A “Left atrial mitral-valve prosthesis” for interventional mitral valve (re)placement

Objective: Due to anatomical reasons, interventional placement of heart valve prosthesis in mitral position is challenging. We aimed for a totally new approach, inserting a valve-bearing prosthesis strutting on the entire left atrial wall, the mitral ring and the pulmonary veins. A design study was performed and the resulting prosthesis evaluated in the animal.
