Implementation of an epicardial implantable MEMS sensor for continuous and real-time postoperative assessment of left ventricular activity in adult minipigs over a short- and long-term period
The sensing of left ventricular (LV) activity is fundamental in the diagnosis and monitoring of cardiovascular health in high-risk patients after cardiac surgery to achieve better short- and long-term outcome. Conventional approaches rely on noninvasive me ...
Aip Publishing2024Arterial Wave Reflection and Aortic Valve Stenosis: Diagnostic Challenges and Prognostic Significance
Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia, Stamatia Zoi Pagoulatou
IntroductionArterial wave reflection is an important component of the left ventricular afterload, affecting both pressure and flow to the aorta. The aim of the present study was to evaluate the impact of wave reflection on transvalvular pressure gradients ...
FRONTIERS MEDIA SA2022Polygenic Risk Scores for Prediction of Subclinical Coronary Artery Disease in Persons Living With HIV: The Swiss HIV Cohort Study
Jacques Fellay, Christian Axel Wandall Thorball
Background. In people living with human immunodeficiency virus (HIV) (PLWH), individual polygenic risk scores (PRSs) are associated with coronary artery disease (CAD) events. Whether PRSs are associated with subclinical CAD is unknown. Methods. In Swiss HI ...
OXFORD UNIV PRESS INC2022Prognostic Implications of the Novel Pulmonary Hypertension Definition in Patients with Aortic Stenosis after Transcatheter Valve Replacement
Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia, Stamatia Zoi Pagoulatou
Introduction: Pulmonary hypertension (PH), traditionally defined as a mean pulmonary artery pressure (PAP) >= 25 mmHg, is associated with poor outcomes in patients undergoing a transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS). ...
MDPI2022Predicting future myocardial infarction from angiographies with deep learning
Pascal Frossard, Emmanuel Abbé, Olivier Muller, Ortal Yona Senouf, Thabodhan Mahendiran, Stéphane Fournier, Omar Raita, David Meier, Nicolas Dayer, Farhang Aminfar
In patients with stable Coronary Artery Disease (CAD), the identification of lesions which will be responsible of a myocardial infarction (MI) during follow-up remains a daily challenge. In this work, we propose to predict culprit stenosis by applying a de ...
2021Macrophage NCOR1 Deficiency Ameliorates Myocardial Infarction and Neointimal Hyperplasia in Mice
Johan Auwerx, Hongwei Zhu, Yuan Liu, Yan Liu, Shuai Shao
Background NCOR1 (nuclear receptor corepressor 1) is an essential coregulator of gene transcription. It has been shown that NCOR1 in macrophages plays important roles in metabolic regulation. However, the function of macrophage NCOR1 in response to myocard ...
2020How Flow Reduction Influences the Intracranial Aneurysm Occlusion: A Prospective 4D Phase-Contrast MRI Study
Mohamed Farhat, Philippe Reymond, Pierre Bouillot
BACKGROUND AND PURPOSE: Flow-diverter stents are widely used for the treatment of wide-neck intracranial aneurysms. Various parameters may influence intracranial aneurysm thrombosis, including the flow reduction induced by flow-diverter stent implantation, ...
American Society of Neuroradiology (ASNR)2019Computational study of the risk of restenosis in coronary bypasses
Alfio Quarteroni, Christian Vergara
Coronary artery disease, caused by the buildup of atherosclerotic plaques in the coronary vessel wall, is one of the leading causes of death in the world. For high-risk patients, coronary artery bypass graft is the preferred treatment. Despite overall exce ...
Springer Heidelberg2017A computational fluid-structure interaction analysis of coronary Y-grafts
Alfio Quarteroni, Christian Vergara
Coronary artery disease is one of the leading causes of death worldwide. The stenotic coronary vessels are generally treated with coronary artery bypass grafts (CABGs), which can be either arterial (internal mammary artery, radial artery) or venous (saphen ...
Elsevier Sci Ltd2017Thin films for Healthcare Acquired Infections (HAIs) prevention
This thesis addresses the preparation of antibacterial surfaces for hospital facilities taking biomedical thin polymer films, textiles and catheter as probes. Magnetron sputtering is used to apply the coatings leading to fast bacterial inactivation in the ...
