Drug-coated balloon in interventional therapy for distal graft anastomosis lesions following coronary artery bypass grafting
Abstract：Objective To study the efficacy and safety of drug-coated balloon (DCB) in interventional therapy for distal graft anastomosis lesions following coronary artery bypass grafting (CABG).Methods Twenty-eight patients with distal graft anastomosis lesions following CABG were divided into observational group (n=16) and control group (n=12).The patients in observational group received DCB therapy and traditional ballon pretreatment of target lesions in case of need while those in control group received traditional ballon dilation therapy.The patients were followed up for 6 months,during which the operation efficacy,long-term outcome and incidence of cardiovascular events were recorded.Results No coronary perforation,pericardial tamponade and acute thrombus occurred in two groups during the interventional therapy.No sigflificant difference was found in the operation success rate between the two groups (87.5％ vs 91.7％,P=1.000) and in the instant minimal lumen diameter (MLD) between the two groups before and after operation (P＞0.05).The MLD was significantly longer in observational group than in control group (1.9±0.3 mm vs 1.6±0.3 mm,P=0.021).No cardiaogenic death,nonfatal myocardial infarction and revascularization occurred in two groups during the follow-up period.Conclusion DCB is effective and safe for distal graft anastomosis lesions following CABG.
