Tissue valves are preferable for patients with end-stage renal disease: an aggregate meta-analysis

This was a meta-analysis of 15 retrospective studies involving 7123 valve prostheses performed in patients with end-stage renal disease (ESRD). The results showed that bleeding complications were significantly higher with mechanical valves and that structural degeneration of tissue valves during the follow-up period was low.  The authors concluded that in patients with ESRD, tissue valves  should be the prosthesis of choice.
