A Pulsatile Bioreactor for Conditioning of Tissue-Engineered Cardiovascular Constructs under Endoscopic Visualization

Journal of Functional Biomaterials, 2012
Heart valve disease (HVD) is a globally increasing problem and accounts for thousands of deaths yearly. Currently end-stage HVD can only be treated by total valve replacement, however with major drawbacks.

A guide to the ecological limitations of phage therapy of bacterial biofilms: Is what's best for the phage best for the physician?

The FEBS Journal, EarlyView.
Bacteriophages—viruses that kill bacteria—are promising weapons against bacterial biofilms: sessile communities notoriously resistant to antibiotics. Yet phages evolved not so much to eradicate bacteria as to obtain new bacteria to infect. That goal, however, may conflict with the physician's objective of complete bacterial clearance.

Can Artificial Intelligence Be Utilised to Develop Point‐of‐Care Endodontic Microbiological Technologies?

International Endodontic Journal, EarlyView.
ABSTRACT Background Primary or persistent endodontic disease is caused by microbial biofilms that irritate the pulp and periapical tissues. Extensive microbiological analyses of these biofilms and their constituent pathogens have revealed their diversity and complexity.

Refining Residual Ischemic Stroke Risk in Anticoagulated Atrial Fibrillation Using Index Outpatient LA Diameter: The CHA2DS2‐VALa Score

Journal of Cardiovascular Electrophysiology, EarlyView.
In anticoagulated atrial fibrillation, residual ischemic stroke risk persists despite guideline‐directed therapy. In this single‐center cohort, an enlarged index outpatient left atrial diameter independently predicted stroke and improved risk stratification when added to CHA2DS2‐VA (CHA2DS2‐VALa), supporting a simple, clinically implementable ...

Frailty and Five‐Year Mortality After TAVR in Patients Aged 75 Years and Older

Journal of the American Geriatrics Society, EarlyView.
In patients aged 75 years and older undergoing transcatheter aortic valve replacement, frailty assessed by the Clinical Frailty Scale was the most robust geriatric factor independently associated with five‐year mortality. This study highlights the specific prognostic value of frailty beyond short‐term outcomes.

Hemodynamic comparison of polyurethane trileaflet and tissue heart valve prostheses

, 1988
In this paper, a hemodynamic comparison of two polyurethane trileaflet heart valve prostheses with currently available biological tissue valve prostheses are made. The valves, sutured to a valve mounting ring are incorporated in a mock circulatory system
