Key result
Percutaneous J-shaped catheter technique enables nonsurgical retrieval of a knotted coronary catheter.
Why the study?
Previously reported techniques to untie knots in Type III, No. 8 French left coronary artery catheters were unsuccessful, necessitating alternative nonsurgical removal methods.
Describes a percutaneous technique using a second 'J' shaped catheter to immobilize and remove a knotted coronary catheter without surgery.
Answers are grounded in this paper and cite their sources.
May offer nonsurgical option for knotted coronary catheters after failed untying; leaves open need for validation and standardized protocols.
Knotting of a Type III, No. 8 French left coronary artery catheter is reported. Previously reported techniques of “untyng” the knot in similar catheters was unsuccessfully attempted. Nonsurgical removal of the catheter was accomplished following immobilization of the knot with a second percutaneously inserted “J” shaped catheter.

Harry L. Stein (1973) studied this question. Nonsurgical removal of a knotted coronary artery catheter was successfully achieved by immobilizing the knot with a second percutaneously inserted 'J' shaped catheter.
