Abstract:
Objective To evaluate the safety and efficacy of intravascular lithotripsy(IVL)in the treatment of coronary artery calcification lesions.Methods A total of 53 patients who underwent endovascular imaging guided treatment of coronary artery calcified lesions with either IVL or cutting balloon(CB)at the Affiliated Hospital of Jining Medical College from January 2023 to July 2023 were retrospectively analysed(IVL:n=18,CB:n=35)were retrospectively analysed to compare the technique,clinical success rate,major adverse cardiovascular events(MACE)and readmission for cardiovascular events in patients followed during hospitalisation and 1 month after the procedure.Results Clinical success rates were identical in the IVL and CB groups(100.0％vs.100.0％,P＞0.999),the minimum lumen area of lesions was similar in the VL and CB groups[(1.7±0.4)mm2 vs.(1.7±0.5 mm2),P=0.628].And there was a statistically significant difference in the overall mean lesion length between the IVL and CB groups[(28.4±9.6)mm vs.(20.9±8.6)mm,P=0.008].During the procedure,there were no complications such as aneurysm,thrombus,or emergency vessel closure.There was a statistically significant difference in the overall mean value of residual stenosis between the IVL and CB groups[(1.7±1.7)％vs.(6.9±2.0)％,P=0.049].There were no MACE in either group during hospitalisation or at the one-month follow-up(0 vs.0,P＞0.999),and 3 patients in the CB group were readmitted for angina pectoris(0 vs.8.6％,P=0.543),with no significant difference in readmission rates between the two groups.Conclusions The technique of intravascular lithotripsy is safe and effective in the treatment of coronary artery calcification lesions.
