The first long-term follow-up after aortic root replacement with the Shelhigh® BioConduit revealed a relatively high rate of death and very high rate of reoperations due to endocarditis, aorto-ventricular disconnection and structural valve failure. This may be potentially connected to the nature of the implanted valved conduit.

Extracellular matrix patches are a potential alternative for pericardial patches for complex reconstructions of atrial structures because of their pliable characteristics and consecutively reduced need for haemostatic stitches.
