돼지 대동맥 협착증의 최소 침습 모델

Overview

This protocol describes a minimally invasive surgical procedure for ascending aortic banding in swine. It aims to provide a reliable and reproducible model for studying cardiac pathologies.

Key Study Components

Area of Science

• Cardiovascular research
• Surgical models
• Large animal studies

Background

• Preclinical cardiovascular research often uses small animal models.
• Small models have limitations in translating findings to humans.
• Large animal models can better mimic human pathophysiology.
• This protocol focuses on a minimally invasive approach to enhance animal welfare.

Purpose of Study

• To develop a reliable model for studying cardiac conditions.
• To ensure reproducibility in experimental results.
• To balance surgical intervention with animal welfare considerations.

Methods Used

• Minimally invasive surgical procedure for ascending aortic banding.
• Use of high-fidelity pressure sensors for real-time monitoring.
• Accurate titration of pressure gradients across the stenosis.
• Comparison of severity of conditions between different animals.

Main Results

• Successful implementation of the surgical procedure.
• Consistent pressure gradients achieved across subjects.
• Demonstrated reliability and reproducibility of the model.
• Enhanced understanding of cardiac pathologies in a large animal context.

Conclusions

• The protocol provides a valuable tool for cardiovascular research.
• It addresses the limitations of small animal models.
• Promotes better translation of research findings to clinical settings.
