Application of Echocardiography on Transgenic Mice with Cardiomyopathies

Abstract EN

Cardiomyopathies are common cardiac disorders that primarily affect cardiac muscle resulting in cardiac dysfunction and heart failure.

Transgenic mouse disease models have been developed to investigate the cellular mechanisms underlying heart failure and sudden cardiac death observed in cardiomyopathy cases and to explore the therapeutic outcomes in experimental animals in vivo.

Echocardiography is an essential diagnostic tool for accurate and noninvasive assessment of cardiac structure and function in experimental animals.

Our laboratory has been among the first to apply high-frequency research echocardiography on transgenic mice with cardiomyopathies.

In this work, we have summarized our and other studies on assessment of systolic and diastolic dysfunction using conventional echocardiography, pulsed Doppler, and tissue Doppler imaging in transgenic mice with various cardiomyopathies.

Estimation of embryonic mouse hearts has been performed as well using this high-resolution echocardiography.

Some technical considerations in mouse echocardiography have also been discussed.
