M.M. Dolzhenko, N.M. NosenkoProspective study of myocardial left ventricular function after coronary artery bypass grafting with aneurysmectomy by tissue Doppler imaging.

The aim of the study was to compare left ventricular (LV) global contractility data in the relation to myocardial longitudinal kinetics amplitude in patients with postinfarction cardiosclerosis and LV aneurysm and to evaluate restitution of myocardial function in 12 months after coronary artery bypass grafting (CABG) combined with LV aneurysmectomy. We examined 148 postinfarction patients before and after CABG with LV aneurysmectomy.
Left ventricular postinfarction aneurysm was verified by transthoracic EchoCG, multislice contrast computer tomography and coronary angiography. All patients underwent EchoCG with tissue Doppler imaging before, in 6
and 12 months after surgery. Significant correlation was found between septal mitral annulus systolic peak Sm velocity during tissue Doppler imaging and global contractility (r=0.57). Sm amplitude reflects LV longitudinal contractility with 82 % sensitivity and 72 % specificity.
