The objective of the RHU ICELAND is to develop a new solution for annuloplasty of the mitral valve by transfemoral approach integrating an Intra Cardiac Ultrasound. Such a solution can be performed while the heart is beating, without cardiopulmonary bypass, thus providing a first-stage mitral valve repair solution for patients considered high risk who are not eligible for open surgery, and further for most patients requiring mitral valve repair. .
