The ExoVasc® Personalised External Aortic Root Support is a revolutionary new device. It is designed to manage aortic dilation in people with Marfan syndrome and related genetic conditions. The ExoVasc® is placed around the ascending aorta where it provides support to the patient’s own aorta and aortic valve and is designed to prevent enlargement and rupture. A further application is in the Ross Operation where the ExoVasc® is used to manage dilation of the transplanted pulmonary valve when replacing the first part of the aorta. This innovation developed by Exstent Limited sets a new standard in the surgical management of the dilated aorta. More than 500 patients have now received their ExoVasc® support and its effectiveness is proven by a total of over 1,400 patient-years’ experience gained during the past 17 years.
