How to solve refractory catheter kink in humeral artery during right radial coronary angiogram?
Consult this Twitter case on the management of a persistent kinking of diagnostic catheter (JR4) after failure of usual techniques.

How would you manage a persistent kinking of diagnostic catheter (JR4) after failure of usual techniques: smooth rotation in different directions, cross attempt with 0.035 or 0.014 wire or inflation of humeral tensiometer to fix the distal part of catheter and help to de-torque it?
Case Management
We used a snaring technique by femoral access to fix the distal tip of the catheter and so easily reshape the catheter by smooth rotation (videos 1 and 2).
Replacing the wire (0.035 or/and 0.014) is advised to optimize its reshaping and facilitate the catheter removal through the sheath (videos 3 and 4).
