ABSTRACT
Objective To analyze the complications of coronary rotational atherectomy and to evaluate the safety of the procedure. Methods We evaluated the procedural and angiographic outcomes of 248 consecutive procedures to rotational atherectomy between January 2000 and October 2016. Results 27 cases(10.9％)were found to have rotational atherectomy related complications. Among these 27 cases,coronary spasm occurred in 2 cases(0.8％),no reflow in 8 cases(3.2％), coronary dissection in 5 cases(2.0％),burr entrapment in 6 cases(2.4％),wire breakage in 3 cases(1.2％), and coronary perforation in 3 cases(1.2％). There were no death,acute myocardial infarction and emergent coronary bypass graft.14 case(5.6％)had PCI-related myocardial infarction during hospital stay.In-hospital major adverse cardiaccerebral event(MACCE)rate was 5.6％. Conclusions Coronary rotational atherectomy can be performed with high success rates and procedure-related complications are rare.
