Novel treatment (new drug/intervention; established drug/procedure in new situation): Transfemoral contralateral technique to retrieve knotted coronary artery catheter using Amplatz Goose Neck snare catheter

摘要

Performing coronary angiography in very older patients can prove a challenge due to vessels calcification and torturousity. Manipulation of coronary catheters to engage the artery ostium may result in over twisting and can result in complications ranging from a minor ‘kink’ to a complex ‘knot’. The authors describe a novel method to retrieve the complex twisted coronary catheter using snare technique, after usual steps to remove the coronary catheter failed.
