“…Some of the studies on VFM pointed out that the diastolic EL value was positively correlated with the E/e′, and the higher E/e′ was capable of reflecting the increase in the filling pressure of the left ventricle during diastole. By changing the blood flow velocity, the massive high‐speed blood flow increases EL, and EL might be a useful parameter to evaluate the diastolic function of the left ventricle 17 . E/e′ could be utilized as a predictor evaluation of diastolic EL value, indicating that diastolic dysfunction and increased filling pressure may play a contributing role in energy loss.…”

Objectives To evaluate the left ventricular energy loss (EL), energy loss reserve (EL‐r), and energy loss reserve rate in patients with mild coronary artery stenosis by using vector flow mapping (VFM) combined with exercise stress echocardiography. Methods A total of 34 patients (case group) with mild coronary artery stenosis and 36 sex and age matched patients (control group) without coronary artery stenosis according to coronary angiogram were prospectively enrolled. The total energy loss (ELt), basal segment energy loss (ELb), middle segment energy loss (ELm), apical segment energy loss (ELa), energy loss reserve (EL‐r), and energy loss reserve rate were recorded in the isovolumic systolic period (S1), rapid ejection period (S2), slow ejection period (S3), isovolumic diastolic period (D1), rapid filling period (D2), slow filling period (D3), and atrial contraction period (D4). Results Compared with the control group, some of the EL in the resting case group were higher; some of the EL in the case group were lower after exercise, and those during D1 ELb and D3 ELb were higher. Compared with the resting state, the total EL and the EL within the time segment in the control group were higher after exercise, except during D2 ELb. In the case group, except for during D1 ELt, ELb and D2 ELb, the total and segmental EL of each phase was mostly higher after exercise (p < .05). Compared with the control group, most of the EL‐r and EL reserve rates in the case group were lower (p < .05). Conclusion The EL, EL‐r, and energy loss reserve rate have a certain value in the evaluation of cardiac function in patients with mild coronary artery stenosis.

“…The change of diastolic vortices in the type 2 diabetic patients with early CKD was similar to that in non-CKD patients with diastolic dysfunction. The early diastolic vortex had a small size and weak intensity with no statistical difference, and the late diastolic vortex became significantly stronger in non-CKD patients with diastolic dysfunction [ 29 , 32 ]. Our data further confirmed that the LV filling parameters were closely associated with the behavior of diastolic vortices.…”

Background Diabetes is the leading cause of chronic kidney disease (CKD) and contributes to an elevated incidence of diastolic dysfunction in the early stages of CKD. Intracardiac vortex is a novel hemodynamic index for perceiving cardiac status. Here, we visualized left ventricular (LV) vortex characteristics using vector flow mapping (VFM) in type 2 diabetic patients with early CKD. Methods This cross-sectional study included 67 controls and 89 type 2 diabetic patients with stages 2-3a CKD. All subjects underwent transthoracic echocardiographic examination. LV anterior vortex during early diastole (E-vortex), atrial contraction (A-vortex) and systole (S-vortex) were assessed using VFM in the apical long-axis view. Its relation to glycemia or LV filling echocardiographic parameters were further analyzed using correlation analysis. Results Type 2 diabetic patients with early CKD had a small area (439.94 ± 132.37 mm2 vs. 381.66 ± 136.85 mm2, P = 0.008) and weak circulation (0.0226 ± 0.0079 m2/s vs. 0.0195 ± 0.0070 m2/s, P = 0.013) of E-vortex, but a large area (281.52 ± 137.27 mm2 vs. 514.83 ± 160.33 mm2, P ˂ 0.001) and intense circulation (0.0149 ± 0.0069 m2/s vs. 0.0250 ± 0.0067 m2/s, P < 0.001) of A-vortex compared to controls. CKD patients with poorly controlled hyperglycemia had stronger A-vortex (area: 479.06 ± 146.78 mm2 vs. 559.96 ± 159.27 mm2, P = 0.015; circulation: 0.0221 ± 0.0058 m2/s vs. 0.0275 ± 0.0064 m2/s, P < 0.001) and S-vortex (area: 524.21 ± 165.52 mm2 vs. 607.87 ± 185.33 mm2, P = 0.029; circulation: 0.0174 ± 0.0072 m2/s vs. 0.0213 ± 0.0074 m2/s, P = 0.015), and a longer relative duration of S-vortex (0.7436 ± 0.0772 vs. 0.7845 ± 0.0752, P = 0.013) than those who had well-controlled hyperglycemia. Glycemia, and E/A (a LV filling parameter) were respectively found to had close correlation to the features of A-vortex and S-vortex (all P < 0.05). Conclusions Abnormal LV vortices were detected in type 2 diabetic patients with early CKD using VFM, especially in those who neglected hyperglycemic control. LV vortex might be a promising parameter to slow or halt the hyperglycemia-induced diastolic dysfunction in early CKD.

“…VFM is a technique that reflects changes in the flow field within the cardiac chambers and detects cardiac pathophysiological and functional changes from a hemodynamic perspective of intraventricular blood flow field changes[ 31 - 33 ]. Color Doppler converts the acquired two-dimensional velocity flow field distribution into two flow components: vortex and basal flow[ 34 ].…”

Regional pressure differences between sites within the left ventricular cavity have long been identified, and the potential clinical value of diastolic and systolic intraventricular pressure differences (IVPDs) is of increasing interest. This study concluded that the IVPD plays an important role in ventricular filling and emptying and is a reliable indicator of ventricular relaxation, elastic recoil, diastolic pumping, and effective left ventricular filling. Relative pressure imaging, as a novel and potentially clinically applicable measure of left IVPDs, enables early and more comprehensive identification of the temporal and spatial characteristics of IVPD. In the future, as research related to relative pressure imaging continues, this measurement method has the possibility to become more refined and serve as an additional clinical aid that can replace the gold standard cardiac catheterization technique for the diagnosis of diastolic dysfunction.
