Combined rotational atherectomy and cutting balloon angioplasty for severe calcified coronary lesions
Abstract：Objective To assess the safety and efficiency of rotational atherectomy (RA ) and cut-ting balloon (CB) angioplasty for severe calcified coronary lesions according to intravascular ultra-sound (IVUS) .Methods Eighty CHD patients with at least one severe calcified coronary lesion detected by coronary angiography ,IVUS and RA were divided into RA group (n=34) and com-bined RA and CB angioplasty group (n=46) .The patients underwent IVUS before and after stent implantation .The outcome of stent implantation was assessed in the patients .Results The mean calcium arc and the mean calcium length ratio were lower in RA group than in combined RA and CB angioplasty group (215 .88 ± 21 .81° vs 226 .55 ± 21 .59° ,0 .72 ± 0 .06 vs 0 .78 ± 0 .05 ,P<0.05) .No significant difference was found in the minimum lumen area between the two groups before stent implantation (2 .52 ± 0 .07 mm2 vs 2 .46 ± 0 .09 mm2 ,P>0 .05) .The minimum stent area and acute lumen gain area were significantly larger in ombined RA and CB angioplasty group than in RA group after stent implantationin (6 .12 ± 0 .37 mm2 vs 5.42 ± 0 .24 mm2 ,3 .66 ± 0 .34 mm2 vs 2 .90 ± 0 .24 mm2 ,P=0 .016) .Conclusion Combined RA and CB angioplasty can achieve better stent implantation outcomes in patients with severe calcified coronary lesions .
