Research Abstract

Although information about tissue stiffness is important for understanding its pathophysiology, noninvasive assessment of myocardial tissue stiffness was difficult. Recently, it has been reported that velocity of shear wave induced by acoustic radiation force impulse (ARFI) allows us to assess tissue stiffness. Therefore, we examined whether shear wave velocity could be evaluated in myocardium of open-chest dogs. In our results, shear wave velocity could be evaluated relatively accurately in limited myocardial regions.
