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.

This video describes the technique for performing angiography by injecting a contrast agent into the descending aorta to visualize blood vessel perfusion in a rabbit model. This technique helps to understand the perfusion in blood vessels with blockages and after treatment during recovery.

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.
FAQs
Timing coordinates the intravenous iodinated contrast injection with CT image acquisition, so the scan captures increased X-ray attenuation within the blood. This makes the aorta and its major branches stand out from surrounding tissues. Appropriate timing is especially important when clinicians need a rapid, detailed view of suspected vascular abnormalities or potentially life-threatening aortic disease.
Cross-sectional images show the aorta slice by slice, while software-generated three-dimensional reconstructions provide a broader view of vessel anatomy and abnormal regions. Together, these representations help clinicians examine the extent and location of disease with high spatial resolution. The combined information can support assessment of complex vascular findings and contribute to treatment planning.
Aortic CT angiography can help evaluate aneurysms, dissections, stenosis, traumatic injury, and other aortic abnormalities. These conditions affect the vessel in different ways, so visualizing the aorta and its major branches is important for identifying the relevant vascular pattern. The resulting images support rapid clinical assessment when a serious aortic condition is suspected.
During the examination, iodinated contrast material is injected into a vein, followed by timed CT scanning. The scanner records X-ray attenuation as the contrast-enhanced blood passes through the aorta, and software reconstructs the results into cross-sectional and three-dimensional images. This workflow produces detailed vascular information without surgical access to the aorta.
Clinicians may choose Aortic CT angiography when they need a rapid evaluation of suspected vascular disease, particularly in potentially life-threatening aortic conditions. Its speed and high spatial resolution make it useful for examining the aorta and major branches in situations involving aneurysm, dissection, stenosis, traumatic injury, or another abnormality requiring prompt characterization.
The reconstructed images show the location and extent of abnormalities in the aorta and its major branches, giving clinicians information for treatment planning. The same imaging approach can also be used during follow-up to reassess known vascular disease over time. This makes it relevant both to initial evaluation and to continued medical management of aortic conditions.
