Conclusion:
Cor-Knot device is currently being used for intracardiac applications
such as implanting pericardial valve in minimally-invasive mitral valve
replacement. We have now utilized the Cor-Knot automated suture
fastening system to close small caliber sites in aorta, such as root
vents, instead of traditional suturing technique for over 4 years
without any suture site complications. In this report we have
demonstrated the safety of using this suture fastener system on large
bore aortic cannulation sites also. One of the benefits of using this
device is that it allows direct visualization of the site as the sutures
are being tightened. This should be considered for direct aortic
cannulation not only in minimally invasive but also open surgery where
this provides controlled deployment under direct vision, rather than
manual suturing with “feeling” the tightness of the knot by the
surgeon’s hands.
