Key result
A 41-year-old male suffered a cerebral vascular accident secondary to the delayed embolization of a titanium Cor-Knot fastener 5 years after robotic mitral valve repair.
Case Report (n=1)
The Cor-Knot fastener used in cardiac valve procedures may carry a risk of delayed metallic embolization leading to stroke.
Alerts clinicians to possible late Cor-Knot embolization in post-valve stroke patients; leaves open long-term device safety surveillance needs.
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.
