 abstract={Aim: Ischemic mitral regurgitation-IMR parameters analysis in CMR and TTE, evaluation of the usefulness of CMR in the mitral apparatus assessment also before surgical treatment, analysis of influence of coronary arteries atherosclerosis and myocardial scar on the pathomechanism of IMR. Material and Methods: CMR and TTE was performed in 33 patients (29M,4F;65.9±10.1). Subgroups after anterior MI and inferior MI were analyzed, natriuretic peptides (NP) were measured. Results: The mean values were (CMR vs TTE): RV-17.982 ml ±13.42 vs 24.732 ml ±13.48; RF-20 % ±12 vs 37.8 % ±25; VCW-0.411 cm ±0.13 vs 0.489 cm ±0,15. Correlation between IMR in CMR and TTE were confirmed: RV (r=0.7; p<0.001), RF (r=0.53; p=0.002) i VCW (r=0.49; p=0.004). No difference between LV diameters. LV volumes and wall motion score indices (WMSI) were higher in CMR. Mean values of mitral annulus deformation parameters (MADP) were different, correlations between LV geometry and function parameters, LA volumes and MADP were confirmed. Cuts off severe IMR were: AL≥53.7mm, ML≥46mm, TOTAL≥300.4mm. The differences between subgroups were in syst.mitral annulus area (p=0.008), annular diameters: sept.-lat.(p=0.012), ant.-inf.(p=0.018) and total WMSI. Correlation of NP vs RV (p=0.03), LVEF(p=0.005), LAvolume (p=0.033) were confirmed. Conclusions: RV, RF, VCW are significantly lower in CMR vs TTE. TTE underestimates LV},
 abstract={volumes. CMR and TTE are comparable in LV, LA diameters and EF assessment. In measurement of MADP CMR is more precise. No influence of coronary atherosclerosis and infarct scar on IMR. CMR allows for precise analysis of IMR.},
