Abstract: Aim: was to assess dynamics of strain (S) and strain rate (SR) of longitudinal, circular and radial fibers in patients with left ventricular (LV) aneurysm (LVA) before and in early stages after coronary artery bypass graft (CABG) using Velocity Vector Imaging. Material and methods: in 270 segments LV in patients with LVA, S and SR of LV fibers was analyzed before and after CAB. Also analysis of S and SR was performed in patients with CABG and plastic of the LV (group 1, 144 segments) and in the group with CABG without plastic of the LV (group 2, 126 segments). Results: a function of longitudinal, circular and radial fibers after CABG has improved in all patients. Only SR of radial fibers reached normal. In group 1 was received the positive dynamics from the longitudinal S and SR, and SR circular and radial fibers. In group 2 indicators of function of longitudinal and circular fibers remained without negative dynamics, but positive dynamics is observed only from the SR of the radial fibers. The SR of radial fibers in both groups was normalized. Conclusion: improvement of LV function in all patients is due to the group I. It is important to study the LV function in patients with LVA depending on the type of surgery. References 1. Paramonova T.I., Basylev V.V., Vdovkin A.V., Palkova V.A., Karpuchin V.G.
