Restenosis after coronary stent implantation remains one of the major limit
ations of this treatment modality. At present, redilatation is considered t
he therapeutic option of choice for focal lesions; however, long restenotic
lesions (>10 mm) do not respond favourably. Despite the emerging concept o
f intracoronary radiation, encouraging acute procedural results are also re
ported for different debulking techniques (excimer laser angioplasty, direc
tional coronary atherectomy, and rotational atherectomy, or rotablation).
