- W2378639300 abstract "Objective To evaluate the value of speckle tracking echocardiography for assessing right ventricular function in heart transplant recipients.Methods Nine heart transplant recipients underwent 55 echocardiographic studies after heart transplantation.High frame rate two-dimensional images were recorded from apical four-chamber view.Peak systolic strain,strain rate,velocity,displacement and peak strain rate and velocity in early diastole and during atrial contraction of right ventricular free wall were measured using speckle tracking echocardiography.Fifty-four healthy individuals were measured as controls.Results Peak systolic strain,strain rate,velocity,displacement and peak strain rate and velocity in early diastole and during atrial contraction of all segments in right ventricular free wall reduced significantly in transplant recipients with and without acute rejection when compared with the controls(P0.05).Although the peak systolic strain,strain rate,velocity,displacement of segments in right ventricular free wall in transplant recipients with acute rejection showed the tendency to decrease when compared with transplant recipients without rejection,only the peak systolic displacement of middle and apical segment decreased significantly(P0.05).However,the peak strain rate and velocity in early diastole of all segments and the peak velocity during atrial contraction of apical segment in transplant recipients with acute rejection showed significant difference when compared with transplant recipients without rejection(P0.05).Conclusion Speckle tracking echocardiography can precisely quantify right ventricular function noninvasively in heart transplant recipients and provide some value in rejection diagnosis." @default.
