Echocardiography-Guided Intramyocardial Injection Method in a Murine Model

Area of Science:

• Cardiovascular Research
• Regenerative Medicine
• Animal Models

Background:

• Cardiac regenerative therapy aims to treat heart damage.
• The mouse model of myocardial infarction (MI) is crucial for evaluating these therapies.
• Traditional intramyocardial delivery in mice requires invasive open-chest surgery.

Purpose of the Study:

• To describe a minimally invasive method for intramyocardial injection in a mouse MI model.
• To present echocardiography-guided transthoracic myocardial injection as an alternative to open-chest surgery.
• To highlight the benefits of reduced complications and faster recovery.

Main Methods:

• Utilizing echocardiography for precise guidance.
• Performing transthoracic myocardial injection for therapeutic delivery.
• Employing a mouse model of myocardial infarction (MI).

Main Results:

• Echocardiography-guided injection allows reliable delivery of therapeutics to the target site.
• This minimally invasive approach results in fewer complications.
• Animals exhibit quicker recovery post-procedure compared to open-chest surgery.

Conclusions:

• Echocardiography-guided intramyocardial injection is a viable and less invasive method for cardiac regenerative therapy research in mice.
• This technique facilitates efficient evaluation of novel treatments for myocardial infarction.
• The method supports improved animal welfare and experimental efficiency.
