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 demonstrates intraduodenal cannulation in a rat model. After anesthetizing the rat, the duodenum is located and a small puncture is created. A J-shaped cannula with a beveled tip is carefully inserted and secured, and the incision is closed. The cannulated rat model enables intra-intestinal infusion for immunopathology studies.

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.

A protocol for the cannulation of the mouse submandibular salivary gland via the Wharton's duct is described. For this experiment, the trypan blue solution is used as a dyer to demonstrate how this technique effectively delivers infusions into the targeted gland, and to suggest the reliability of this new approach as a potential clinical drug/cell therapy for the regeneration of salivary glands.

FAQs
Site selection determines where arterial access is established and directly affects the ability to maintain systemic perfusion while limiting injury. The chosen aortic location must accommodate secure placement and connection to the bypass circuit. Careful selection is therefore important because inappropriate positioning can contribute to bleeding, dissection, air embolism, or cannula malposition during cardiac surgery.
A purse-string suture secures the cannula insertion site in the aortic wall. This controlled fixation helps maintain the cannula’s position and supports management of the entry site while blood is directed through the bypass circuit. Its role is especially relevant because inadequate control at the insertion point may increase the risk of bleeding or malposition.
Arterial pressure monitoring provides information about perfusion while the cannula and bypass circuit support the circulation. Observing pressure helps the surgical team assess whether systemic blood flow is being maintained during the procedure. It also supports early recognition of an unfavorable cannulation condition, making monitoring an important safeguard against inadequate perfusion or related complications.
Once the cannula connects the patient’s arterial circulation to the bypass circuit, the pump and oxygenator can deliver blood while the heart is stopped or its workload is reduced. This separation of circulatory support from normal cardiac pumping creates the conditions needed for open-heart operations. The technique therefore enables procedures requiring controlled cardiac function and systemic perfusion.
The process begins with selecting an appropriate aortic insertion site and placing a purse-string suture to secure it. The cannula is then inserted in a controlled manner and connected to the cardiopulmonary bypass circuit. Arterial pressure monitoring accompanies this sequence, helping maintain perfusion and identify problems such as bleeding, air embolism, dissection, or malposition.
Aortic cannulation supports open-heart procedures in which the heart must be stopped or its workload reduced while circulation continues through bypass. The overview identifies valve, aortic, and congenital heart operations as relevant applications. Its intended outcome is continued systemic perfusion during the operation, while careful technique limits complications that could compromise surgical support.
