Valves Four cardiac valves Two categories One way blood flow Based on location in heart Atrioventricular Valves Mitral and Tricuspid Semilunar valves Aortic and Pulmonic Atrioventricular valves Located between Atria and Ventricles Diastolic valves-open during diastole Right Side Tricuspid valve Largest of c...
Endothelial cells were selectively labeled with an acetylated low-density lipoprotein marker and separated from the fibroblasts using a fluorescent activated cell sorter. A synthetic biodegradable scaffold constructed from polyglycolic acid fibers was seeded with fibroblasts, which grew to form a tissue-...
Five decellularized valves were conjugated with fluorescein isothiocyanate–labeled CD133 and placed in phosphate-buffered saline solution (with daily buffer changes) for 5 days. Daily, 1 valve was removed and examined for the presence of green fluorescence, indicating the continued presence of the ...

Current heart valve prostheses have limitations that include durability, inability to grow in pediatric patients, and lifelong anticoagulation. Transcatheter aortic valve replacements are minimally invasive procedures, and therefore have emerged as an alternative to traditional valve prostheses. In this experim...
Platelet survival time (PST) studies are useful to demonstrate whether or not patients with prosthetic heart valves have normal or shortened PST. During treatment for recurrent TIAs the PST will signal whether the patient is returning towards a normal PST. Using Indium-111 labeled platelets (ILP)...
(Tompkins RG, Schnitzer JJ, Yarmush ML. Circ Res 64: 1213-1223, 1989) found large variations in shape and magnitude in transvalvular 125I-labeled low-density lipoprotein (LDL) profiles from identical experiments on four squirrel monkeys. Their one- dimensional, uniform-medium diffusion-only ...
Alexa Fluor 488-labeled donkey anti-rabbit IgG antibody and Alexa Fluor 488-labeled donkey anti-sheep IgG antibody were from Life Technologies (USA). Allophycocyanin-conjugated anti-mouse IgG secondary anti- body (GP Ib, beta1), allophycocyanin-conjugated anti-mouse IgM (IIb/IIIa) and ...
labeled cine 2D and 4D flow MRI datasets to accelerate flow and diameter measurements in the aorta. However, the scarcity of high-quality labeled training datasets22effectively hampers the implementation of DL based inference approaches for 4D flow MRI. Fries et al.20alleviated the burden of ...
Anti-MNFG and anti-MYLK monoclonal antibodies, and horseradish peroxidase–labeled secondary antibodies were used. Immunofluorescence Acetone-fixed cryosections from four BAV and TAV non-dilated aorta were incubated with rabbit anti-VE-cadherin at 4 °C overnight, followed by AlexaFluor 594-labeled...
