Dr. Mondésert did her medicine training and cardiology specialization in France. Her formation has been completed by a fellowship in electrophysiology at the Montreal Heart Institute (MHI) where she specialized in electrophysiology fields (stimulation and ablation) particularly in adult patients with congenital heart diseases within Dr. Paul Khairy’s team. She also developed an expertise in the extraction of cardiac electronic implantable devices and new technologies as leadless pacemaker or sub-cutaneous ICD. She is finally involved in the AF management program in MHI, from the monitoring (ILR) to the ablation (cryoablation) and LAA occlusion. Since July 2014, she acts as a cardiologist-electrophysiologist-congenitalist at Montreal Heart Institute and as a clinical associate professor in medicine at the Université de Montréal. She is an invited lecturer at international conferences and has been involved in the organization of many congresses. She is involved in the training of electrophysiology fellows and involved in teaching as the director of the electrophysiology fellowship program at the MHI since 2021.
