Application Safety for Off-label Using of Rotational Atherectomy / 中国循环杂志

ABSTRACT

Objective: To explore the application safety for off-label using of rotational atherectomy. Methods: A total of 112 patients received rotational atherectomy in our hospital from 2010-01 to 2015-12 were enrolled in this study. There were 9 off-label indications for using of rotational atherectomy which included vein grafts, massive thrombotic burden, unprotected left main coronary artery disease, culprit lesions of acute myocardial infarction, severe coronary dissection, signiifcant impaired left ventricular function (LVEF0.05.②Off-label group had 1 patient with stuck of rotablator (1.5% vs 0%) and 1 cardiac death (1.5% vs 0%), both P>0.05; On-label group had 1 patient with acute in-stent thrombosis (2.2% vs 0%),P>0.05. Conclusion: Off-label using of rotational atherectomy did not increase the incidence of slow lfow/no lfow in relevant patients, other severe complications and in-hospital MACE occurrence were also rare.
