Excimer laser coronary angioplasty (ELCA) modifies atherosclerotic plaques through its photochemical, photothermal and photodynamic characteristics, while making up for the limitations of intimal disassembly and restenosis of balloon angioplasty without causing significant damage.The American Food and Drug Administration approved of the first clinical application of ELCA in 1992.Since then, ELCA has been used as an adjunct therapy in the treatment of various subsets of coronary artery lesions.ELCA considered to be a relatively safe and effective technique for coronary lesions when routine angioplasty is technically insuffident.[1-2] With the development of research on ELCA treating stent under-expansion in recent years, more and more evidences has shown that ELCA is effective in this situation.[3] Meanwhile, there is a high risk of restenosis and thrombosis due to stent under-expansion, which may be associated with serious clinical complications.Therefore, the management of stent under-expansion remains a clinically significant problem.
