Objectives To assess long-term outcome after rotational atherectomy (RA) is followed by long drug-eluting stent (DES) implantation in diffuse calcified coronary lesions.
Methods Patients with diffuse calcified coronary lesions treated with RA following with long DES between January 2010 and December 2010 were investigated. Procedural success rate and clinical effect of postoperative visiting and main adverse cardiovascular events (including cardiac death, myocardial infarction and target lesion revascularisation) were recorded and focused on.
Results Twenty one patients with complex calcified coronary lesions were treated with Rota-DES. Mean age was 65.2 + 6.9 years, 16 patients (76.2%) had hypertension, 7 patients (33.3%) had diabetes mellitus and 1 patients (4.8%) had chronic renal failure. 35 stents were implantated. The overall procedure success rate was 95.2% (20/21) with the cost of 1 (4.8%) mexiletine, 1 (4.8%) gastrointestinal bleeding. Total stent length/patient was 48 mm (29-66 mm). There no patient has the incidence of in-hospital major adverse cardiac events (MACE). Long-term follow-up was available for all patients. At a median follow-up period of 26 months (range, 20–31), 1 (4.8%) patient patients had acute myocardial infarction.
Conclusions RA followed by long DES implantation in complex calcified coronary lesions appears to be feasible and effective, with a high rate of procedural success and low incidence of TLR and MACE at long term.
