All animal handling procedures were conducted in compliance with the NIH Care and Use of Laboratory Animals guidelines and approved by the Animal Studies Committee at Washington University School of Medicine. Hearts from C57BL/6 (B6) and BALB/c mice (weighing 20-25 g) were transplanted into gender-matched B6 recipients (6-8 weeks of age). The mice were obtained from commercial sources (see Table of Materials). Syngeneic transplants were performed to evaluate cellular responses related to ischemia-reperfu...

Utilizing this technique, mouse heterotopic cervical cardiac transplantation can be performed in less than 40 min by an experienced microsurgeon and in approximately 60 min by an entry-level microsurgeon. While cervical heart transplantation has been studied in numerous animal models, a mouse model remains the gold standard due to multiple well-defined genetic strains, genetic alteration capabilities, and the availability of numerous reagents, including monoclonal antibodies24. The technique descr...

Abbott et al. published1 the first description of heterotopic abdominal heart transplantation in rats in 1964. These surgical techniques were refined and simplified by Ono et al. in 19692. Corry et al. first described a method for heterotopic abdominal heart transplantation in mice in 1973; similar to the previously reported rat models, this involved engraftment into the host&#39;s abdomen with revascularization by end-to-side anastomoses of the donor&#39;s pulmonary artery and ascending aorta to the recipient&#39;s inferior vena cava and abdominal aorta, respectively3. Heterotopic cervical heart transplantation in rats was described by Heron in 1971 using Teflon cuffs made from 16 G (1.6 mm outer diameter) intravenous catheters4. Chen5 and Matsuura et al.6 later reported heterotopic cervical heart transplantation in mice in 1991, whose techniques differed primarily in their method of re-anastomosis. Chen&#39;s approach involved sutured anastomoses of the donor&#39;s ascending aorta to the carotid artery of the recipient and the donor&#39;s pulmonary artery to the external jugular vein of the recipient5. Due to the advanced technical skill required for these microsurgical sutured anastomoses, a significant amount of time and experience was necessary to achieve a high success rate. Matsuura et al. described a method utilizing a non-suture cuff technique, similar to that used by Heron, which involved end-to-end anastomoses using the extra-luminal placement of cuffs. He fashioned Teflon cuffs from 22 G (0.8 mm outer diameter) and 24 G (0.67 mm outer diameter) intravenous catheters and placed them over the recipient&#39;s external jugular vein and common carotid artery, respectively6. These cuffs were then placed inside the donor&#39;s pulmonary artery and aorta and secured by tying a suture ligature around the connection. This approach translated into an improved success rate. Most importantly, it resulted in a shortening of the time required to complete both cervical anastomoses, thus reducing the warm ischemic time of the graft to less than one-third of that utilizing the abdominal suturing method. Furthermore, since the cuffs are placed around the external surface of the vessel, there is no foreign body exposed to the vessel lumen, which largely reduces the possibility of thrombosis after surgery7. Meanwhile, utilization of the cuff technique provides support around the vessels at the site of the anastomosis without requiring any suturing, which reduces the risk of bleeding after revascularization6.
Numerous revisions of this technique have been proposed. To accommodate the short length of the mouse common carotid artery (approximately 5 mm), Tomita et al.8 developed a modification of this technique with a smaller arterial cuff (0.6 mm outer diameter) while omitting holding sutures and pulling the artery directly through the cuff with fine forceps instead. Wang et al. further simplified this approach by placing 22 G and 24 G cuffs on the donor&#39;s right pulmonary artery and recipient&#39;s right common carotid artery, respectively9. Various reports have described modifications to these approaches, including the use of specialized cuffs, microsurgical clamps, vessel dilators, and cardioplegia10,11,12. Notably, all of these methods involve the retrograde circulation of blood through the heart, with blood flowing from the recipient common carotid artery to the donor aorta, the coronary arteries, the coronary sinus, then emptying into the right atrium and exiting from the pulmonary artery into the recipient external jugular vein.
Compared to engraftment in the abdomen, cervical cardiac transplantation offers multiple advantages. As previously mentioned, cervical exposure allows for quicker revascularization and shorter warm ischemic times6. The cervical method is also less invasive and is associated with shorter postoperative recovery times as it avoids a laparotomy6. Importantly, end-to-end anastomoses with cuffs can be performed instead of end-to-side anastomoses, which decreases the risk of complications such as anastomotic bleeding. The abdominal approach also poses an increased risk of developing thrombotic complications in the abdominal aorta or inferior vena cava, leading to spinal cord ischemia and hindlimb paralysis. The superficial cervical location of the transplant allows for easy access to graft viability assessment by palpation, electrocardiography, and invasive or non-invasive imaging. Although the cervical grafts resume spontaneous cardiac activity following reperfusion, they do not significantly impact the systolic and diastolic parameters of the recipient. This model provides valuable insight for studying cellular responses following transplantation, such as ischemia-reperfusion injury and graft rejection. Furthermore, this model offers an ideal approach to allow for post-transplant imaging, such as intravital two-photon microscopy or positron emission tomography (PET) imaging. To this end, our laboratory has previously reported methods to image moving tissues and organs in the mouse, including beating murine hearts and aortic arch grafts following heterotopic cervical transplantation&#160;to visualize leukocyte trafficking during ischemia-reperfusion injury and within atherosclerotic plaques, respectively13,14,15. Additionally, due to its superficial location and ease of exposure, this model is suitable for cardiac re-transplantation16.
This report describes a technique that allows for laminar blood flow with the external placement of the vascular cuffs on the vessels from which blood flow originates. This allows for a smooth transition of blood flow from one vessel to the next, avoiding the exposure of the distal vessel edge into the vascular lumen. Additionally, the technique utilizes a larger 20 G cuff, instead of previously used 22 G cuffs, for the donor pulmonary artery to ensure ample return of blood flow to the recipient.

mouse heterotopic cervical cardiac transplantation utilizing vascular cuffs

Murine models of cardiac transplantation are frequently utilized to study ischemia-reperfusion injury, innate and adaptive immune responses after transplantation, and the impact of immunomodulatory therapies on graft rejection. Heterotopic cervical heart transplantation in mice was first described in 1991 using sutured anastomoses and subsequently modified to include cuff techniques. This modification allowed for improved success rates, and since then, there have been multiple reports that have proposed further technical improvements. However, translation into more widespread utilization remains limited due to the technical difficulty associated with graft anastomoses, which requires precision to achieve adequate length and caliber of the cuffs to avoid vascular anastomotic twisting or excessive tension, which can result in damage to the graft. The present protocol describes a modified technique for performing heterotopic cervical cardiac transplantation in mice which involves cuff placement on the recipient's common carotid artery and the donor's pulmonary artery in alignment with the direction of the blood flow.

This mouse cervical heterotopic cardiac transplantation model has been utilized to perform over 1,000 transplants in our laboratory, with a survival rate of approximately 97%. The success rate is slightly higher than previous reports using other cervical heterotopic heart transplantation techniques in mice10,11,20. This could potentially be attributed to the larger 20 G cuff placed on the donor pulmonary artery to ensure ample r...
