart valve models?
A polyphenolic solution demonstrates strong microbicidal activity and significantly reduces S. aureus adhesiveness on bioprosthetic heart valve leaflets in vitro.
Naso et al. (2022) studied Infective endocarditis (in vitro model). Polyphenolic solution vs. Untreated samples was evaluated on Inhibition of S. aureus adhesiveness. A polyphenolic solution eliminated at least 99.9% of microorganism strains and inhibited S. aureus adhesiveness on bioprosthetic heart valve leaflets by 96% compared to untreated samples.
