Delayed Metallic Embolization of a Cor-Knot Fastener
1Cardiovascular Surgery Clinic, Memphis, Tennessee, United States.
Abstract:
Background The Cor-Knot device is a titanium fastener which is widely used in cardiac valve procedures. Adverse events associated with use of the device have been rare. Case Description A patient underwent robotic mitral valve repair using the Cor-Knot fastener. Five years later, he suffered a cerebral vascular accident secondary to embolization of a metallic foreign body. He had had no other medical procedures which could account for a source of metallic embolization. Conclusion Long-term surveillance after use of the Cor-Knot fastener is limited. Metallic embolization may be possible with this device and warrants awareness within the medical community.

Wood Fasteners
Nails are the most common fasteners, consisting of sharp-pointed metal pins that are driven into wood using a hammer or a mechanical nail gun. They come in a variety of diameters, heads, and lengths. Nailing techniques include...
Steel Fastening Techniques
Rivets are cylindrical steel fasteners with a specially designed head. During application, rivets are heated until white-hot and then inserted through pre-drilled holes in the steel sections. A pneumatic hammer is used to shape the exposed end into a second head, securing the sections together.
