Efficacy of transradial coronary rotational atherectomy in the treatment of heavily calcified lesions

Objective To compare the safety and efficacy between TRI and TFI in coronary rotational atherectomy for the treatment of heavily calcified lesions.Methods From January 2008 to September 2012,107 consecutive patients with heavily calcified lesions who underwent rotational atherectomy in our hospital were enrolled in this retrospective study.Patients were divided according to the vascular approach into two groups:transradial approach(TRI)and transfemoral approach(TFI).We compared the success rates of RA and stenting,rates of complication during perioperations,average time of lying in bed and hospitalization,MACE during hospitalization and after one year follow up.Results There were no differences in success rate of RA and stenting(100% vs 97.9%,P=0.265),RA and stenting complications(15.3% vs 18.2%,P=0.675;3.4% vs 4.2%,P=0.833),MACE during hospitalization and after one year follow up(7.9% vs 16.7%,P=0.156;3.4% vs 6.0%,P=0.516).But transradial rotational atherectomy was associated with a decrease in access site complications(3.4% vs 18.8%,P=0.009),average time of lying in bed and hospitalization(P0.001).Conclusions Rotational atherectomy through TRA is feasible,and its efficacy and safety is comparable to the TFA,and better accepted by patients.
