What is a heterotopic heart transplant?
Heterotopic heart transplantation (HHT) is a surgical procedure that allows the graft to be connected to the native heart in a parallel fashion. The main advantage of HHT is to assist the patient’s native heart and to maintain circulation in the cases of severe acute rejection.
What does orthotopic transplantation mean?
Orthotopic transplantation refers to the delivery of cancer cells to the anatomic location or tissue from which a tumor was derived (Khanna and Hunter, 2005).
What is Bicaval heart transplant?
A bicaval approach preserves the donor atria and combines the standard left atrial anastomosis with a separate bicaval anastomosis. Total orthotopic heart transplantation involves complete excision of the recipient atria with separate bicaval end-to-end anastomoses, as well as pulmonary venous anastomoses.
What is the heterotopic?
Heterotopic: In the wrong place, in an abnormal place, misplaced. From the Greek roots “hetero-” meaning “other” + “topos” meaning “place” = other place. For example, heterotopic bone formation is the formation of bone where it is not normally found, as in muscle.
What is piggyback heart?
Surgeons last month performed a heterotopic, or piggyback, heart transplant that involves connecting a donor’s heart to the patient’s heart, as shown in the diagram above. This was the first time the procedure was performed on a child in California.
How does a piggyback heart transplant work?
Heterotopic transplantation, also called “piggyback” transplantation, is accomplished by leaving the recipient’s heart in place and connecting the donor heart to the right side of the chest.
What’s a piggyback transplant?
What is Bicaval technique?
The bicaval technique offers better preservation of right atrial morphology and function than the biatrial technique, with the maintenance of the physiological atrial pacing pathway. Additionally, it allows the preservation of sinus rhythm, reducing the incidence of supraventricular arrhythmias [11] .
What is a piggyback heart transplant?
What is heterotopic bone formation?
Heterotopic ossification is abnormal bone formation within muscle and soft tissues, an unfortunately common phenomenon that typically occurs weeks after an injury or surgery. Patients with heterotopic ossification experience decreased range of motion, swelling and pain.

Can mice be used as donors and recipients for heart transplants?
Mice are often used as heart transplant donors and recipients in studies of transplant immunology due to the wide range of transgenic mice and reagents available. A difficulty is presented due to the small size of the animal and the considerable technical challenges of the microsurgery involved in heart transplantation.
Can mice be used as a model for mechanical unloading?
Heterotopic heart transplantion (hHTX) is an accepted model for the study of mechanical unloading in rodents. The wide variety of genetically modified strains in mice provides an unique opportunity to examine remodeling pathways. However, the procedure is technically demanding and has not been extensively used in this area.
