In most instances, a JR4 catheter can be positioned into the subclavian artery ostium by counter-clockwise rotation and withdraw of the catheter after positioning it in the ascending aorta. Once the catheter is engaged in the subclavian artery ostium, any manipulation of the catheter has to be performed over the J tipped wire with extreme caution in order to avoid injury to the subclavian artery and embolism in the territory of vertebral artery.
