Deformation of the Left Ventricular Myocardium in Patients with Ischemic Heart Disease Before and after Revascularization when Using Velocity Vector Imaging
Abstract
The aim: to assess the impact CHD and surgical revascularization on parameters of strain (S) and strain rate (SR) longitudinal, circular and radial fibers of the LV.
Materials and methods. In 450 segments LV deformation (S and SR) longitudinal, circular and radial fibers was analyzed before and after surgical revascularization.
Results. The study of averages S and SR showed the low S longitudinal fibers, low S and SR circular fibers and normal S and high SR radial fibers, no changes in these parameters after revascularization. A detailanalysis the segments showed a decrease S and SR in 211 (46.8%) segments of longitudinal, 232 (51.5%) circular and 116 (25.7%) of the radial fibers of the LV. The same 239 (53.2%) segments of longitudinal, 218 (48.5%) and circular 328 (72.8%) segments of the radial fibers had normal and increased values of S and SR as well as with different options to change S or SR. After revascularization improved deformation properties of longitudinal and circular fibers of the left ventricle in the group with low values of S and SR. The increased number of segments with high or normal value of SR. Normal values of S and SR radial fibers observed in most segments (254 (56.7%).
Conclusion. Technology Velocity Vector Imaging to conduct a detailed analysis of LV segments and to estimate the dynamics of the deformation properties of longitudinal, circular and radial fibers after revascularization.
