Efficacy and Safety Analysis of Drug-coated Balloon in the Treatment of De Novo Coronary Chronic Total Occlusion Lesions
Objectives:To evaluate the efficacy and safety of drug-coated balloon in the treatment of de novo coronary chronic occlusive lesions.Methods:Consecutive patients with de novo coronary chronic occlusive lesions treated with drug-coated balloons only were included in this study.The general information,medical history,and surgical information of the patients were recorded,and major adverse cardiovascular events(MACE,including cardiac death,myocardial infarction,and target vessel revascularization)were recorded by telephone or outpatient follow-up.Results:A total of 160 patients were included.There were 26 ostial lesions(16.3%),42 bifurcated lesions(26.3%),117 diffuse lesions(73.1%),and 87 calcified lesions(54.4%).The reference vessel diameter was(2.3±0.4)mm.During hospitalization,there were no acute myocardial infarction,cardiac death,target lesion revascularization,or acute coronary thrombosis.Cardiac death occurred in 1 case and target vessel revascularization occurred in 6 cases during follow-up.The MACE rate is 4.4%.Conclusions:Drug balloon therapy for de novo coronary chronic occlusive lesions is safe and effective,and the prognosis is satisfactory.
