Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to evaluate the success of lesion preparation with either rotational atherectomy or cutting/scoring balloons as well as the long term effects of a hybrid sirolimus-eluting stent in an angiographically well-defined group of patients with complex calcified coronary lesions.
