ABSTRACT
<p><b>OBJECTIVE</b>To investigate the safety and efficacy of rotational atherectomy followed by drug-eluting stent implantation for treating patients with heavily calcified coronary lesions.</p><p><b>METHODS</b>From March 1, 2010 to September 1, 2012, 65 cases with 78 heavily calcified coronary lesions which were treated with rotational atherectomy followed by drug-eluting stent implantation in Peking University People's Hospital were included, and 36 cases also underwent intravascular ultrasound to guide the rotational atherectomy procedure and drug-eluting stent implantation.All patients were followed up in hospital and post discharge. Procedure parameters, complications and major adverse cardiovascular events (cardiac death, non-fatal myocardial infarction, percutaneous coronary intervention related myocardial infarction, target vessel revascularization, recurrent angina, intra-stent restenosis and stent thrombosis) were analyzed.</p><p><b>RESULTS</b>Direct rotational atherectomy was performed in 64.6%(42/65) patients, rescued rotational atherectomy in 35.4%(23/65) patients, drug-eluting stents implantation was applied to all cases after rotational atherectomy. The immediate procedural success rate was 100% (78/78). The average burr/artery ratio was 0.50 ± 0.04, the average number of burr used per case was 1.15 ± 0.36. The average burr/artery ratio was 0.52 ± 0.03 and the average number of burr used per cases was 1.19 ± 0.40 in 36 cases guided with intravascular ultrasound. Five cases (7.7%) developed complications and were treated accordingly during procedure with satisfactory results. The incidence of major adverse cardiovascular events was 13.8% (9/65) during (17.6 ± 8.5) months follow-up.</p><p><b>CONCLUSION</b>Rotational atherectomy followed by drug-eluting stent implantation is a safe and efficient technique for treating heavily calcified coronary lesions.</p>
