Abstract:
Objectives:To explore the therapeutic efficacy of balloon stent kissing technique(BSKT)and jailing wire technique(JWT)in patients with true bifurcation lesions of the left anterior descending branch-diagonal branch of the coronary artery,and to observe the impact of these two interventional procedures on the lumen area,angina symptoms,cardiac function,myocardial injury,and myocardial perfusion of patients.Methods:A retrospective analysis was conducted in 203 patients with true bifurcation lesions of the left anterior descending branch-diagonal branch who underwent BSKT and JWT procedures and completed a 6-month follow-up in the Department of Cardiovascular Medicine at Shijiazhuang People's Hospital from January 2022 to January 2024.Patients were randomly assigned to the BSKT group(n=107)or the JWT group(n=96).The safety,efficacy,and myocardial perfusion indicators of the two groups were compared.Results:The minimum lumen area measured by intravascular ultrasound immediately after procedure,the Canadian Cardiovascular Society angina classification at 6 months post-intervention,the total score of resting+stress myocardial perfusion at 6 months post-intervention,the total number of segments with resting+stress myocardial ischemia,and the abnormal myocardial perfusion area in both the BSKT group and JWT group were significantly improved compared to baseline values(all P<0.05).In the BSKT group,87 cases(81.3%)achieved immediate success in stent placement,whereas in the JWT group,64 cases(66.7%)achieved immediate success in stent placement.The BSKT group significantly outperformed the JWT group.In terms of the myocardial injury and cardiac function indicators assessed on postoperative day 1,the cardiac troponin I level([0.22±0.13]ng/ml vs.[0.45±0.27]ng/ml,P<0.001),creatine kinase MB([35.24±13.15]U/L vs.[42.39±21.66]U/L,P=0.004),and B-type natriuretic peptide([133.52±25.62]pg/ml vs.[167.22±22.04]pg/ml,P<0.001)were all significantly lower in the BSKT group than in the JWT group.In terms of the myocardial perfusion indicators at 6 months post-intervention,the number of ischemic segments under stress(3.23±1.54 vs.3.87±1.62,P=0.004),the total score of stress perfusion(4.18±2.21 vs.4.97±2.96,P=0.031),and the abnormal myocardial perfusion area([7.04±3.27]%vs.[8.24±3.69]%,P=0.014)were all significantly lower in the BSKT group than in the JWT group.Conclusions:Both BSKT and JWT procedures can significantly improve the lumen area of the left anterior descending branch,angina symptoms,and myocardial perfusion in patients with true bifurcation lesions of the left anterior descending branch-diagonal branch.The BSKT procedure provides more adequate protection for the bifurcation vessels compared to the JWT procedure.
