Directional atherectomy represents one potential approach for the trea
tment of restenosis in stented coronary arteries. In this case report
we demonstrate an important pitfall of this angioplasty technique for
stent restenosis-inadvertent entanglement of the stent wire in the dev
ice. While cutting and removal of part of the wire was achieved in the
case presented, this potential adverse event limits the applicability
of directional atherectomy for restenosis in coronary stents.
