Murine Echocardiography of Left Atrium, Aorta, and Pulmonary Artery

Overview

This protocol outlines the methodology for acquiring and analyzing echocardiographic images to determine left atrial volume and diameters of the aorta and pulmonary artery in mice. It is a non-invasive, non-terminal technique that enables assessment of cardiopulmonary function.

Key Study Components

Area of Science

• Cardiopulmonary function assessment
• Echocardiography
• Mouse models

Background

• The technique allows differentiation between pulmonary artery resistance and diameter changes.
• It enables serial assessments of the same animal.
• Proper probe and mouse positioning are critical for optimal image acquisition.
• This method can enhance monitoring of interventions in cardiopulmonary studies.

Purpose of Study

• To acquire echocardiographic images for measuring left atrial volume and arterial diameters.
• To provide a non-terminal approach for repeated assessments.
• To facilitate further research in cardiopulmonary science.

Methods Used

• Use of echocardiographic imaging systems.
• Selection of cardiac measurements from the system menu.
• Image acquisition following proper positioning protocols.
• Analysis of echocardiographic data to determine volume and diameter metrics.

Main Results

• Successful acquisition of echocardiographic images.
• Determination of left atrial volume and arterial diameters.
• Ability to distinguish between different cardiopulmonary conditions.
• Establishment of a reliable non-invasive assessment technique.

Conclusions

• The protocol provides a valuable tool for cardiopulmonary research.
