• Transfemoral tricuspid valve replacement and one-year outcomes: the TRISCEND study

  European Heart Journal · 2023 · 238 citations

  BACKGROUND AND AIMS: For patients with symptomatic, severe tricuspid regurgitation (TR), early results of transcatheter tricuspid valve (TV) intervention studies have shown significant improvements in functional status and quality of life associated with right-heart reverse remodelling. Longer-term follow-up is needed to confirm sustained improvements in these outcomes. METHODS: The prospective, single-arm, multicentre TRISCEND study enrolled 176 patients to evaluate the safety and performance o…

• Fully automated 3D aortic segmentation of 4D flow MRI for hemodynamic analysis using deep learning

  Magnetic Resonance in Medicine · 2020 · 154 citations

  PURPOSE: To generate fully automated and fast 4D-flow MRI-based 3D segmentations of the aorta using deep learning for reproducible quantification of aortic flow, peak velocity, and dimensions. METHODS: A total of 1018 subjects with aortic 4D-flow MRI (528 with bicuspid aortic valve, 376 with tricuspid aortic valve and aortic dilation, 114 healthy controls) comprised the data set. A convolutional neural network was trained to generate 3D aortic segmentations from 4D-flow data. Manual segmentation…

• Quantitative Stress First-Pass Perfusion Cardiac MRI: State of the Art

  Radiographics · 2025-02-20 · 10 citations

  review

  Quantitative stress perfusion cardiac magnetic resonance (CMR) imaging is an emerging and powerful clinical tool that improves the diagnostic accuracy of stress perfusion CMR for noninvasive assessment of epicardial coronary artery disease, microvascular dysfunction, aortic stenosis, and cardiac allograft vasculopathy.

• Delta Radiomics and Tumor Size: A New Predictive Radiomics Model for Chemotherapy Response in Liver Metastases from Breast and Colorectal Cancer

  Tomography · 2025-02-20 · 6 citations

  articleOpen access

  Background/Objectives: Radiomic features exhibit a correlation with tumor size on pretreatment images. However, on post-treatment images, this association is influenced by treatment efficacy and varies between responders and non-responders. This study introduces a novel model, called baseline-referenced Delta radiomics, which integrates the association between radiomic features and tumor size into Delta radiomics to predict chemotherapy response in liver metastases from breast cancer (BC) and co…
