Innovative Strategies for Organ Preservation in Heart Transplantation: Uniform Cooling Preservation and Ex-situ Normothermic Perfusion
0 Views •
2025
Donor heart preservation is a major determinant of success in heart transplantation. Technological advances have led to optimizing the conditions of preservation, along with a more accurate assessment of the donor heart before transplantation. We herein describe two innovative technologies currently applied for cardiac preservation: uniform cooling preservation and normothermic ex-situ heart perfusion.

Source: Sanchez, C. A., et al. Preparation of Peripheral Nerve Stimulation Electrodes for Chronic Implantation in Rats. J. Vis. Exp. (2020).This video demonstrates vagus nerve stimulation in an awake rat. A rat with an implanted chronic peripheral nerve cuff electrode and trained in a lever press task is connected to a stimulus generator via an implanted head cap. The vagus nerve is stimulated immediately after each successful lever press, resulting in the expansion of the motor map.

Calcium is a ubiquitous messenger in the nervous system, essential for triggering neurotransmitter release and changes in synaptic strength. Here we demonstrate a technique for loading Ca2+-indicators into Drosophila nerve terminals. We also demonstrate fabrication of the required apparatus and emphasize points critical for the technique's success.

Source: Li, Q., et al. Investigating Mammalian Axon Regeneration: In Vivo Electroporation of Adult Mouse Dorsal Root Ganglion. J. Vis. Exp. (2018)This video demonstrates the process of axonal regeneration in a mouse sciatic nerve following a crush injury. The isolated nerve is fixed and prepared for imaging, with fluorescent proteins expressed in neurons to visualize axon growth. Using an epifluorescence microscope, axon regeneration is traced from the injury site to assess the extent of...
FAQs
Protecting a nerve’s blood supply matters because preservation is not limited to avoiding direct contact. Clinicians also separate the nerve from nearby tissues while maintaining its circulation. This anatomical approach is especially important when a nerve lies close to the operative area, because treatment must proceed without unnecessarily compromising the pathway’s ability to function after surgery.
Electrical stimulation paired with electromyography provides real-time functional monitoring during an intervention. Stimulation can assess whether a pathway responds, while electromyography helps track functional activity. This complements visual identification of anatomy: a structure may be located and separated surgically, yet monitoring can provide additional information about whether important functional pathways remain active during the procedure.
Nerve preservation requires clinicians to address the medical or surgical problem while limiting avoidable harm to nearby neural pathways. The goal is therefore not simply to leave tissue untouched, but to plan treatment around anatomy, blood supply, and functional monitoring. This balance can support recovery while reducing the risk of weakness, numbness, pain, or impaired organ function.
A typical strategy combines anatomical identification, careful separation from adjacent tissues, protection of the nerve’s blood supply, and functional assessment when electrical stimulation with electromyography is available. These elements work together rather than serving as isolated precautions. Used during operative planning and the procedure itself, they help clinicians preserve relevant pathways while continuing the intended intervention.
Nerve preservation is relevant wherever treatment occurs near important neural structures. The overview identifies neurosurgery, orthopedics, otolaryngology, and oncology as key fields. In each setting, the approach helps clinicians incorporate nerve location and function into operative planning, allowing them to pursue effective treatment while considering possible long-term effects on movement, sensation, pain, or organ function.
The intended outcomes include maintaining neurological function and supporting recovery and quality of life after an intervention. Preservation strategies may reduce postoperative weakness, numbness, and pain, while also lowering the likelihood of losing organ function when relevant pathways are involved. These outcomes make nerve status an important part of evaluating treatment beyond the immediate technical success of surgery.
