Myocardial Tissue Tagging

Background: Echocardiographic (EC) indices of mechanical dyssynchrony (MD) are based largely upon longitudinal strain, whereas magnetic resonance imaging myocardial tissue tagging (MRI-MT) assessment is based on circumferential strain, the latter being the primary direction of myocardial contraction. Methods: We sought to compare cardiac MRI studies with an EC protocol using 2D imaging, tissue Doppler imaging (TDI), and M-mode in 32 subjects. Absolute strain, time to peak strain in 6 segments, TDI septal-to-lateral delay (SLD; MD if ≥ 70 ms), and M-mode septal-to-posterior wall motion delay (SPWMD; MD if ≥ 130 ms) were measured and compared to the MRI-MT-based CURE (circumferential uniformity ratio estimate, CURE; 0 –1, 0 = asynchrony, 1 = perfect synchrony; MD if < 0.75), which recently has been shown to predict clinical CRT response. Results: The 8 control subjects (normal QRSd; CURE 0.975 ± 0.01; SLD 26 ± 27 ms) had less MD by MRI-MT (p = 0.0001) and TDI (p = 0.04) as compared to 24 subjects with ejection fraction ≤ 35% (QRSd 135 ≤ 35 ms; CURE 0.695 ± 0.17; SLD 59 ± 39 ms). There was a moderate correlation between TDI and MRI-MT (R = 0.62), with a discordance rate of 22% overall and 25% in cardiomyopathy subjects, in some cases due to abnormal CURE with normal SLD and, in others, normal CURE with abnormal SLD. The M-mode assay (SPWMD) could not be assessed in 10 patients with septal akinesis (AK), although there was MD by TDI and MRI-MT in most of these subjects. In the patients without AK, the discordance rate between TDI and M-mode was 33%. Conclusions: MRI-MT assessment of circumferential strain and MD is complementary to TDI with a good correlation, but also a significant discordance rate.

The obstructive of paper was to study and match clinical symptoms of chronic obstructive pulmonary disease, laboratory and instrumental analyses data, and data obtained from myocardial Tissue Doppler Imaging. Sixty four patients four patients with chronic obstructive pulmonary disease were examined. It was discovered that information obtained through myocardial Tissue Doppler Imaging is in fact early evidence of pulmonary heart disease available at the pre-clinical stage (functional changes are observed before clinical symptoms).
