Spider ex embolic protection device was placed in a vg to distal rca in the standard fashion.After few minutes the operator realized that the tip of the spiderfx migrated down the small branch of distal rca.The spiderfx was then removed and the position of the separated tip was confirmed with ivus images.A coronary stent was placed in distal rca to cover the atherosclerotic lesion of the artery and to secure the tip of the spiderfx against the wall of the vessel so it does not migrate any further.The appropriate position of the stent and the spiderfx tip were confirmed with ivus images at the end of the procedure.
