Long-term clinical outcome of rotational atherectomy followed by drug-eluting stent implantation in complex calcified coronary lesions.

Objectives: To assess long-term outcome after rotational atherectomy (RA) is followed by drug-eluting stent (DES) implantation in complex calcified coronary lesions.

Background: RA can favorably modify heavily calcified coronary lesions, but long-term outcome is poor when it is used as a stand-alone therapy or combined with bare-metal stents. DES have reduced rates of restenosis in a wide range of patient and lesion subsets, but little information is available on long-term clinical outcome when RA is followed by DES implantation (Rota-DES) in complex calcified lesions.
