Multi-center Prospective Study to Evaluate Outcomes of the Moderate to Severely Calcified Coronary Lesions (MACE)

This prospective, non-randomized, multi-center study includes subjects who meet all of the inclusion and none of the exclusion criteria and sign the ICF. This study may treat up to approximately 500 subjects at up to 50 active sites in the U.S. Subjects may be followed up to three (3) years. Subjects will be stratified into one (1) of three (3) arms based on the degree of calcification in the coronary lesion as defined by this protocol. The duration of the study is expected to be approximately four (4) years.
