Full-root aortic valve replacement by stentless aortic xenograft is a viable option in patients with small aortic roots. We describe, a technique for the full-root implantation of stentless aortic xenografts, with emphasis on the management of the proximal suture line and coronary anastomoses, and discuss its limitations and alternative options.

Angiogenesis, the sprouting of blood vessels from pre-existing vasculature, is associated with both natural and pathological processes. Here we demonstrate an aortic ring assay that allows angiogenic potentiators and inhibitors to be directly added to aortic rings in culture. Sprouting and neovessel outgrowth can be determined by inspecting the aortic rings over a period of 6-12 days.

Histological and biochemical modifications after aneurysm endograft exclusion are still unclear. We describe a new model of endograft implantation on a murine aneurysm. Through thrombus analysis with and without persistant circulating blood stream interface, and new endovascular biomaterials evaluation, this model will help to better understand endovascular aneurysm exclusion pathobiology.

Source: Shreyas Narsipur, Mechanical and Aerospace Engineering, North Carolina State University, Raleigh, NC A propeller is a twisted airfoil, where the angle of the chord changes with respect to the location, along the radial station, as shown in Figure 1. Propellers are widely used in aircraft and watercraft propulsion systems thereby necessitating detailed characterizations of propellers to design high performance vehicles. Figure 1. Chord, thickness, and pitch at a radial station. One of...
FAQs
A measurement has meaning only when clinicians know which anatomical segment was assessed and consider factors such as age and body size. These variables help place the observed width in an appropriate clinical context rather than treating every value as directly comparable. This interpretation supports more accurate assessment of vascular health and possible aortic disease.
Enlargement may reflect weakening of the aortic wall and can indicate an aneurysm. The clinical concern is not limited to the size recorded at one examination; changes over time may signal progression. Increasing diameter can therefore contribute to risk assessment for serious complications, including rupture or dissection, and help guide decisions about monitoring and care.
Serial measurements show whether the aorta remains stable or is changing across follow-up examinations. A change in diameter can indicate progression of underlying aortic disease and may increase concern about rupture or dissection. Tracking the pattern over time therefore provides information that a single measurement cannot, particularly for patients with suspected or known disease.
Clinicians can assess aortic diameter with echocardiography, ultrasound, computed tomography, or magnetic resonance imaging. The selected imaging approach provides measurements at specified aortic segments, which can then be interpreted alongside patient factors and clinical context. Using these modalities supports diagnosis, risk assessment, treatment planning, and follow-up when aortic disease is suspected or established.
The process begins by selecting an appropriate imaging examination and identifying the anatomical aortic segment to assess. Clinicians then obtain the diameter measurement, interpret it in relation to age and body size, and compare it with prior examinations when available. This sequence helps determine whether findings suggest enlargement, progression, or a need for continued evaluation.
Repeated measurements are particularly useful for patients with suspected or known aortic disease. Comparing examinations can reveal whether an enlargement is stable or changing, which informs risk assessment and follow-up. Serial assessment also supports treatment planning by giving clinicians a record of disease behavior rather than relying on an isolated measurement.
Aortic diameter measurements contribute to several stages of care, including screening, diagnosis, risk assessment, treatment planning, and follow-up. The result is interpreted with the measurement location and patient characteristics, while changes over time add evidence about progression. In this way, imaging findings help clinicians evaluate vascular health and monitor possible aneurysmal disease.
