Abstract:
Objective To evaluate the two-dimensional strain by speckle tracking echocardiography in healthy piglets.Methods 9 small Guizhou-Panama pigs were used.High frame rate two-dimensional images were recorded from the left ventricular short-axis views at the levels of mitral annulus,papillary muscle and apex.Radial strain,circumferential strain and rotation were measured in the left ventricular short-axis views using two-dimensional strain software.Results Left ventricular two-dimensional radial strain gradually increased from the base to apex.As seenfromthe apex.LV performs a wringing motion with a clockwise rotation at the base and counterclockwise rotation at the apex.Conclusion 2DS technique is a rapid,accurate,easy,repeatable and no angle reliant method to quantitatively estimate the left ventrlcle function.
