Echocardiography has been playing a significant role in diagnosis and prognosis of cardiovascular diseases. Strain imaging directly measures the dynamic deformation of the tissue, and provides semi‐quantitative assessment of myocardial and vascular stiffness in terms of strain or strain rate. This chapter reviews the different cardiovascular shear wave imaging techniques. Three main shear wave generation methods have been developed for cardiovascular applications: external mechanical vibration, acoustic radiation force, and intrinsic physiological motion. Both the myocardial and vascular walls are viscoelastic tissues and show significant frequency‐dependent wave speed dispersion. Dispersion analysis provides comprehensive details of elasticity and viscosity of the tissue. The quantitative shear elasticity measurements obtained with ultrasound shear wave elastography offers great potential for many clinical applications. Myocardial contractility is conventionally measured invasively by catheterization. Carotid artery plaque characterization has been extensively investigated by non‐shear wave‐based techniques such as strain imaging and acoustic radiation force impulse imaging.
