Abstract:
Objective To analyze the safety and efficacy of coronary rotational atherectomy in elderly patients with coronary heart disease.Methods A total of 107 consecutive patients with coronary artery disease receiving rotational atherectomy from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into an ≥75 years group(n=44)and a ＜75 years group (n=63).We compared the characteristics of rotational atherectomy,peri-procedural complications,instant procedure success rates and 1-year cardiovascular events,including angina,re-infarction,hospitalization due to heart failure,repeat revascularization and cardiac death.Results There was no significant difference in the target coronary vessel,reference vessel diameter,maximal diameter of the burr and ratio of maximal diameter of the burr to reference vessel diameter between the two groups(all P＞0.05).Compared with ＜75 years patients,more ≥75 years patients used 2 burrs(10 cases or 22.7％ vs.4 cases or 6.3％,P =0.013),while there was no significant difference in terms of burr size,rotational time,maximal rotational speed,pre-and post-dilation pressure between the two groups (all P＞0.05).The incidence of peri-procedural complications had no significant difference between the ≥75 years group and the ＜75 years group(8 cases or 18.2％ vs.13 cases or 20.6％,P =0.753).One case of burr entrapment occurred in each group with successful retrieval.The procedure success rate was 96.8％(61 cases)in the ＜75 years group and 100％ in the ≥75 years group(P=0.640).No acute or sub-acute stent thrombosis or urgent coronary artery bypass graft occurred in the two groups during hospitalization.No cardiac death occurred in either group.Conclusions Coronary rotational atherectomy is effective and safe in elderly patients with coronary disease with a high instant procedure success rate.
