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
The purse-string suture secures the cannula insertion site in the exposed ascending aorta. Its role is to help maintain control around the access point while blood is delivered from the bypass circuit. Effective securing and control can reduce bleeding and vessel injury, supporting safer arterial perfusion during cardiac surgery.
The cannula provides a route for oxygenated blood from the cardiopulmonary bypass circuit to enter the systemic circulation while the heart and lungs receive temporary support. This allows perfusion to continue during procedures that require cardiac arrest, helping maintain circulation while surgeons perform operations inside the heart.
Direct access to the ascending aorta can provide high-flow arterial perfusion to the systemic circulation. This is particularly relevant when the operation requires substantial circulatory support, such as valve repair, valve replacement, or cardiac arrest. Adequate placement and control remain important because perfusion must reach organs without causing vessel injury or air embolism.
The surgical team first exposes the ascending aorta and identifies the intended access site. A purse-string suture is then placed to secure that site, followed by insertion of the perfusion cannula. Once established, the cannula connects arterial flow from the bypass circuit with the systemic circulation, allowing support to begin.
This approach is used in open cardiac operations requiring arterial access for cardiopulmonary bypass. The provided examples include valve repair, valve replacement, and procedures in which the heart must be arrested. Its direct, high-flow perfusion makes it relevant when temporary support of circulation is needed during these interventions.
Safe use depends on accurate cannula placement and careful control of the access site and blood flow. The principal concerns identified for this technique are bleeding, vessel injury, air embolism, and inadequate organ perfusion. Managing these risks is important because each can compromise the effectiveness or safety of bypass-supported cardiac surgery.
