Sylvestre Marechaux
Professor Sylvestre Maréchaux is a renowned academic cardiologist, specialized in valvular heart disease, cardiomyopathies, and heart failure. A graduate of the Faculty of Medicine in Lille, he defended his doctoral thesis in 2007, focusing on the contribution of biomarkers to the diagnosis of aortic stenosis. He subsequently earned an Inter-University Diploma in cardiovascular imaging (MRI, CT) in 2010, and in the same year obtained his Habilitation to Supervise Research (HDR).
He is currently Head of the Cardiology Department at the Groupe Hospitalier de l’Institut Catholique de Lille (GHICL) and Director of DATA-CŒUR. A Professor at the Faculty of Medicine, Midwifery and Health Sciences of Lille, he also serves as Vice-Dean for Research Promotion. He is Treasurer of the Cardiovascular Imaging Section of the French Society of Cardiology and a member of the Education Committee of the European Association of Cardiovascular Imaging (EACVI) in Echocardiography.
His scientific activity focuses on advanced cardiac imaging (echocardiography, MRI) and the functional and prognostic assessment of cardiovascular diseases. He is the author of numerous publications in international peer-reviewed journals and is actively involved in translational research projects. He regularly supervises doctoral theses and the work of young researchers, contributing to the training of a new generation of clinician-scientists.
At the head of his research team, he is dedicated to advancing the understanding of complex cardiovascular diseases, integrating technological innovations and personalized approaches to medicine.
