Left ventricular diastolic function and atrial sphericity parameters were studied in 503 healthy Chinese adults. Men showed significantly different values in parameters such as LACI (0.19 vs 0.20) and LASI (0.52 vs 0.59) compared to women. These findings are important for standardized interpretation of cardiac magnetic resonance parameters in clinical practice

The cardiac diffusion tensor imaging (cDTI) technique with up to 6th order motion compensation was studied. The results show that 4th order compensation is necessary for successful diastolic acquisitions, with mean diffusivity values of (1.73 ± 0.19) × 10-3mm2∕s. This enables reliable quantification of myocardial microstructural changes between systole and diastole, a step towards clinical translation of dynamic cDTI.

The role of multimodal imaging in transcatheter mitral valve interventions for secondary mitral regurgitation was studied. Imaging criteria for patient selection and key findings after device implantation were examined. This is important for patient selection and follow-up in clinical practice

PET/CT and CMR techniques were compared for myocardial perfusion evaluation. Both modalities offer high accuracy for detecting flow-limiting coronary stenoses. This is important in clinical practice for improving diagnosis and management of coronary artery disease

The effect of semaglutide was studied in preclinical models of heart failure with preserved ejection fraction. It was found that semaglutide improves diastolic function and reduces cardiac hypertrophy by 30% and left ventricular filling pressure by 60% without significant weight loss. This is important because it suggests that semaglutide may be beneficial in clinical practice for treating this condition

In 52 invasively confirmed HFpEF patients (multicentre DECIPHER study), corrected native T1 was associated with passive stiffness (β) and T2 with active relaxation (τ), independent of end-diastolic pressure. Mapping separated mild and severe diastolic dysfunction phenotypes that filling pressure did not; the authors consider this hypothesis-generating.

In 49 patients with dilated cardiomyopathy and 23 controls, a non-contrast CMR technique showed lower myocardial oxygen extraction fraction (50.3% vs 57.6%) and lower mechano-energetic efficiency (22.9% vs 46.0%), with higher total oxygen consumption. Efficiency correlated with LVEF and global longitudinal strain. Feasibility study.

In 1,675 subjects from a national referral centre, native T1 ≤1,050 ms made cardiac involvement unlikely (93% sensitivity, 84% specificity) and ≥1,100 ms identified overt ATTR-CM (75% and 88%). ECV-calibrated T1 strata reproduced a 3-year mortality gradient; ECV remains preferred when contrast is available, and thresholds need local recalibration.

J Cardiovasc Magn ResonPMID 42800640
The feasibility of real-time cardiac magnetic resonance (CMR) for ventricular quantification in arrhythmic patients was studied. The results showed that the technique can reveal functional heterogeneity in patients with premature ventricular contractions (PVC), with broader and sometimes bimodal ejection fraction (EF) distributions. This may be important in clinical practice to improve the evaluation of cardiac function in arrhythmic patients.
