Application of Excimer Laser Coronary Atherectomy for Treating the Patients With Coronary Chronic Total Occlusion / 中国循环杂志

ABSTRACT

Objective: To observe the safety and efifcacy of excimer laser coronary atherectomy (ELCA) for treating the patients with coronary chronic total occlusion (CTO). Methods: A total of 3 coronary CTO patients treated by ELCA in our hospital from 2015-01 to 2016-11 were analyzed. The patients received guide steel wire gone through occlusion segment under the guidance of offside coronary angiography; drug-eluting stent implantation was conducted after ELCA treatment. The operative success rate with complication was observed and the occurrence of MACE was followed-up. Results: The device performing and interventional therapy were succeed in all 3 patients. No coronary dissection, perforation, slow relfow and thrombosis were occurred during the operation; no angina, myocardial infarction, target vessel revascularization and death were observed by follow-up study. Conclusion: Application of ELCA combining drug-eluting stent implantation was safe and effective for treating the patients with coronary CTO.
