4D Flow MRI Reduces Scan Times and Improves Data Consistency in Patients with Total Cavopulmonary Connection (Fontan)
Impact: 4D flow MRI significantly streamlines Fontan circulation
assessment by reducing exam time and improving data quality. Its enhanced
reliability and efficiency support broader clinical adoption, optimizing patient
comfort and workflow in monitoring long-term complications after Fontan procedure.

Fast free breathing cine imaging with deep learning super-resolution reconstruction in congenital heart diseases
Impact: Fast free-breathing cine imaging with super-resolution
reconstruction enables faster, high-quality cardiac imaging without
breath-holding. This approach may reduce the need for sedation and improve
workflow and accessibility of CMR, especially in pediatric and complex CHD
populations.

Dual inversion recovery for optimized MR lymphangiography in Fontan circulation vs heavily T2-weighted imaging
Impact: DIRECTION lymphangiography offers a safe, noninvasive, and reproducible technique for high-resolution visualization of lymphatic congestion in Fontan patients, enabling clearer delineation of lymphatic pathways and providing new opportunities for comprehensive evaluation, improved diagnosis, and individualized treatment planning.

Integrated Anatomical-Hemodynamic Analysis in Bicuspid Aortic Valve
Impact: Automated
co-registration of CE-MRA and 4D flow MRI enables spatially resolved analysis
of anatomical-hemodynamic relationships in BAV aortopathy. This automated pipeline provides a framework to test whether integrated features improve risk prediction beyond current diameter-based criteria in longitudinal cohort studies.

Impact of water exchange on estimates of myocardial blood flow & ECV using DCE-MRI in patients treated for aortic stenosis
Impact: Water exchange has negligible impact upon estimates of myocardial blood flow and extracellular volume fraction obtained using dynamic contrast-enhanced MRI even when relatively high doses of contrast agent are used.

Measurement of myocardial extracellular volume fraction and cardiomyocyte diameter before after aortic valve replacement
Impact: For the first time using contrast-enhanced MRI the intracellular lifetime of water, an index of cardiomyocyte diameter, has been shown to decrease following aortic valve replacement in patients with severe aortic stenosis.

Correlations Between Radiomic Features and Myocardial Strains Derived from Cardiac MRI in Repaired Tetralogy of Fallot
Impact: The rTOF patients with advanced disease
progression exhibited a globally homogeneous radiomic feature pattern with subtle local variations. The differential relationships between features and contractile function were shown in
different disease progressions, with thresholds for PR, RV dilation, and function.

Achieving Whole-Heart CMR in a Single Breath-Hold with Deep Learning Super-Resolution
Impact: Our deep learning model enables single breath-hold whole-heart imaging with automated segmentation, achieving image quality and quantitative measurement accuracy comparable to conventional 3D high-resolution acquisitions, but in a clinically practical breath-hold of about 9 seconds.

Evaluating TFCE-based permutation tests for the patch-wise analysis of WSS maps in the ascending aorta
Impact: This study promotes
the adoption of TFCE-based permutation test for the local analysis of WSS on
the aortic wall. The study may encourage the use of TFCE-based permutation also
for volumetric hemodynamic parameters derived from 4D Flow MRI.

Uncertainty-Guided Active Learning for Access Route Segmentation and Planning in Transcatheter Aortic Valve Implantation
Impact: This work enables accurate, low-annotation CMR-based vascular assessment for TAVI, reducing dependence on CT and contrast agents while achieving precise vessel segmentation and diameter quantification through uncertainty-guided active learning, improving access route planning in patients with renal impairment.

2D and 4D Flow CMR versus Ultrasonic Cardiography in Assessing Mitral Regurgitation Severity
Impact: Four-dimensional flow cardiac magnetic resonance (CMR) allows accurate,
reproducible quantification of mitral regurgitation independent of left
ventricular volume. This supports improved clinical decision-making,
personalized intervention planning, and the development of advanced imaging approaches
for complex or eccentric valvular disease.

Anatomy Derived Aortic Hemodynamics Using Physics-Informed Deep Learning: Multi-Site Cross-Vendor Validation
Impact: AI-inferred 4D Flow enables fast, anatomy-based estimation of aortic hemodynamics with strong agreement to in-vivo phase-contrast MRI. This approach could streamline flow quantification, reduce scan time, and expand access to functional cardiovascular imaging.

Exploring the Effect of Fontan Fenestration Size using Cardiovascular MRI, Catheterization, and Computational Fluid Dynamics
Impact: The computational identification of a patient-specific, optimal Fontan fenestration configuration holds the potential to aid surgical planning of the fenestrated Fontan procedure, ultimately aiming to enhance the hemodynamic outcomes of this complex cardiac surgery.

Radiomic Signatures of Structural Alterations in Fontan Patients
Impact: Radiomics analysis of CINE
CMR images can detect microscopic myocardial differences in Fontan patients,
and the selected features may serve as early biomarkers of myocardial
dysfunction.

The Feasibility of Lung T2* Mapping for Pulmonary Status Monitoring in Pediatric Patients with Congenital Heart Disease
Impact: Pulmonary T2* mapping using 3D UTE sequence
is
feasible in pediatric CHD patients and offers a rapid, contrast-free MRI
biomarker of altered pulmonary oxygenation and perfusion.
This provides new insights into lung physiology and a potential tool for
non-invasive monitoring.
