Combined rotational atherectomy and cutting balloon angioplasty prior to drug-eluting stent implantation in severely calcified coronary lesions: The PREPARE-CALC-COMBO study.

Rota-Cut combination resulted in higher ALG and larger MSA compared with historical control of RA or MB alone, but was not associated with higher SE. Despite extensive lesion preparation, this strategy is safe, feasible, and associated with favorable clinical outcome at 9 months.
