“…Direct comparison of velocities between echo and MRI has been done for 2D one-directional VE MRI by Ajmone Marsan et al (11). They reported a small, nonsignificant difference between both techniques, but with wide limits of agreement (i.e., À14 cm/s to þ13 cm/ s).…”

“…LV diastolic function was studied from the transmitral flow rate graphs, assessed with both 3D three-directional and 2D onedirectional VE MRI as previously described ( Fig. 1) (7,(9)(10)(11). Acquisition parameters for 3D three-directional MRI were: repetition time (TR) ms/echo time (TE) ms 7.5/4.3; flip angle (FA), 10 ; field of view (FOV), 370 mm; 3D volume imaging with 48-mm slab thickness reconstructed into 12 Â 4-mm sections; in-plane acquisition resolution 2.9 Â 3.8 mm, Figure 1.…”

Purpose: To compare parameters describing left ventricular (LV) diastolic function obtained with three-dimensional (3D) three-directional velocity-encoded (VE) MRI with retrospective valve tracking and two-dimensional (2D) one-directional VE MRI in patients with ischemic heart failure. Second, to compare classification of LV diastolic function, and in particular for discriminating restrictive filling patterns, with both MRI techniques versus Doppler echocardiography. Materials and Methods:The 3D and 2D VE MRI early (E) and atrial (A) peak flow rate indices, determined from transmitral waveform analyses, were compared. Also, net forward flow volume per cycle and transmitral regurgitation fraction were determined. Agreement in classifying diastolic filling patterns between 3D and 2D VE MRI versus Doppler echocardiography was evaluated using kappa statistics.Results: The 3D three-directional VE MRI with retrospective valve tracking was statistically significantly different from 2D one-directional VE MRI for net forward flow volume and regurgitation fraction through the mitral valve and all parameters describing the diastolic waveform filling pattern, except for the E deceleration time and E/A filling ratio. Kappa-agreement between 3D three-directional VE MRI with retrospective valve tracking and echocardiography for classifying diastolic filling patterns was superior to 2D one-directional VE MRI and echocardiography (i.e., k ¼ 0.91 versus k ¼ 0.79, respectively). Conclusion:The 3D three-directional VE MRI with retrospective valve tracking better describes LV diastolic function as compared to 2D one-directional VE MRI in patients with ischemic heart failure.

“…However, despite these methodological developments and the recent technological improvements in PC-CMR sequences, the use of CMR in clinical evaluation of diastolic function remains limited because of the lack of automated methods designed for the analysis of PC images. Indeed, most of the PC-CMR studies previously presented in the literature were based on manual positioning of ROIs on each phase of the cardiac cycle [8][9][10][11][12][13][14][15]. This manual positioning is time-consuming [30] and subjective [8], leading to inter-and intra-operator variability, as reflected by the previously reported variability coefficient of 10% [31].…”

“…Although CMR is known as the modality of choice for the evaluation of global LV function [20,21], systolic function and myocardial viability [22,23], Doppler echocardiography remains the clinical reference for the evaluationo fd i a s t o l i cd y s f u n c t i o n [4,24,25]. Several CMR studies, based on volume variation curves extracted from cine images [26][27][28][29] or on velocity and flow rate curves extracted from PC images [8][9][10][11][12][13][14][15], reported capabilities of this modality for the assessment of diastolic function. However, despite these methodological developments and the recent technological improvements in PC-CMR sequences, the use of CMR in clinical evaluation of diastolic function remains limited because of the lack of automated methods designed for the analysis of PC images.…”

“…Furthermore, several studies demonstrated the usefulness of phase-contrast (PC) CMR in the measurement of some of the aforementioned conventional diastolic parameters [6][7][8]. However, these analyses were mostly based on manual positioning of regions of interest (ROIs) within the transmitral flow area or the myocardium on multiple phases [8][9][10][11][12][13][14][15]. This manual positioning of ROIs is time-consuming and operator-dependent.…”

Objectives: The purpose of this study was to evaluate the effects of statin therapy on myocardial function as measured with echocardiography with tissue Doppler imaging (TDI) and strain imaging (SI) independent of its lipid-lowering effect. Background: Statin use is known to improve outcomes in the primary and secondary prevention of ischemic heart disease, but their use is also associated with myopathy, muscle weakness and in rare cases, rhabdomyolysis. We sought to evaluate whether TDI and SI is able to identify changes in myocardial function associated with statin use. Methods: Myocardial function was evaluated in 28 patients via echocardiography with TDI and SI. We identified 12 patients (5 females) without overt cardiovascular disease (including hypertension, smoking, and diabetes) that were on statin therapy and compared their echocardiographic findings with 16 (12 females) age, sex, and cholesterol-profile-matched controls. Tissue Doppler imaging parameters of diastolic (E /A and E/E ) and systolic (S ) function were measured. Regional systolic function was obtained by SI in 4-chamber, 2-chamber, long axis, and average global views. Results: There was no significant difference in myocardial function as measured by Doppler and minor differences as measured via TDI among the 2 groups. There was significantly better function noted with SI in the control group vs the statin group in the 4-chamber (−19.05% ± 2.45% vs −16.47% ± 2.37% P = 0.009), 2-chamber (−20.30% ± 2.66% vs −17.45% ± 4.29% P = 0.03), long axis (−17.63% ± 3.79% vs −13.83% ± 3.74% P = 0.01), and average global (−19.0% ± 2.07% vs −15.91% ± 2.81% P = 0.004) views. Conclusion: Statin therapy is associated with decreased myocardial function as evaluated with SI.
