COVADIS Pilot Trial: COseal in Ventricular Assist DevIceS (COVADIS)
A Controlled, Single-Center Clinical Pilot Study to Evaluate the Performance of CoSeal as a Barrier for Adhesion Prevention in Patients Submitted to Ventricular Assist Device VAD)
Study Overview
Status
Detailed Description
In the past decade the use of ventricular assist devices) (VADs) for bridging to heart transplantation (HTx) or, in some cases, to recovery of the ventricular function has increased and, during the same time, the duration of the implantation period has lengthened dramatically. When removing VADs after a long period, surgeons face severe pericardial adhesions at the mediastinum level and of the surrounding tissue due to the inflammatory response. During resternotomy, dissection of these adhesions increases surgical time and can be a source of lesions on the cardiac or vascular structures and of severe bleeding at the moment of transplantation or when the device is removed.
Many products have been used to prevent or reduce adhesions but an ideal antiadhesive treatment has remained elusive. CoSeal®, a licensed synthetic hydrogel (Baxter, USA) has been shown to reduce pericardial adhesions in a limited series of reoperations.

Measure Description |
Time Frame |
---|---|---|
Bleeding
Time Frame: At the moment of VAD-Removal/Transplantation
