简介：
Overview
This protocol describes a large animal model of donation after circulatory death followed by thoracoabdominal normothermic regional perfusion that closely mimics clinical heart transplantation. This model has the potential to facilitate therapeutic studies and strategies in translational research.
Key Study Components
Area of Science
- Cardiac transplantation
- Translational research
- Large animal models
Background
- The model uses porcine subjects, which share anatomical and surgical similarities with human hearts.
- It aims to improve preclinical evaluation of cardiac transplantation techniques.
- Normothermic regional perfusion is a critical component of the protocol.
- This approach may enhance the understanding of heart transplantation outcomes.
Purpose of Study
- To develop a suitable preclinical model for cardiac transplantation.
- To evaluate potential strategies in translational research.
- To simulate clinical scenarios in heart transplantation.
Methods Used
- Midline incision on an anesthetized porcine model.
- Layer-by-layer division of subcutaneous fat using electrocautery.
- Retraction and sweeping of soft tissues from under the sternum.
- Implementation of thoracoabdominal normothermic regional perfusion.
Main Results
- The protocol successfully mimics clinical heart transplantation.
- It provides a robust framework for evaluating cardiac transplantation techniques.
- Demonstrates the feasibility of using large animal models in research.
- Facilitates the study of therapeutic strategies in cardiac care.
Conclusions
- This model is advantageous for preclinical cardiac transplantation studies.
- It bridges the gap between experimental research and clinical application.
- Further studies could enhance understanding of heart transplantation outcomes.
What is the main advantage of this protocol?
The main advantage is that it provides a suitable preclinical model for cardiac transplantation, closely mimicking human anatomy and surgical techniques.
How does this model facilitate research?
It allows for the evaluation of potential strategies in translational research related to heart transplantation.
What animal is used in this protocol?
The protocol uses a porcine model, specifically boar swine, due to their anatomical similarities to humans.
What surgical technique is employed?
A midline incision is performed, followed by electrocautery to divide subcutaneous fat and access the thoracic cavity.
What is normothermic regional perfusion?
It is a technique used to maintain organ viability during transplantation by providing warm blood flow to the heart.
Can this model be used for other types of research?
While primarily focused on cardiac transplantation, the model may have applications in other areas of translational research.
