Tissue Doppler characterization of cardiac phenotype in mouse

Mice allow biologists to study various genes playing a role in cardiac function and pathophysiological situations. Echocardiography is a non-invasive tool for assessing cardiac phenotype. Because of load dependence of conventional parameters (left ventricular shortening fraction, left ventricular ejection fraction and mitral pulsed Doppler), we have to perform Doppler tissular velocity imaging and strain imaging for the characterization of cardiomyopathies mice models.
