Alexandre Altes
Dr. Alexandre Altes is a cardiologist specializing in cardiac imaging (echocardiography,MRI), a Senior Lecturer at the Free Faculty of Medicine of Lille. He works on the study of prognostic criteria in native valvular heart diseases through multimodal imaging, as part of his doctorate supervised by Prof. Sylvestre Maréchaux. Trained in cardiac MRI, certified by EACVI, Fellow of the ESC, he combines academic training, diagnostic expertise, and clinical research to improve the accuracy and prognostic value of imaging examinations.
