Polyurethane catheter insertion into the aortic lumen and suture ligation of the aorta induce chronic hypoxia due to hypoperfusion of the adventitial vasa vasorum. This article describes a novel animal model of abdominal aortic aneurysm (AAA) with characteristics similar to those of AAA in humans.

Langendorff Retrograde Heart Perfusion: An Ex Vivo Technique to Perfuse Isolated Mouse Heart

2025
In this video, we perform Langendorff retrograde perfusion of an isolated mouse heart. During the procedure, the cardiac activity of the heart is maintained by perfusing it retrogradely with a perfusion solution via the coronary arteries using a cannula inserted into the ascending aorta. The model is used to study the cardiac pathophysiology of the heart.

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 an antegrade perfusion technique of an isolated mouse heart during which a perfusate is injected through the left ventricle, and eventually, it perfuses the entire myocardium. This method can be used to isolate cardiomyocytes from murine models and generate decellularized hearts for further downstream applications.

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
Aortic perfusion is sustained by the interaction of ventricular ejection and aortic wall behavior. Systolic contraction initiates forward flow, then elastic expansion and recoil help preserve movement when the ventricle is not actively ejecting. This relationship explains why blood flow can remain continuous rather than occurring only as discrete heartbeats.
Vascular resistance determines how readily blood moves from the aorta into systemic tissues, while blood pressure provides the driving force for that movement. Changes in either factor can alter tissue delivery even when the heart continues to pump. For this reason, perfusion assessment considers circulation as a coordinated cardiovascular process, not an isolated vessel.
Delivery through the aorta links cardiac activity to oxygen availability in organs. If circulation is inadequate, tissues may not receive the blood flow needed to support normal function; preserved delivery provides evidence that systemic circulation is supporting organ needs. This connection makes perfusion a useful physiological indicator in biology and medicine.
These conditions represent distinct settings in which circulation may require evaluation. Hypertension concerns blood pressure, atherosclerosis concerns the state of the arterial system, and shock concerns the preservation of circulation under severe physiological stress. Studying aortic perfusion across these contexts helps relate cardiovascular changes to systemic blood delivery and organ oxygenation.
Assessment can provide information about cardiovascular function, organ oxygenation, and the adequacy of systemic circulation. Its value comes from connecting blood movement through the major arterial pathway with effects on tissues. Consequently, it can help investigators or clinicians characterize whether circulation is being maintained under normal conditions or during disease-related changes.
Preserving aortic perfusion matters during surgery or critical care because systemic tissues depend on continued blood delivery from the heart through the aorta. Monitoring this circulation can support efforts to maintain cardiovascular function and organ oxygenation when the body is under stress. The same principle also guides research into strategies for protecting blood flow.
