GONZALEZ DIAZ, Ida et al. Echocardiographic assessment of the myocardial fiber deformation in patients presenting with stable angina with and without coronary lesions. Rev Cubana Invest Bioméd [online]. 2010, vol.29, n.2, pp.203-212. ISSN 0864-0300.

Echocardiographic images of tissue Doppler and its derivatives (deformation and regional deformation velocity) allowed us to visualize the behavior of myocardial fibers quantifying the segmental and global cardiac function. To determine the deformation and deformation velocity values of the myocardial fiber with a high level of specificity and sensitivity in the diagnosis of significant coronary lesions in patients presenting with stable angina. The section points by segments showed a high sensitivity and specificity in detection of coronary lesions for the parameters of deformation and systolic deformation velocity in basal segments (septal, lateral and anterior) with sensitivity values of 80%, 87% and 93% and specificity values of 80, 87% and 73%, respectively.
