Use of an Automated Suture Fastening Device in Minimally Invasive Aortic Valve Replacement

The authors retrospectively reviewed their minimally invasive aortic valve replacement experience over a three-year period to assess the outcomes in patients undergoing conventional knot tying (n = 39) versus automated knot tying with the Cor-Knot device (n = 53).  Aortic cross-clamp time was approximately 10 minutes shorter in the latter group.  Postoperative mortality and morbidity were comparable, as was valve function at one year.
