K notting of a coronary catheter is a well recognized complication of transfemoral cardiac catheterization (1,2). The standard technique for managing this is to straighten the catheter using a stiff wire or, where it is more firmly impacted, to extract it using a snare device introduced via the contralateral femoral artery (2). When these techniques fail, surgical removal or other innovative techniques may be necessary. In the current report, we describe a case of a knotted catheter in the case rePort Sh Mujtaba, F Farquharson, S Arnous, M El-omar.
