Abstract: Objective To assess the effect of coronary rotational atherectomy followed by drug-eluting stents implantation in patients age ≥65 years with complex calcified coronary lesions. Methods A total of 198 consecutive patients with coronary artery disease receiving rotational atherectomy from January 2016 to December 2017 were retrospectively analyzed.Patients were divided into an ≥65 years group(n=116) and a <65 years group (n=82). We compared the characteristics of rotational atherectomy, peri-procedural complications and 1-year major adverse cardiac events (MACE), comprised of cardiac death, miocardial infarction, target vessel revascularization. Results The incidence of peri-procedural complications had no significant difference between the≥65 years group and the<65 years group(18.9% vs 13.3%, P=0.202).And the rate of MACE was similar in the ≥65 years and <65 years groups (10.3% vs 7.3%, P=0.320). Conclusion Coronary rotational atherectomy followed by drug-eluting stents implantation is a safe and effective treatment strategy in patients age ≥65 years with complex calcified coronary lesions.

Key words: rotational atherectomy, drug-eluting stents, coronary artery disease
