A Chronic Cardiac Ischemia Model in Swine Using an Ameroid Constrictor

Area of Science:

• Cardiovascular Research
• Animal Models
• Surgical Techniques

Background:

• Cardiovascular disease is a leading cause of death in the US.
• Pigs are a common large animal model for cardiovascular studies due to cardiac similarities with humans.
• In vivo models are essential for testing cardiovascular disease treatments.

Purpose of the Study:

• To provide a detailed overview of the ameroid placement technique.
• To highlight the advantages of using the ameroid constrictor for inducing myocardial infarction.
• To establish the ameroid constrictor as a preferred method for cardiovascular research.

Main Methods:

• Utilizing the ameroid placement technique to create an ischemic region in the heart.
• Employing pigs as the in vivo model for cardiovascular disease research.
• Detailing the surgical procedure for ameroid constrictor placement.

Main Results:

• The ameroid constrictor technique is a prevalent and effective method for inducing myocardial infarction in animal models.
• Advantages include availability in various sizes, a relatively simple surgical procedure, and minimal post-operative monitoring.
• This model supports research in surgical techniques, pharmaceuticals, imaging, and cell therapies.

Conclusions:

• The ameroid constrictor is a versatile and widely adopted technique for creating cardiac ischemia in large animal models.
• Its ease of use and minimal monitoring requirements make it ideal for diverse cardiovascular research applications.
• This paper details the proper placement technique for the ameroid constrictor, supporting its continued use in the field.
