RESUMO
<p><b>OBJECTIVE</b>To assess the clinical outcomes of rotational atherectomy followed by drug-eluting stenting via the transradial approach for the treatment of heavily calcified coronary lesions.</p><p><b>METHODS</b>From January 2009 to October 2012, 114 consecutive patients with heavily calcified coronary lesions underwent rotational atherectomy and drug-eluting stents via transradial approach in our hospital were enrolled in this retrospective study. Characteristics of heavily calcified coronary lesions, the success rates of rotational atherectomy and stenting, rates of complication during perioperative treatments, and adverse cardiovascular events during hospitalization and follow up were analyzed.</p><p><b>RESULTS</b>All 114 patients were successfully treated with rotational atherectomy and drug-eluting stent placement, and totally 120 target lesions of type B or C were treated including 8 left main lesions, 93 left anterior descending and 2 circumflex, 17 right coronary lesions. No-reflow was observed in 7 patients during the procedure, there was one case of entrapped rotablator burr which was successfully retrieved together with guiding catheter without serious complication. During the 6 months (median) follow-up, angina was reported in 11 patients and revascularization was performed in 8 patients due to stent restenosis and intensified medical therapy was applied in 3 patients. There was no acute myocardial infarction and death during follow-up.</p><p><b>CONCLUSION</b>Rotational atherectomy followed by drug-eluting stenting via transradial approach is feasible, effective and safe and the short-term outcome is satisfactory for patients with heavily calcified coronary lesions.</p>
