Active Comparator
Rotablator
Conventional
Rotablator plus conventional angioplasty and/or stenting was performed in 120 patients in the R group. Rotablator using 140, -160, 000 rpm, small rota burr (burr-to-artery ratio, 0.6:1), avoid drop of >5000 rpm for 5s. Conventional intervention will be performed in the rotablator group. All subjects were given 100 mg/day aspirin and clopidogrel (300 mg loading dose and 75 mg/day maintenance dosage) at least 24 h before the procedure. A cutting balloon, buddy wire balloon, buddy wire, or DES (including sirolimus-eluting stent, paclitaxel-eluting stent, everolimus-eluting stent,zotarolimus-eluting stent) was implemented at the discretion of the operator in both groups.
Conventional angioplasty and/or stenting was performed in 120 patients in the C group. Conventional intervention without rotablator was performed in the C group. All subjects were given 100 mg/day aspirin and clopidogrel (300 mg loading dose and 75 mg/day maintenance dosage) at least 24 h before the procedure. A cutting balloon, buddy wire balloon, buddy wire, or DES (including sirolimus-eluting stent, paclitaxel-eluting stent, everolimus-eluting stent,zotarolimus-eluting stent) was implemented at the discretion of the operator in both groups.
