Sex-Related Factors in Valvular Heart Disease: JACC Focus Seminar 5/7.

Journal of the American College of Cardiology, 2022
Numerous sex-based differences are observed across the spectrum of valvular heart disease, starting with pathophysiology and progression of disease, moving on to compensation and comorbidities (both cardiovascular such as coronary artery disease and ...

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Systolic ejection murmurs and the left ventricular outflow tract in boxer dogs [PDF]

, 2007
Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low intensity.

The Risk of Acute Kidney Injury and Its Impact on 30-Day and Long-Term Mortality after Transcatheter Aortic Valve Implantation

International Journal of Nephrology, 2012
Background. Transcatheter aortic valve implantation (TAVI) is widely used in high risk patients (pts) with aortic stenosis. Underlying chronic kidney disease implicates a high risk of postprocedural acute kidney injury (AKI).

Fully Wireless and Flexible Valves for Multiplexed and Prolonged Intravesical Liquid Release

Advanced Healthcare Materials, EarlyView.
A fundamental mechanism for the simultaneous control of multiple magnetic valves is reported in a miniature soft robotic patch for intravesical drug delivery, enabling fully wireless and programmable liquid release. Integrated with a bioadhesive interface and induction‐coupling‐based liquid volume sensing, the soft robotic patch is promising to enable ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Rationale and Design of the CREATE Trial: A Multicenter, Randomized Comparison of Continuation or Cessation of Single Antithrombotic Therapy at 1 Year After Transcatheter Aortic Valve Replacement

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Current guidelines and expert consensus recommend lifelong single antiplatelet therapy for patients undergoing transcatheter aortic valve replacement who have no indication for anticoagulation or dual antiplatelet therapy. However, there is no
