I have enclosed a link to a 14 minute video on an anterior leaflet augmentation performed via a minimally invasive approach. I have used bovine pericardium in all but one case in which I used autologous, untreated pericardium. I believe that this technique should be performed with bovine pericardium or glutaraldehyde treated pericardium. There is a new product on the market called CardioCel which may also be promising. A recent paper presented at ISMICS in Boston by Dr. Guy demonstrated that there was a high incidence of patch complications utilizing Corematrix.
