Abstract:
Objective To investigate the safety and short-term outcome of rotational atherectomy followed by drug-eluting stenting in heavily calcified coronary long lesions. Methods From Jan 1, 2011 to May 31, 2016, 109 cases with 114 heavily calcified coronary lesions which were treated with rotational atherectomy followed by drug-eluting stenting in Peking University People's Hospital were included. They were divided into diffuse lesion group ( lesion ≥25 mm, 68 cases, 72 lesions ) and focal lesion group (lesion ﹤25 mm,41 cases, 42 lesions). All patients were followed up in hospital. Procedure parameters, procedural complications ( dissection, perforation, slow flow/no flow and procedural related myocardial infarction),procedural success and major adverse cardiovascular events (cardiac death, non-fatal myocardial infarction and stent thrombosis) were analyzed. Results The procedural success rate was 98. 5%(67/68) in diffuse lesion group and 100% ( 41/41 ) in focal lesion group ( P=0. 453 ) . Complication rates did not differ between the two groups (41. 2% and 34. 1%, P=0. 673). Major adverse cardiovascular events rates were 41. 2% and 31. 7%, P =0. 484. Conclusions Treating coronary lesions ≥25 mm in length with rotational atherectomy followed by drug-eluting stenting does not impact the short-term outcome when treating carefully and correctly . Procedural success rate and in-hospital outcome is satisfactory.
