- Abstract: OBJECTIVE: The aim of this study was to introduce the experience in treatment of acute ST segment elevation myocardial infarction(STEMI), saphenous vein graft(SVG), Chronic total occlusion(CTO),In-stent restenosis(ISR)and diffuse calcification lesions by excimer laser coronary atherectomy(ELCA). METHODS: Twenty-two patients were enrolled through our center from November 2016 to May 2017 and ELCA was performed on 22 lesions.The clinical and procedure endpoints were recorded. RESULTS: All the lesions were successfully crossed with laser catheterand and finally were performed by ELCA. Five cases(22.7%)with STEMI, ten cases(45.5%) with SVG lesions,five cases with ISR and other cases were CTO(4.5%) and Calcification(4.5%) lesions.Seventeen patients underwent balloon dilatation and successful implantation of drug-eluting stents(DES) and one patients was treated with drug-eluting balloon(DEB).the procedual and clinical success rates were 100%. At 6.6±2.7 months follow-up, there were no major adverse cardiac events(MACEs) and ELCA relatedcomplications recorded. Conclution This limited evdiences showed that treatment of complex coronary lesions by excimer laser coronary atherectomy may be a Safe and effective choice.It can be further popularized in complex coronary artery disease.
