Both ECV values of DECT and SECT correlated well with the histological CVF results (R=0.935 and 0.952 for the DECT-ECV and SECT-ECV; all P&lt;0.001; n=13). Bland-Altman plots showed no significant differences between DECT- and SECT-ECV.<br /><br /> DECT-ECV correlated well with both SECT-ECV and histology, showing the feasibility of DECT in evaluating doxorubicin-induced diffuse myocardial interstitial fibrosis.<br /><br />DECT-ECV correlated well with both SECT-ECV and histology, showing the feasibility of DECT in evaluating doxorubicin-induced diffuse myocardial interstitial fibrosis.<br /><br /> Cardiac involvement is a major contributor of morbidity and mortality in Fabry disease (FD). Early detection and accurate evaluation of the disease progression is important in management. Cardiovascular magnetic resonance (CMR) derived feature fracking (FT) is a validated quantitative method of assessing myocardial deformation which may reflect early changes of myocardial function and track disease severity. We sought to evaluate the utility of CMR-FT as a measure of myocardial dysfunction in FD.<br /><br /> Twenty FD patients (12 males, 40.8±14.9 years) and 20 age and sex matched healthy controls (10 males, 40.5±7.2 years) were prospectively enrolled. Subjects underwent CMR including cine, pre-/post-contrast T1 mapping and late gadolinium enhancement (LGE). FD patients were divided into three groups; group 1 patients without left ventricular hypertrophy (LVH) and LGE negative; group 2 patients with LVH positive, LGE either positive or negative; group 3 patients with LGE positive, LV wall thinning and heart failure. 1 value (r=0.783, P&lt;0.01).<br /><br /> CMR strain imaging identifies myocardial deformation in FD in different stages. Strain imaging can track disease severity and may be an alternative method for follow-up of FD patients.<br /><br />CMR strain imaging identifies myocardial deformation in FD in different stages.

Most pregnant women adapt well to these gradual hemodynamic changes. However, in women with congenital heart disease or other structural heart disease, adaptation to theses sudden hemodynamic changes is difficult, and heart failure or arrhythmia can get aggravated. This study shares our experiences on the outcomes of pregnancy in patients with structural heart disease.<br /><br /> From January 2007 to December 2016, we reviewed the medical records of all pregnant women with structural heart disease who received obstetric care at the Sejong General Hospital.<br /><br /> During the study period, 103 pregnancies were observed in 79 women with structural heart disease. Of the 103 pregnancies, 55 were primiparous and 48 were multiparous. Echocardiography performed before pregnancy revealed that 52 patients had moderate to severe valvular regurgitation and 38 patients had moderate to severe valvular stenosis; 22 patients had mechanical valves and 5 patients had pulmonary hypertension. Overall, there were 9 maternal cardiac events, 7 obstetric events and 19 neonatal events. Pulmonary embolic events occurred only in 1 case; 77 deliveries were made, and 26 pregnancies did not last. Among 77 deliveries, 55 patients delivered by cesarean section (C/S) (71.43%). C/S in 16 of 55 patients was performed due to the maternal hemodynamic risk.<br /><br /> Overall complications associated with pregnancy in women with structural heart disease were very high at 28.16%. However, it is hoped that maternal and neonatal outcomes will be improved through careful observation and preparedness for anticipated complications.<br /><br />Overall complications associated with pregnancy in women with structural heart disease were very high at 28.16%.

We sought to determine TVA geometry and dimensions in controls and assess the changes that occur in patients with severe primary (PMR) and secondary (SMR) mitral regurgitation without TR.<br /><br /> We analyzed cardiac computed tomographic angiography (CCTA) of 125 consecutive subjects 50 controls with normal coronary CCTA and no valvular dysfunction, 50 PMR patients referred for robotic repair, and 25 SMR patients referred for transcatheter therapy. Patients with &gt;2+ TR on echocardiography were excluded. Annular measurements were performed using dedicated software and compared. Correlations and determinants of TVA dimensions were analyzed.<br /><br /> Patients with SMR were older and had significantly more comorbidities. In controls, the TVA was larger and more planar and eccentric compared to the MV annulus (all P&lt;0.01). Dimensions of both annuli correlated significantly (r≥0.5; P&lt;0.001 for all dimensions) in controls and patients with severe MR. In both PMR and SMR, the TVA enlarged in all dimensions (P&lt;0.01) with a trend towards becoming more circular. On multivariable regression, the MV annular area was the primary determinant of the TVA area (adjusted β=0.430, P&lt;0.001).<br /><br /> Substantial changes in TVA dimensions are encountered in patients with severe MR even in the absence of severe TR such that TVA and MVA dimensions remain correlated. Close attention to the TVA in patients with severe MR is warranted.<br /><br />Substantial changes in TVA dimensions are encountered in patients with severe MR even in the absence of severe TR such that TVA and MVA dimensions remain correlated.

[https://www.selleckchem.com/products/ipilimumab.html Ipilimumab chemical structure] Quantitative diagnosis from the dynamic SPECT and a flow diagram was automatically obtained by the dedicated software and compared with the result of semi-quantitative analysis with gated MPI using the angiographic stenosis as the reference standard.<br /><br /> When stenosis ≥50% was considered at the participant level, the sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV) and accuracy (AC) of the quantitative diagnosis were higher than semi-quantitative method as (84.4% <br /><br /> 65.6%, 88.2% <br /><br /> 70.6%, 93.1% <br /><br /> 80.
