Abstract:
Objective To evaluate the safety and efficacy of drug-coated balloon in small branch ostial lesions of coronary arteries (Medina type 0,0,1 lesion).Methods A total of 48 patients were enrolled in the study and they were randomly divided into the Drug-Coated Balloon (DCB) angioplasty group (22 cases) and the Cutting Balloon (CB) angioplasty group (26 cases).They underwent percutaneous coronary intervention (PCI) with either DCB or with CB in small branch ostial lesions of coronary arteries respectively,The immediate outcomes and long-term efficacy were investigated.Results There were no statistical differences between the two groups in baseline clinical date before PCI.There were no coronary perforation,pericardial tamponade,acute thrombotic events in the two groups.There was no significant difference in minimal lumen diameter (MLD) immediately after PCI between the two groups.During followup angiography,the MLD in the DCB group was significantly larger than in the CB group [(1.8 ± 0.2) mm vs.(1.5 ± 0.3) mm,P =0.006].There were no death,nonfatal myocardial infarction or revascularization recorded in the groups during 6 months of follow-up.Conclusion The immediate outcomes between DCB and CB were similar in small branch ostial lesions for coronary arteries angioplasty.The long-term efficacy of DCB angioplasty is better than CB angioplasty.
