Abstract:
Objective To investigate the safety of intravascular lithotripsy(IVL)and coronary rotational atherectomy(RA)in the management of coronary artery calcification(CAC).Methods In this retrospective,matched-pair cohort study,210 patients with severe CAC treated at Zhongshan Hospital,Fudan University between December 2021 and April 2025 were enrolled.The cohort was equally divided into two interventional groups:IVL group(n=105)and RA group(n=105),based on the revascularization strategy employed.Procedure parameters,postoperative biochemical markers of myocardial injury,and incidence of in-hospital major adverse cardiovascular events(MACE)were compared between the two groups.Results Before propensity score matching(PSM),statistically significant differences were observed in terms of the proportions of the left anterior descending artery(77.1%vs.63.8%,P=0.034),the right coronary artery(14.3%vs.30.5%,P=0.005),and the percentage of target vessel stenosis[85%(80%,90%)vs.80%(80%,90%),P=0.014]between the IVL and RA groups.After PSM,these differences became insignificant(all P>0.05).There is no statistically significant differences in stent implantation rate,drug-coated balloon usage rate,stent diameter,or total stent length between the IVL and RA groups(all P>0.05).Compared to the RA group,although the IVL group had a higher utilization of tirofiban after the procedure,and a lower rate of intravenous nitrate during the procedure,these differences were not statistically significant(all P>0.05).cTnT levels increased significantly after the procedure in both the IVL and RA groups(all P<0.001).Before PSM,the preoperative cTnT levels were comparable between the IVL and RA groups(P=0.525),while a statistically significant difference emerged postoperatively(P=0.038).The incidence of in-hospital myocardial infarction showed no significant intergroup difference(8.6%vs.16.2%,P=0.094),and no events of death or target vessel revascularization occurred in either group.After PSM,despite no significant difference in preoperative cTnT levels between the IVL and RA groups(P=0.235),a significant difference was observed postoperatively(P=0.014).Furthermore,while no deaths or target vessel revascularization occurred in either group,the IVL group demonstrated a significantly lower incidence of in-hospital myocardial infarction compared to the RA group(9.9%vs.23.9%,P=0.025).Conclusions The use of intravascular lithotripsy for the pretreatment in patients with severe CAC is safe and promising.
