This article provides information about a clinical trial conducted by Lille Catholic University. The trial, NCT06420895, aims to create a data warehouse based on care data of patients with aortic insufficiency admitted to the Groupement des Hopitaux de l'Institut Catholique de Lille (GHICL) since 2011. The purpose of this project is to enable the utilization of this data for research purposes. The trial is observational in nature and will collect data retrospectively from medical records and various care software. The data will be collected by authorized staff and will not impact the patient's care. The trial is currently active but not recruiting new participants, with an estimated completion date of December 31, 2033. The eligibility criteria for participants include being adults with chronic aortic insufficiency and not having certain medical conditions or previous surgeries. The study is not accepting healthy volunteers. The responsible party for the trial is Lille Catholic University, and the principal investigator is Alexandre Altes. [Extracted from the article]
