Cardiac valve disease
Romain Capoulade, Solena Le Scouarnec, Jean Mérot, Jean-Jacques Schott and Thierry Le Tourneau
Cardiac valve diseases are the one of most frequent cardiovascular diseases and are associated with important mobi-mortality. There is currently no medical therapy available to at least slow down the progression of these pathologies, the only option remaining is to replace or repair the diseased valve, via surgical or transcatheter approaches.In our group, we develop a translational research program, from the genetics and basic researches to the clinical setting, designed to improve our understanding on native valve diseases, such as calcific aortic valve stenosis (CAVS) and mitral valve prolapse (MVP), as well as structural bioprosthetic valve degeneration.
This program is declined around 3 main axes:
- One of the largest worldwide cohort of patients with valve diseases, with the recruitment of sporadic cases and large familial pedigrees.
- Genetic investigations on familial and isolated cases presenting different degrees of valve diseases.
- Study of the pathophysiological mechanisms leading to the initiation and progression of these cardiac valve diseases
- AAP "Recherche fondamentale et clinique sur les maladies cardiovasculaires" (Fondation de France; 2022-2025) - Impacts of Lipid in the Structural biological prosthetic Valve Degeneration (Romain Capoulade)
- Bourse A. Castaigne (SFC; 2021-2022) – Study of the Molecular Mechanisms Involved in the Development and Progression of Mitral Valve Prolapse (Romain Capoulade)
Romain Capoulade hold this award in 2021 for his on-going work on the molecular mechanisms involved in the development and progression of mitral valve prolapse (MVP).
This support will allow him to pursue the study on the role of inflammation and immune response in the process leading to MVP, with a specific attention to the additive impact of stress-related mechanisms.

- Connect Talent - Advanced Multimodality Imaging Program and Translational Research in Chronic Cardiovascular Diseases (Romain Capoulade)
The cornerstone of genetic investigations is the precise phenotypic characterization. Emergence of a new research axis focused on the development of bio-imaging core facility and expertise in image analysis provide support to the research programs of the team, as well as offer the opportunity to develop new translational and innovative projects.
