Coronary calcification
Conditions
Interventions
rotational atherectomy+cutting balloon (RA+CB):we pretreated severely calcified plaque with rotational atherectomy(RA), with pre-dilation of the lesion achieved with a cutting balloon(CB)
rotational atherectomy(RA):the calcified lesion was pretreated with rotational atherectomy(RA) and a conventional plain balloon was selected for subsequent pre-dilation

All
Inclusion criteria
Inclusion criteria: These patients met the following inclusion criteria of the study: with at least one severe coronary stenosis >=70%, as indicated by angiography; with at least one severely calcified lesion of the target vessels, defined as a calcium arc of >=180 degree; and agreed to receive an RA or CB-based intensive modification of the plaque before PCI.
Exclusion criteria
Exclusion criteria: Patients were excluded from the current study for any of the following: acute thrombosis with unstable hemodynamic status requiring emergent PCI; previous PCI and presence of in-stent restenosis; extremely tortuous or angulated lesions or lesions with dissection before balloon expansion; lesion within a vein graft; or other complications or comorbidities which were contraindicated for angiography or PCI (e.g., severe renal dysfunction).
