Abstract:

Objective To assess the efficacy and safety of Excimer laser coronary atherectomy（ELCA）in the treatment of resistant chronic total occlusion（CTO）lesions. Methods Fifty⁃one patients with severe resistant CTO lesions in Fuwai Yunnan Cardiovascular Hospital during May 2020 and August 2021 were included in the study，22 of them treated with ELCA and 29 with routine PCI. The plaque characters were analyzed and the final treatment effects were optimized by intravascular ultrasound（IVUS）after the successful procedures by which the balloons as well as the follow⁃up stents successfully went through the lesions and the residual stenosis was less than 20%. Results The total success rate of the two groups were 90.2%（46/51），that of the ELCA group reached 100% （22/22）and that of the non⁃ELCA group 82.7%（24/29）. Neither coronary perforation nor acute cardiac tamponade occurred during the operation in both the groups. Conclusion ELCA is a valuable tool for the treatment of resistant CTO lesions. It helps to achieve optimal outcomes for the patients with severe resistant CTO lesions.
